Polaris solid waste network news: Coal gangue is a black-gray rock with a low carbon content and harder than coal, which is produced in the process of well construction, excavation, coal mining and coal washing. Coal gangue is solid waste produced in the process of coal production and processing, and its annual emission is equivalent to about 10% of the coal output in that year.
1. The production of coal gangue
In the coal mining industry, for every 100 million tons of coal produced in China, about 14 million tons of gangue are discharged. In the coal washing industry, for every 100 million tons of coking coal washed, 20 million tons of gangue are discharged, and for every 100 million tons of power coal washed, the amount of gangue discharged is 15 million tons. In recent three years, the output of new coal gangue is about 650 million tons.
As the largest coal-producing country in the world, China has a large number of coal gangue, which can be utilized as resources and improve the ecological environment of mining areas to ensure the green and sustainable development of modern coal mining enterprises.[1].
2. Relevant laws and regulations of coal gangue
In 1998, the State Economic and Trade Commission and other eight departments jointly issued the Management Measures for Comprehensive Utilization of Coal Gangue, which was revised in 2014. In order to guide and standardize the comprehensive utilization of coal gangue, reduce its impact on land resources occupation and environment, promote the development of circular economy and promote the construction of ecological civilization, detailed guidance was given to its comprehensive management and encouragement measures. Technical Policy Essentials of Comprehensive Utilization of Coal Gangue in 1999 took power generation, building materials production, backfilling and harmless treatment of coal gangue as the main direction of comprehensive utilization technology, and developed high-tech and high-value-added coal gangue comprehensive utilization technology and products. In 2012, the Technical Guidelines for the Utilization of Coal Gangue made detailed requirements for the use of coal gangue in different fields. In 2021, Guiding Opinions on Comprehensive Utilization of Bulk Solid Wastes in the Tenth Five-Year Plan pointed out the direction for the comprehensive utilization of bulk solid wastes such as coal gangue.
3. The characteristics of coal gangue
3.1 Physical characteristics
When coal gangue is piled up for a long time, it will spontaneously ignite when the internal temperature reaches a certain value, so coal gangue is often divided into undisturbed coal gangue and spontaneous combustion coal gangue. Among them, the appearance of undisturbed coal gangue is mostly black or gray-black, and the surface is mostly adhered with slime and fine coal gangue. Spontaneous combustion coal gangue has low carbon content, relatively high porosity, and the bulk density is between 0.9 and 1.3 g/cm3. The surface layer is mostly pottery red or pottery yellow, and there will be black centers due to insufficient internal carbon combustion.[2].
Fig. 1 undisturbed coal gangue (a) and spontaneous combustion coal gangue (b)[2]
The water absorption characteristics of coal gangue have great influence on its comprehensive utilization. Its porosity determines the water absorption characteristics of coal gangue, with water absorption of about 2.0-6.0% and plasticity index of about 3.0-15. The water absorption of spontaneous combustion coal gangue is about 3.0-11.6%, and the plasticity index is about 1.03-0.8.
3.2 chemical characteristics
The main chemical compositions of coal gangue are Al2O3, SiO2 and C, followed by CaO, Fe2O3 and MgO. The mineral components are mainly kaolin, hydromica, bauxite and carbon.[3]. The composition of coal gangue is influenced by different regions, and the composition of coal gangue varies greatly in different regions of China, so I won’t repeat it here.
3.3 Hazards of Coal Gangue
Coal gangue is a solid waste produced with coal mining. Except for partial filling and comprehensive utilization, most coal gangue is piled up for a long time to form a gangue hill, which occupies land resources. The harm of coal gangue to the natural environment is mainly reflected in the following aspects: 1. Coal gangue will form fine dust in the process of stacking and transportation, which will be suspended in the atmosphere under the action of wind, causing harm to human health. On the other hand, due to its own characteristics, coal gangue is prone to spontaneous combustion, releasing a variety of harmful gases and producing a large number of explosive smoke, so it will have different degrees of impact on the surrounding atmospheric environment and the growth of animals and plants. 2. In the process of coal gangue storage, the harmful elements in it will dissolve and enter the water body or soil environment under the action of rainfall, which will cause certain damage to the nutrients in the soil, and even lead to acidification of the land around the coal gangue hill, which will affect human health and vegetation growth.
4. Application of coal gangue
China began to use coal gangue as early as the middle of last century, and its comprehensive utilization began gradually in the middle and late 1970s. The comprehensive utilization of coal gangue is influenced by factors such as the ratio of aluminum to silicon and the content of carbon and sulfur, and it is mainly used for producing alumina, fuel, chemical raw materials, ceramic raw materials, building materials and road engineering filling.
Fig. 2 keyword co-occurrence analysis of comprehensive utilization of coal gangue in HowNet.
4.1 Production of Al2O3
There are many useful substances such as SiO2 _ 2 and Al _ 2O _ 3 in coal gangue. If it is extracted and utilized as bauxite, it can not only reduce the negative impact of coal gangue on the ecological environment, but Al2O3 alleviate the shortage of bauxite resources in China. At present, the methods of extracting alumina from coal gangue are similar to fly ash. The essence is to leach Al2O3 from coal gangue, mainly by acid leaching.[3]Alkali leaching method[4]Wait a few kinds. At present, the alkali method has been widely used in the actual production process. Acid leaching method is to use acidic solution to transform soluble components into salts and leach them into the solution, remove impurities from metal salts by adding reagents, and finally transform aluminum salts to form Al2O3. The main reactions are shown in (1)~(4). In order to improve its leaching effect, pre-activation is needed to improve the reactivity of coal gangue. Most of the extractant used in this process is strong acid, which requires high materials for industrial operation equipment and pipelines, and at the same time, there are many impurities accompanying leaching, which is difficult to meet the requirements of metallurgical grade Al2O3, limiting its industrial application in Al2O3 recovery.
Al2O3 + H2SO4 → Al2(SO4)3 + H2O (1)
Al2(SO4)3 + NH3·H2O → Al(OH)3 + (NH4) 2SO4 (2)
Al(OH)3 → γ-Al2O3 + 3H2O (3)
γ-Al2O3 → α-Al2O3 (4)
The alkaline leaching method is mainly Bayer method. The basic principle is to extract the crushed coal gangue with NaOH solution to obtain leaching solution of sodium aluminate and solid red mud containing silicon. After filtering and adding NaOH for seed decomposition, Al(OH)3 product can be obtained, and Al2O3 product can be obtained after calcination. The main reaction is shown in (5):
Al2O3·H2O + NaOHNaAl(OH)4 (5)
4.2 Production of building materials
Using coal gangue to prepare building materials mainly includes brick making, cement raw materials, ceramic materials and so on. Brick making. Brick making from coal gangue usually uses the calorific value of coal gangue itself to provide the required energy for drying and baking. The calorific value of coal gangue in China is 3300~6300 kJ/kg.[5]When the calorific value is low, some coal can be added for production, so making bricks with coal gangue can significantly reduce energy consumption. At present, the technology of making bricks from gangue in China is relatively mature, and solid gangue bricks, porous load-bearing gangue bricks and hollow gangue bricks have been developed and produced. Produce cement. The main components of coal gangue are SiO2 _ 2 and Al _ 2O _ 3, which are similar to the chemical composition of clay and can replace part of clay to produce cement. The crushed coal gangue is mixed with lime according to a certain proportion, and the clinker with calcium silicate as the main component is obtained after calcination, and then it is ground with gypsum and other materials to obtain cement with high compressive strength. Concrete aggregate. When coal gangue is used in aggregate, it usually needs a certain heat treatment to remove carbon and organic matter in coal gangue, so as to reduce weak components in coal gangue aggregate, at the same time, make the minerals in it edge, generate active substances and improve the surface activity of its aggregate. Wang Aiguo et al.[2]This paper studies the present situation of using coal gangue to prepare concrete aggregate in China, discusses the technical means to improve the performance of coal gangue aggregate concrete for a long time, and analyzes the existing problems.
4.3 Backfill and subgrade materials
Backfill. Because coal gangue is produced in the process of well construction, excavation, coal mining and coal washing, if the pollutant content is low, it can be used to fill the valleys, coal mining subsidence areas and low-lying areas for construction projects.[6]. Subgrade materials. As a road base material, coal gangue can be used for surface decoration of public squares, paving roads or parking lots, which can reduce the cost of subgrade, foundation or dam foundation construction and reduce the occupied land area. Backfilling and subgrade materials can realize the mass consumption of coal gangue, but these utilization methods fail to fully reflect the resource value of coal gangue, and valuable metals or other elements in it are not effectively utilized.
4.4 Other applications
Coal gangue can also be used to prepare building materials such as molding sand, ceramsite and ceramics, and multifunctional materials such as thermal insulation materials, refractory materials and cementitious materials, which are not described in detail here.
5. Insufficient utilization of coal gangue
Although the comprehensive utilization of coal gangue has made great progress, there are still some problems as follows. 1. The overall utilization level is not high. 2. The basic research on comprehensive utilization technology of coal gangue needs to be strengthened. 3. The research on comprehensive utilization technology of coal gangue is not deep enough. According to the "Guiding Opinions on Comprehensive Utilization of Bulk Solid Waste in the Tenth Five-Year Plan", it is necessary to strengthen the comprehensive utilization capacity of coal gangue, expand its utilization scale and orderly reduce its stock in the follow-up work. And make breakthroughs in key bottleneck technologies and establish its comprehensive utilization innovation system. We will continue to promote the application of coal gangue in engineering construction, subsidence area treatment, mine filling and other fields, guide the use of coal gangue to produce new wall materials, decoration materials, etc., and further promote its application in agriculture and the extraction of valuable components under the premise of controllable risks, and strengthen the application and promotion of high-yield and high value-added products.

"Big guy" debuts at full power, Jiangling Lexing new energy "full scene" shines at the 2023 Guangzhou Auto Show

At present, our country’s new energy vehicle market continues to make breakthroughs and usher in a high-quality development moment. When it comes to new energy transformation, we mostly think of passenger cars. In fact, China’s commercial vehicles have already started "synchronized walking and sprinting" in the field of new energy, and now they have entered the fast lane of new energy.

As a backbone enterprise in our country’s automobile industry and a large-scale enterprise group with commercial vehicles as its core competitiveness, Jiangling Automobile has been deeply researching the field of new energy in recent years. In March this year, the new brand "Jiangling Avenue" of Jiangling pickup truck was officially released in Beijing, and the new "sky survey architecture" technology platform carried by its models is compatible with fuel, range extension, pure electricity, hydrogen energy and other power systems. In October this year, Jiangling Ford’s latest replacement product, T8, was launched, and the Jiangling Ford E Quanshun brand made a heavy appearance. As the first pure electric platform of Jiangling Ford Light Passenger, the launch of Jiangling Ford E Quanshun accelerated the electrification process of Jiangling Light Passenger.

Wu Xiaojun, vice president of Jiangling Automobile joint stock company and CEO of Jiangling Lexing New Energy, said at a forum not long ago that new energy light commercial vehicles based on urban logistics scenes can greatly reduce fuel consumption, green and efficient, which is an inevitable way to reduce the cost of logistics enterprises and improve operational efficiency.

The determination of Jiangling commercial vehicles to practice the green road is clearly visible. At the just-held 2023 Guangzhou International Automobile Exhibition, Jiangling New Energy Commercial Vehicles made an unprecedented appearance. On the booth, Jiangling Lexing New Energy led Jiangling Avenue EV, Jiangling Ford E Quanshun, Jiangling Lexing E Luda and other "E series" legions to the stage, fully demonstrating the new achievements of Jiangling Light Commercial Vehicles in the era of digital intelligence.

Is the new energy army that Jiangling Lexing participated in this exhibition reliable? Is the motivation enough? In what aspects has intelligence been achieved? Pragmatic Jiangling uses data to speak and product descriptions.

At the auto show, Jiangling Avenue EV shone brightly. This new masterpiece, which integrates hard-core aesthetics and contemporary model technology, is an important product on the road of Jiangling’s practice of green and intelligent new paradigm of light commercial vehicles. For it, Jiangling has high hopes and will "inject" a number of hard nuclear power into it.

The power domain control battery pack on the EV on Jiangling Avenue was developed by Jiangling in cooperation with Ningde Times and Times Xin’an. This high-density and highly integrated product adopts the latest generation of CTP technology of Ningde Times, and the energy density of a single cell can reach 188Wh/kg. In addition, the "seven-in-one" power domain control integration technology is also applied to deeply integrate the software and hardware of the control module of the vehicle, electric drive and power battery, reducing weight, improving power and ESP response speed. At the same time, the vehicle is equipped with Bosch IPB intelligent integrated braking system, and the energy recovery ratio of CLTC operating conditions is 27%, which greatly improves the cruising range. The system has fast braking response and can implement all braking functions, including ABS anti-lock braking, EBD braking force distribution, TCS traction control, VDC body stability control, EPB electronic parking brake, etc., to enhance driving safety.

In terms of battery quality and quality assurance, Jiangling Avenue selects a new generation of long-term quality assurance lithium iron phosphate batteries in Ningde era, and the battery system quality assurance is 8 years or 400,000 kilometers. With Jiangling TMS 1.5 thermal management system, the batteries are stable and reliable in different temperature environments, and the battery life is extended.

Jiangling Avenue EV has a maximum operating range of over 500km and a maximum speed of over 140km/h. It has a large cargo space and an innovative super front box. Whether it is urban traffic, suburban travel, camping and fishing, or task modification, it can bring users an efficient and easy car experience.

On the booth, the "all-scene smart light passenger" Jiangling Ford E shines brightly. This is a light passenger with an actual battery life of more than 300km. Although it is powered by electricity, Jiangling Ford still continues the power performance elements of American vehicles, and has also achieved advanced intelligence and comfort.

In terms of power, the Jiangling Ford E Quanshun is equipped with an integrated battery pack and adopts an LFP battery system, which can achieve a cycle life of 3,500 times. The BMS hardware functional safety level of the Jiangling Ford E Quanshun is C. The integrated battery pack with a central layout can ensure that the energy absorption area of the battery is longer and safer during the front, back and side collisions. The low-speed collision battery pack has no effect at all. If there is a high-speed collision, it will complete the high-voltage power down within 41ms after the collision. In addition, the car battery is also monitored by the cloud platform 24/7.

Jiangling Ford E Quanshun applies Bosch IPB + RBU + EPB integrated braking system, efficiently integrates brake master cylinder & ESP, braking response is faster and brake response is more sensitive. Enhanced third-generation wheel hub bearings can be maintenance-free for life.

In terms of intelligence, the Jiangling Ford E is equipped with basic voice control, and can be equipped with a variety of intelligent solutions such as reversing image + AVM, Bluetooth key, remote air conditioning & automatic air conditioning, electric side door, etc.

Jiangling Lexing E-Luda was really the "big guy" on the booth, and its large physique made it gather more attention from the scene. It had a cool and technological front face at full speed "changing electricity", canceling the traditional China net and replacing it with a crystal blue label. In the dark, it came domineering like a mighty mecha warrior.

It also uses a mid-mounted integrated battery pack, which is placed in the middle of the frame to leave more space for the car body. Together with Ningde Times, Jiangling Lexing E Luda’s battery pack has a battery cycle life of up to 3,500 times. To make users feel at ease, the quality assurance cycle of the battery pack is 8 years or 400,000 kilometers. It is worth mentioning that the battery pack has achieved a waterproof grade of IP68, and there is no risk of continuous immersion in one meter of water depth.

Jiangling Lexing E Luda uses a flat-wire motor, which has strong heat dissipation, higher output power, and can suppress electric drive noise, and can adapt to temperature conversion in the range of minus 40 ° to plus 55 °.

Although it is a big guy, it can still achieve low wind resistance and self-rolling resistance due to its ingenious design. The car is equipped with an integrated shroud, which can reduce the air impact at the front of the container. The 13 ° gold A-pillar inclination and the integrated front face design take into account the shape and drag reduction. The wind resistance coefficient of the whole vehicle can be as low as 0.38, and the low roll resistance tires further reduce the resistance of the vehicle forward.

Jin Wenhui, the party secretary and first executive vice president of the joint stock company of Jiangling Automobile, is optimistic about the future pickup market in China. He said: "The scale of China’s pickup truck market may reach one million, two million or even three million."

It is worth rejoicing and pride that in the critical period of the collective transformation of our country’s automobiles to new energy, and in the critical stage of the high-quality development of China’s automobiles, Jiangling pickup trucks have achieved a smooth transition to new energy. Pickup trucks, light trucks and light trucks have the characteristics of large loading capacity, large volume and high weight commercial vehicles, which means that they must solve more problems in the process of transformation to new energy, but Jiangling has done it, and this booth is the best presentation of its results. In the future, Jiangling will continue to upgrade the above models on the existing basis, and promote large trucks, pickups and light trucks to a new field that integrates electric, intelligent and efficient.

The Ministry of Education answered a reporter’s question on "Measures for the Administration of Off-campus Training Materials for Primary and Secondary School Students (Trial)"

  Cctv newsAccording to the website of the Ministry of Education, recently, the General Office of the Ministry of Education issued the Measures for the Administration of Off-campus Training Materials for Primary and Secondary School Students (Trial) (hereinafter referred to as the Measures). The person in charge of the supervision department of off-campus training and education of the Ministry of Education answered the reporter’s questions on the relevant contents of the Administrative Measures.

  1. Q: Please introduce the background of formulating the Administrative Measures.

  A: First, implement the central decision-making and deployment. The CPC Central Committee attaches great importance to the work of "double reduction". In July this year, the general offices of the General Office of the Central Committee of the CPC and the State Council issued the Opinions on Further Reducing the Students’ Homework Burden and Off-campus Training Burden in Compulsory Education, explicitly requiring the establishment of a training content filing and supervision system, and formulating measures for the management of training materials in off-campus training institutions.

  The second is to implement the fundamental task of Lide Shuren. To fully implement the party’s educational policy and the fundamental task of cultivating people by virtue, we should not only strengthen the main position of school education, but also pay attention to off-campus training and education to build a good education ecology. In the stage of basic education, whether in or out of school, it is the responsibility to protect the healthy growth of children and promote their all-round development. There is no blank area or gray area, and training materials must be strictly controlled as a carrier of education.

  Third, the practical needs of standardized management. With the deepening of the governance of off-campus training institutions, all kinds of training materials have become the focus and difficulty of management. For a long time, there have been some problems in training materials, such as lack of guidance, standardization and scientificity, unclear requirements for its compilation, review and selection, and lack of system in training materials management. In practical work, it is urgent to strengthen the requirements of relevant norms and improve the system construction.

  2. Q: Please introduce the development process of the Administrative Measures.

  A: In the process of developing the Administrative Measures, we mainly carried out the following work: First, systematically sort out the literature. Conduct in-depth research on relevant national policies, special research results, and local documents such as the setting standards of off-campus training institutions in various provinces (autonomous regions and municipalities) and the management measures for off-campus training institutions, and grasp the existing work foundation. The second is to carry out multi-party research. For students’ parents and training institutions, Beijing, Fujian, Jiangxi, Henan, Shaanxi, Xinjiang and other provinces were selected to listen to opinions extensively, clarify the main problems existing in training materials, and clarify the key points and boundaries of the Management Measures. The third is to solicit opinions extensively. Insist on researching, drafting and revising. After the manuscript was formed, a special study was conducted, and opinions were solicited from provincial education administrative departments in two rounds, and opinions and suggestions were analyzed and absorbed one by one to improve the manuscript.

  3. Q: What are the training materials referred to in the Administrative Measures?

  A: The training materials referred to in the Administrative Measures refer to the learning materials for primary and secondary school students independently compiled by off-campus training institutions that have been approved and registered, including online and offline, disciplinary and non-disciplinary training materials. In other words, as long as all the materials used in training for primary and secondary school students prepared by training institutions are within the coverage of the Administrative Measures, there are no dead ends and no omissions.

  4. Q: What are the general requirements for the management of training materials?

  A: The Management Measures focuses on outstanding orientation, full control and dynamic supervision, and focuses on establishing and improving the management mechanism of training materials, which should not only solve current practical problems, but also be based on long-term development needs.

  First, insist on educating people. Off-campus training must adhere to the socialist direction and the public welfare nature. Therefore, the management of training materials should comprehensively implement the Party’s educational policy, implement the fundamental task of cultivating people by virtue, reflect the correct political direction and value orientation, follow the law of students’ physical and mental development, and constantly improve the ideological, scientific and appropriate training materials.

  The second is to strengthen the whole process of control. There are many links involved in the management of training materials, and no mistake or problem can be made in any link. Therefore, it is necessary to strengthen the whole process management of training materials, such as compilation, review, selection and filing, clarify personnel qualification requirements, quality standards and management norms of training materials, improve the management mechanism, and highlight the control and inspection of the whole process.

  The third is to strengthen social supervision. Training materials management includes both static editing and dynamic training use, involving employees, students, parents and other social aspects. Only by fully relying on the participation and supervision of all parties can the quality of training materials be ensured. Therefore, it is necessary to pay attention to comprehensive policies, dynamic supervision, establish smooth channels for information feedback and supervision and reporting, and actively play the supervisory role of industry organizations, professional institutions, the media and the public to form a multi-party joint force.

  5. Q: What are the requirements of the Management Measures for the quality of training materials?

  A: The Administrative Measures put forward clear requirements for the ideological, scientific and appropriate training materials: First, under the guidance of Socialism with Chinese characteristics Thought of the Supreme Leader in the New Era, it embodies the socialist core values, inherits and carries forward the excellent Chinese traditional culture, revolutionary culture and advanced socialist culture, spreads the scientific spirit, guides students to establish a correct world outlook, outlook on life and values, and promotes the healthy development of students’ body and mind; Second, the content is scientific and accurate, the capacity and difficulty are appropriate, and the content related to the national curriculum should meet the requirements of the corresponding curriculum standards and must not exceed the standard; Third, it conforms to the law of students’ growth and meets the multi-level and diversified learning needs, which is conducive to stimulating learning interest and encouraging exploration and innovation.

  At the same time, the "Administrative Measures" clearly emphasizes that it is strictly forbidden to uglify the image of the party and the country, damage the honor and interests of the country, undermine national unity, and promote religious superstitions in training materials. These are the bottom lines that must be firmly held, and they are also the negative list of training materials.

  6. Q: What are the requirements of the Administrative Measures for the qualifications of relevant personnel?

  A: The Administrative Measures mainly put forward corresponding requirements for the personnel who compile and review training materials.

  Editors of R&D should meet the following requirements: First, editors must pass the ideological and political barrier, stand firm in politics, support the Communist Party of China (CPC)’s leadership and Socialism with Chinese characteristics system, and have correct world outlook, outlook on life and values; Second, editors must be loyal to the party’s educational cause, fully implement the party’s educational policy, be familiar with the laws of education and teaching in primary and secondary schools and the characteristics of students’ physical and mental development, and have been engaged in education and teaching-related work for 3 years or more; Third, the editors must have a high professional and technical level, and the researchers who compile subject training materials should accurately understand and grasp the curriculum plan and subject curriculum standards, and have corresponding teacher qualification certificates; R&D personnel who compile non-discipline training materials should have relevant industry qualification certificates or professional ability certificates; Fourth, editors must have qualified moral sentiments, abide by the law, have a good ideological and moral character and social image, and have no bad records such as loss of morality, dishonesty, violation of discipline and illegality.

  Auditors should not only meet the requirements of writing R&D personnel, but also have a high level of policy theory and rich relevant education or training experience. When establishing the team of external audit experts, the education administrative department should also take into account the participation of experts from related disciplines, curriculum experts, teaching and research experts and front-line teachers.

  7. Q: How to classify and manage different types of training materials?

  A: Considering the actual situation in various places, the online and offline, disciplinary and non-disciplinary training materials are classified and managed.

  Discipline training is the key point and focus of the "double reduction" standard, and its supervision is stricter and higher. The "Administrative Measures" clearly stated that the disciplinary training materials should be double-audited by combining the internal audit of off-campus training institutions with the external audit of education administrative departments. On the basis of the internal audit of off-campus training institutions, the local education administrative departments shall assist the corresponding competent departments to carry out spot checks and inspections.

  Considering the different forms of online and offline discipline training materials, especially some databases, videos, etc., there is a lot of information and frequent updates. In this regard, the "Administrative Measures" also refined the corresponding management requirements, that is, requiring local education administrative departments to conduct a comprehensive review of basic materials in relatively fixed forms of online and offline training, and conduct spot checks on training materials in the form of databases, videos, etc., and encourage all localities to explore the use of modern information technology to strengthen the audit.

  8. Q: What are the requirements for the selection of training materials?

  A: The Administrative Measures strengthen the standards for the selection and filing of training materials.

  It is clearly required that off-campus training institutions should standardize the selection procedures of training materials. The selected training materials must be approved training materials or official publications. The selection of overseas teaching materials by off-campus training institutions should refer to the relevant provisions of the state such as the Measures for the Administration of Teaching Materials in Primary and Secondary Schools.

  Clearly require off-campus training institutions to keep all training materials on file for future reference, and the storage period shall be no less than 3 years after the corresponding training materials are used. Training materials and information of R&D personnel shall be filed with the corresponding education administrative department. When the filing materials are changed, the description of the changed contents and the changed materials shall be submitted in time.

  9. Q: What will happen if the training materials are used illegally?

  A: The "Administrative Measures" clearly states that if the training materials are found to be in violation of the provisions of these Measures, the education administrative department shall urge the relevant training institutions to make rectification within a time limit, and may deal with them in accordance with relevant regulations. During the rectification period, off-campus training institutions shall not use relevant materials to carry out any form of teaching activities. If the circumstances are serious or the rectification has not been completed within the time limit, the education administrative department shall revoke the license for running a private school according to law.

Internal communication and external communication, Tongjiang Dahai Nanchang strives to build a comprehensive transportation hub.

ten to seven

At present, the whole city is carrying out the strategic plan of "one hub and four centers" put forward by the provincial party committee and government to realize "two great promotions" with the sense of responsibility of taking the lead in "setting an example and striving for the first place", the spirit of "self-confidence and striving for Qi Xin" and the action of "saying one thing, doing one thing and doing one thing", firmly strengthening the province and welcoming the party’s 20th victory with practical actions. Starting from today (October 1st), the column of "Strong Province Will We Be in Action" in Daily News will report Nanchang’s vivid practice in building "one hub and four centers", developing digital economy, improving people’s livelihood and well-being, and building ecological civilization. Today, we first pay attention to "Building a Comprehensive Transportation Hub with Internal Communication and External Communication, Tongjiang Dahai Nanchang".

Perfect and convenient transportation network is the foundation of regional development. Our city insists on transportation first, speeds up the construction of a comprehensive three-dimensional transportation system with "internal smoothness and external communication", and promotes Nanchang to become an important strategic fulcrum for building a new development pattern in the country.

The West Second Ring Road Project of Nanchang Ring Expressway (Houtian-Lehua Section) is an important highway traffic line in the Greater Nanchang metropolitan area, with a total length of 86.58 kilometers. The route starts from Houtian Hub of Shanghai-Kunming Expressway, connects with Shanghai-Kunming Expressway, and forms a cross hub with Changzhang Expressway, passing through Honggutan District, Xinjian District, Anyi County, Wanli Administration Bureau and Nanchang Economic Development Zone, and finally ends at Nanchang North Hub, connecting with the East Outer Ring Road. After the completion of this project, it is of great strategic significance to promote the development of Nanchang’s "eastward expansion, southward extension, westward expansion, northward integration and Zhongxing", improve the city’s internal and external transportation network, and enhance the city’s radiation-driven ability.

Meiling tunnel is the only tunnel project in the whole line, and it is also the control project of the whole project. On the first day of the National Day holiday, the whole construction site was busy.

Liu Rui, executive deputy manager of the Fourth Bid Project Department of the West Second Ring Road Project of Nanchang Ring Expressway: "There are more than 200 workers on the construction site, and they are going all out to promote our construction tasks."

Focusing on the construction goal of "ensuring three years and tackling two and a half years", the earth and stone works of the whole line of the "West Second Ring Road" project are expected to be completed in April 2023, and the subgrade is basically formed; The main line pile foundation construction will be completed by the end of October 2022; By the end of 2023, the whole bridge was connected, and the whole project was completed in October 2024. By the end of August, 230 points of the West Second Ring Road project had been fully constructed. The earthwork of the whole line is 26.26 million cubic meters, and it is planned to complete 80% by the end of December this year. 63 bridges have completed 1975 pile foundations, with a completion rate of 33%. 27 culverts have been completed and 115 culverts are being excavated, with a completion rate of 39%; The planned investment for the whole year is 2.219 billion yuan, and the completed investment is 1.859 billion yuan, with a completion rate of 84%.

Speed up internal communication and external communication, and plan and lay out the urban trunk road network with high standards in our city. The reporter saw at the construction site of Hongzhou Bridge that the construction team was advancing simultaneously on both sides of the strait, and the construction of pile caps, piers and underwater pile foundations was under way.

Qiu Yanjian, chief engineer of Hongzhou Bridge Project in municipal public group: "We will not stop work during the National Day, and our goal is to complete the pile foundation construction of the whole line by the end of this year."

As the ninth river-crossing bridge in our city, Hongzhou Bridge connects Pingxiang Avenue and Xiaolan Avenue, connects the East Outer Ring Road to the east, and connects the West Outer Ring Road and Changli Expressway to the west, and connects Hangzhou-Changzhou Expressway, Daguang Expressway and National Highway 320, which plays an important role in optimizing the urban traffic layout and building a "one river and two banks" rapid transportation system.

Qiu Yanjian, chief engineer of municipal public group Hongzhou Bridge Project: "After the completion of Hongzhou Bridge, it greatly shortened the time to cross the river, ensured the smoothness of our passenger and freight traffic, and reduced the pressure of cargo crossing the river in shengmi bridge and the South Outer Ring Bridge."

In order to adapt to the new development pattern and the development needs of the greater Nanchang metropolitan area, our city seized the opportunity of the compilation of urban land space planning, promptly started the revision of urban trunk road network planning, and optimized and put forward the backbone road network system of "ten verticals, ten horizontals and ten links" on the basis of "ten verticals", with a total mileage of 730 kilometers, an increase of nearly 200 kilometers compared with the previous round, which will help our city to build a "one hub and four centers" and will also promote Nanchang to become an influential country.

Wang Yinghua, deputy section chief of the Municipal Department of the Municipal Bureau of Natural Resources and Planning, said: "With the gradual implementation of the trunk road network of’ ten verticals, ten horizontals and ten links’, the traffic in Nanchang will reach the goal of’ 103060′ in the future, that is, it will take 10 minutes to get on the trunk road of the city, 30 minutes to get on the expressway of the city, 60 minutes to get to the expressway outside the city and reach the Greater Nanchang metropolitan area."

Land extends in all directions, and water transport leads to the river and the sea. In recent years, Nanchang has continuously improved the modern water transport infrastructure system, accelerated the layout, expansion and upgrading of comprehensive terminals, brought into play the advantages of inland water transport, optimized the logistics path of Nanchang Port, and accelerated the realization of two-way opening. This is also an important measure for Nanchang to build a "one hub and four centers", unswervingly strengthen the province, comprehensively promote the construction of inland open economic pilot zones, and actively integrate into the construction of a "double cycle" new development pattern.

This year, part of the first phase project of Nanchang Yaowan Comprehensive Wharf in Nanchang County was put into use.

Li Jun, deputy general manager of Nanchang Water Investment Group Port Co., Ltd.: "From the opening of the port to the beginning of August, the tonnage of wharf hoisting exceeded 1 million tons in early August. Yaowan Wharf is based in Nanchang County, serving Xiaolan National Technology Development Zone and xiang tang International Logistics Park in Nanchang County. "

Yaowan Comprehensive Wharf is the largest comprehensive wharf project under construction in Nanchang Port at present, with 18 berths designed and built in the first phase. Its construction will fill the gap that there is no modern comprehensive wharf in the upper reaches of Nanchang city.

Optimize the function of port area and improve the efficiency of water transportation. Yaowan Wharf also plans to build roads and railways for port dredging, to keep close contact with other transport hubs, to develop multimodal transport, to expand the supply of high-quality transport services, and to make great efforts to expand the port economy. At present, Shugang Highway has completed the project establishment, planning and approval, and it is planned to start construction next year and be completed in 2024.

At present, a number of major key projects, such as the third phase expansion project of Changbei International Airport, Fuxing Bridge, Hongteng Elevated Road, the north extension and east extension of Metro Line 1, the east extension of Line 2, Changjing Huanggao Railway and Nanchang East Station, are being accelerated, and the modern three-dimensional transportation of "air, rail, public transport and water" is gradually becoming a reality.

[Ambassador sees China] Serbian Ambassador to China Milan Bacevic: "Iron buddies" are the best in the history of friendship.

  Cctv news(Reporter Li Yinan) For Chinese, the friendly relations between Serbia and China are well known to all women and children. The traditional friendship between the two countries, which began to sprout and take root during the Yugoslav period, and the Serbian literary and artistic works familiar to Chinese have witnessed the long-term and in-depth friendly cooperation between the two countries in the political, humanities, economic and trade fields.

  中塞友好关系影响了一代中国人,也正在积极影响着下一代。正是这一次次的经历与患难见证了中国与塞尔维亚间钢铁般的坚固友谊,这种既可锦上添花,更能雪中送炭的情义在中国过去5年的发展中再次得到印证。

  2016年6月17日,中国国家主席最高领袖对塞尔维亚进行国事访问,两国建立全面战略伙伴关系。今年5月16日,国家主席最高领袖在北京人民大会堂会见来华出席“一带一路”国际合作高峰论坛的塞尔维亚总统武契奇时表示,中方愿同塞方一道,巩固全天候友谊,全面深化各领域合作,推动中塞全面战略伙伴关系加快发展,在更高水平上运行,更好造福两国人民。

  The ambassador said that the friendship between the two countries as "iron buddies" has been developing continuously, and every bilateral contact and cooperation project has made the relationship between the two countries closer. "In the past four years, the top leaders of China and Serbia have exchanged visits as many as eight times. The visit of the chairman of the top leader to Serbia in 2016 is the first visit of the top leader of China to Serbia after a lapse of 32 years. This is not only a confirmation of the friendship between the two countries, but also provides new impetus for China and Serbia to deepen cooperation in various fields."

  The construction of the "flagship" cooperation project is progressing smoothly.

  Ambassador Bacevic said: "All walks of life in Serbia fully support the Belt and Road Initiative proposed by the Supreme Leader, and President Vucic has clearly expressed Serbia’s support and concern for this initiative. The superior geographical location of Cyprus is also very beneficial to connecting China and Europe. "

  According to the ambassador, China and Serbia signed a total of eight relevant agreements at the "Belt and Road" international cooperation summit forum. “‘ Belt and Road ’ The initiative not only creates new opportunities for world connectivity, but also provides an excellent opportunity for the development of Serbia and the whole Central and Eastern Europe. China and Serbia have great potential for cooperation in the fields of energy, agriculture, tourism, culture and non-governmental exchanges, especially in infrastructure construction in transportation. " Ambassador Bacevic said, "The Belgrade-Budapest high-speed rail project jointly built by China and Serbia is a good example, and this is just one of many cooperation projects between the two countries."

  The well-known Sino-Serbian "One Belt, One Road" cooperation project, Hungarian Railway, is the first transnational railway jointly built by China enterprises in Europe. As the flagship project of cooperation between China and Central and Eastern Europe, the completion of the railway will become another milestone for China’s high-speed rail to go global. "This is a very important infrastructure construction project in China-Serbia cooperation, and it is progressing smoothly." Ambassador Bacevic said that the construction of the first section of the Hungarian-Serbian Railway in Serbia will begin in November this year, and the preparations for the remaining section will be completed soon. "The project has entered the most important stage and will be completed as scheduled."

  The ambassador believes that Hebei, China Iron and Steel Group’s acquisition project of Smederevo Steel Plant is very successful, and it is an investment model showing social responsibility. He emphasized that this project is not only the most important project to ensure the economic stability and growth of Serbia, but also a model that other China enterprises can follow in investing in Serbia in the future. The Ambassador sincerely expressed the hope that there will be more investment from China like Hegang in the future.

  We are not only partners, but also sincere friends.

  Ambassador Bacevic pointed out that the two countries can also make direct investment in accordance with the principles of market economy in the future. He said: "Serbia welcomes China enterprises to seize the huge investment opportunities in food industry, automobile, metal products, machinery manufacturing, electronics industry, information and communication technology and other industries and conduct business activities in Serbia."

  He stressed that investors from China are the most popular in Serbia. "I want to take this opportunity to call on China tourists and businessmen to visit Serbia. Here, you will not only find partners, but also find the most sincere friends."

  Ambassador Bacevic said that Serbia is the second European country to establish a visa-free system with China, and the visa-free policy has promoted mutual understanding and cooperation between the two countries. Following the visa-free policy came into effect in January 2017, the long-awaited direct flight between Belgrade and Beijing was officially launched in mid-September.

  China wisdom promotes the steady development of the country.

  As an ambassador to China who has worked and lived in China for many years, Mr. Bacevic said that in the years since the 18th National Congress, China has made important development achievements in various fields. The ambassador especially praised China’s diplomatic direction and foreign policy. "The pragmatic cooperation between China and Serbia has not only become closer but also doubled in recent years. Through political dialogue, economic and trade cooperation and various rich activities, the scale of cooperation in various fields has nearly tripled compared with a few years ago."

  他指出,这得益于“一带一路”倡议的合作共赢新模式。它不但为塞尔维亚以及整个中东欧地区带来了新的发展动力,更为全球发展带来了新的活力。

  巴切维奇大使说:“十八大以来,中国在经济、环保、反腐、消除贫困等方面取得了引人瞩目的成果,我相信很多国家都可以从中学到不少东西。”大使表示,他与全球所有关心中国的人一样,希望中国能够继续推进改革,促进经济发展并保持与其他国家合作的新模式。

  他认为,中国关于实现“两个一百年”的新计划、新政策一定会成为世界关注的焦点。巴切维奇大使借助央视网的平台,表达了他对中国最美好的祝愿,“祝中国成功实现目标,继续用中国智慧推进国家的稳步发展和长治久安。”

I thought that the "VVIP storm" of Tencent video triggered by the hit drama Joy of Life had gradually subsided, but last Friday, the column "News Brother" of Tencent News published the title "Chinese doesn’t deserve a spiritual life! Not worthy! "(hereinafter referred to as" unworthy ") has once again pushed Tencent to the forefront.

In the early morning of December 23rd, "News Brother" issued an apology statement on its WeChat WeChat official account, saying that the person in charge of WeChat official account would be replaced from now on, and the relevant editors of this article would be suspended.

The apology statement stressed that the article "Unworthy" was seriously inappropriate in terms of title, viewpoint and wording. "We recognized the mistake and deleted the article. This article does not represent Tencent’s attitude towards the video membership incident in Joy of Life. Previously, the Tencent video team has already reflected and explained this. All members of the team will reflect deeply and take this as a warning to live up to everyone’s expectations. "

The team of "News Brother" said that the person in charge of WeChat official account will be replaced from now on, and the relevant editors of this article will be suspended; At the same time, the editorial process in WeChat official account will be optimized and improved to ensure that such incidents will not happen again.

Previously, the advance VOD event in 50 yuan, Joy of Life aroused public concern and was dubbed "VVIP" service by netizens.

Tencent revised the rules under controversy.

After the release of the new regulations, it immediately became a hot topic on the Internet. Weibo @ People’s Daily also issued a comment saying: "Setting VVIP outside VIP, paying extra money to enjoy advanced on-demand video sites is creating anxiety and inducing user consumption." In addition, the People’s Daily also pointed out that if this kind of extra payment behavior is not indicated in the VIP user agreement of the video website, it is actually a violation of consumers’ rights and interests.

After becoming the target of public criticism, Wang Juan, editor-in-chief of Tencent Video, said that the controversy was "not considerate enough" in informing members and grasping consumer psychology. Subsequently, Tencent Video revised the advanced on-demand rules.

Just as the public opinion gradually subsided, last Friday, the column "News Brother" of Tencent News published the article "Unworthy". The article said, "Why can’t you charge for good content? Do people who create content deserve to die of poverty? " , "Joy of Life vvip this thing, too expensive 50 yuan is false, don’t want to spend a penny is true".

Finally, the article concludes: "This is the current situation of China’s content market. This is the reality that Chinese doesn’t deserve a spiritual life at all! After all, Chinese does not deserve it. "

It is worth noting that after the publication of this article, Li Nan, a former Meizu executive, made an opinion on this article in Zhihu on 22nd, saying that the huge loss of video platform just proved the success of the game between content and platform. "Because the platform loses money, it is not that it can’t receive money, but that it has to pay more copyright fees, and the money is really given to the content creators."

"Chinese’s willingness to pay for content is quite strong. The data and traffic we see follow the content, and the platform is actually not loyal. This is a healthy ecology." He pointed out, "Originally, users paid a lot, so it should not be a problem to support content creation (a small-budget movie can also sell more than 300,000 box office)."

In his view, the production cost and cost of actors in China today are so high that video platforms compete for copyright and raise prices.

Li Nan said that it was the coquettish operation of Tencent’s vvip that caused the negativity that should not have existed now. "I don’t come out to apologize, I don’t have the consciousness of holding public opinion, and I even educate users."

Why do you want to test nucleic acid when you go back to work? Can a cold affect the test results? Disease control experts tell you!

Today’s Lantern Festival, after the Lantern Festival, even if the year is over, "migrant workers" will return to work one after another, and teachers and students will also enter the countdown to returning to school.

Sichuan disease control experts remind everyone that it is necessary to measure nucleic acid in time in order to reduce the risk of post-holiday epidemic spread.

So, where are we going to do it? What are the precautions?

1. Why do you want to do nucleic acid testing when you advocate returning to school?

Recently, the global COVID-19 epidemic continues to spread, and the domestic COVID-19 epidemic shows a multi-point distribution trend, with many local confirmed cases and asymptomatic infected people. The prevention and control situation is still severe and complicated. Our province is a populous province and a tourist province, with a large population density and a large floating population. On the one hand, a large number of migrant workers and tourists returned to Sichuan from all over the country during the Spring Festival, and on the other hand, a large number of people returned to Sichuan from outside the province after the holiday. In addition, during the Spring Festival, various gathering activities such as dinners and parties were frequent, and the mobility and gathering of people increased greatly, which greatly increased the risk of epidemic spread.

How to check the potential risks? Nucleic acid detection is the fastest and most convenient means. Nucleic acid detection is the primary measure to normalize prevention and control and implement the "four early" measures. Through nucleic acid detection, we can realize "early detection", directly find the evidence of the existence of the virus, and find the source of infection in time, thus blocking the transmission route and controlling the spread of the epidemic.

For example, on February 12, one of the two newly confirmed cases in Yunnan was found among active nucleic acid testers; On the evening of February 13th, among the patients in the fever clinic and the "willing to do all the tests" in Suzhou, four patients with positive results in the initial screening and recheck of nucleic acid detection were also found.

Therefore, in order to reduce the risk of post-holiday epidemic spread, ensure that there is no cluster epidemic, ensure everyone’s safety, and let everyone return to work happily, go to work with peace of mind, and go to school with peace of mind, it is suggested that everyone must do nucleic acid testing in time.

In addition, nucleic acid detection will not cause any harm to the human body. Only when collecting throat swab, the cotton swab will feel a slight foreign body sensation when it goes deep into the throat.

2. Who wants to do nucleic acid testing?

(1) Returned personnel

1. High risk positions

Front-line staff of customs, border inspection and port, aviation service personnel, staff related to imported cold chain food, staff in high-risk positions such as centralized isolation places and medical institutions should provide negative proof of nucleic acid detection within 48 hours when returning to work, and then conduct a nucleic acid detection within 24 hours after returning to work; If you can’t provide negative proof of nucleic acid test within 48 hours, you need to carry out nucleic acid test twice every 3 days (24 hours apart) after returning to work.

2. Key positions

Staff of disease control institutions, frontline staff of market supervision system, employees of farmers’ (bazaars) markets and supermarkets (excluding employees of imported cold chain food), employees of service industries such as take-away, postal service and express delivery, all employees and service personnel of transportation stations and service areas such as airports, railway (including high-speed rail) passenger stations and highway long-distance passenger stations, domestic transportation industry personnel, and grassroots epidemic prevention and control investigators, Service personnel of tourist attractions, song and dance entertainment places, staff of party and government organs and other state-owned enterprises and institutions, etc., should provide negative proof of nucleic acid detection within 48 hours; If you can’t provide negative proof of nucleic acid test within 48 hours, you need to conduct a nucleic acid test within 24 hours after returning to work.

3. Other returning workers are advised to take the initiative to do a nucleic acid test as soon as possible when they return to work, so that their families can rest assured and feel at ease!

(2) Returned students

Teachers and students of colleges and universities in the province return to school with negative nucleic acid test certificate and Sichuan Tianfu health pass green code within 48 hours before registration; If you can’t provide negative proof of nucleic acid test within 48 hours, you need to conduct a nucleic acid test within 24 hours after returning to school.

Teachers, students and employees of primary and secondary schools and kindergartens in the province and their family members who live together have no history of living outside the province or close contact with people who have returned to Sichuan from outside the province within 14 days, and they can return to school with the green code of Sichuan Tianfu Health. After the school checks the travel code of themselves and their family members who live together, it is not necessary to provide negative proof of nucleic acid test.

Teachers, students and employees of primary and secondary schools and kindergartens in the province or their family members who live together have a history of living outside the province within 14 days and a history of close contact with people who have returned to Sichuan from outside the province. When returning to school, they should provide negative proof of nucleic acid testing within 48 hours; If you can’t provide negative proof of nucleic acid test within 48 hours, you need to conduct a nucleic acid test within 24 hours after returning to school.

Personnel in key positions such as logistics management and temporary employment assistance in schools and kindergartens at all levels need to return to school with negative proof of nucleic acid test within 48 hours before registration and Sichuan Tianfu Health Pass Green Code, and schools should strengthen their normalized nucleic acid sampling monitoring.

3. Where to do nucleic acid testing?

In order to make nucleic acid detection more convenient, during the period of Spring Festival travel rush, on the basis of the conventional medical institutions for nucleic acid detection, a total of 672 convenient nucleic acid sampling site were added in the province. Among them, there are 13 airports; 55 train (high-speed rail) stations; 132 bus stations; 115 high-speed intersections; 23 scenic spots; There are 334 other squares and communities (townships). Provide timely and nearby nucleic acid sampling and testing services for people who are willing to complete the inspection.

Individuals who need testing can consult and make an appointment through WeChat and telephone, and choose the corresponding institution nearby for testing, or they can make inquiries through "Sichuan Tianfu Health Link", a popular service, medical and epidemic prevention institutions.

4. Where can I get the test results?

You don’t need to go to a testing institution to get a paper report, but you can directly pass the test results of nucleic acid and antibody through "Sichuan Tianfu Health Link", a popular service.

5. What are the precautions for nucleic acid testing?

(1) The "Sichuan Tianfu Health Code" should be scanned during nucleic acid testing and sampling. If there is no code, you need to bring your ID card, and the person’s ID card will be integrated.

(2)Try to avoid eating 2 hours before sampling to avoid vomiting and other discomfort; Try not to drink water or drink, smoke, drink or chew gum for 30 minutes before sampling.

(three)When sampling, try to reduce swallowing movements, swallow less saliva and not clear your throat.

(four)After sampling, leave the site as soon as possible, and wipe your hands with hand-free disinfectant or hand-free alcohol, sterile cotton pads, etc.

(five)Obey the arrangement and guidance of the sampling site staff, strictly implement the requirements of epidemic prevention and control, adhere to scientific norms to wear masks, keep a safe distance of more than one meter, and improve self-protection awareness and ability.

Tips

1. I caught a cold during nucleic acid testing. Will it affect the test results?

No. If the symptoms of upper respiratory tract infection are not caused by Covid-19, the kit can’t accumulate enough immunofluorescence, and the specific nucleic acid sequence of Covid-19 can’t be detected in patients’ samples, so there is no need to worry about being "misjudged".

2. Suffering from pharyngolaryngitis and phlegm in the throat will affect the test results?

No. The main causes of pharyngolaryngitis are recurrent acute pharyngitis, irritation of inflammatory secretions in nasal cavity, paranasal sinuses and nasopharynx, direct spread of chronic tonsillitis, stimulation of excessive alcohol and tobacco, dust, harmful gas and air pollution, and overeating spicy food. Covid-19 nucleic acid test is a specific test, which is a manifestation of Covid-19’s infection, so it will not affect the test results.

3. Did drinking wine the day before affect the test results? Do you need an empty stomach before testing?

Will not affect the test results, and do not need an empty stomach. However, it is suggested to avoid eating as much as possible before nucleic acid detection to avoid vomiting. Try not to smoke, drink or chew gum before sampling to avoid false negative results.
