　　I. Adjust and improve the subsidy policy for popularization and application.

　　(1) Raise the threshold of the recommended vehicle catalogue and adjust it dynamically. The first is to increase the energy consumption requirements of the whole vehicle. According to the different kerb quality of pure electric passenger cars, the power consumption requirements of 100 kilometers under corresponding working conditions are increased; According to the vehicle type, the pure electric special vehicle increases the requirements of energy consumption per unit load (Ekg) and power consumption per ton and 100 kilometers; Further improve the energy consumption per unit load (Ekg) requirements of pure electric buses. The second is to improve the threshold requirements for the driving range of the whole vehicle. Improve the driving range requirements of pure electric buses and fuel cell vehicles, and timely adjust the driving range test method of new energy buses from 40km/h constant speed method to working condition method; Gradually increase the driving range threshold of pure electric passenger cars. The third is to introduce a new national standard for power batteries, improve the safety, cycle life, charge and discharge performance and other index requirements of power batteries, and set the energy density threshold of power batteries. Improve the technical requirements of fuel cell vehicles. The fourth is to improve safety requirements. For vehicles with safety accidents caused by product quality, depending on the nature and severity of the accident, the subsidy funds will be deducted and the vehicle or enterprise subsidy qualification will be suspended. The fifth is to establish a market sampling mechanism, strengthen the management of vehicle inspection links, and timely clean up the Catalogue of Recommended Vehicles for the Promotion and Application of New Energy Vehicles (hereinafter referred to as the Catalogue) for enterprises and products that fail to pass the sampling inspection. The sixth is to establish a dynamic management system for the Catalogue. Sales promotion of new energy automobile products can only apply for subsidies after they are included in the Catalogue. If there are still no models actually sold within one year, the qualification of Catalogue will be cancelled. Seventh, supervise and promote the application of new energy vehicles.When applying for subsidies for new energy vehicles purchased by non-individual users, the cumulative mileage must reach 30,000 kilometers (except for special vehicles for operation), and the subsidy standards and technical requirements shall be implemented according to the year when the vehicle obtains the driving license.

　　(2) Under the premise of maintaining the overall stability of the subsidy policy from 2016 to 2020, adjust the subsidy standards for new energy vehicles. For new energy buses, the power battery is the core of subsidy, and the production cost and technical progress level of the battery are taken as the accounting basis. The subsidy entry threshold such as energy consumption level, vehicle driving range, battery/vehicle weight ratio and battery performance level is set, and the vehicle subsidy standard is determined by comprehensively considering factors such as battery capacity, energy density level, charging rate and fuel saving rate. Further improve the subsidy standards for new energy trucks and special vehicles, and verify them according to the method of grading and regressing the battery power that provides driving power. At the same time, the upper limits of central and local subsidies are set respectively, in which the local financial subsidies (the sum of local financial subsidies at all levels) shall not exceed 50% of the central financial bicycle subsidies (the detailed plan is attached). In addition to fuel cell vehicles, the central and local subsidy standards and ceilings for all types of vehicles in 2019-2020 will be reduced by 20% on the basis of the current standards. At the same time, relevant ministries and commissions will constantly adjust and improve according to factors such as technological progress, industrial development, and scale of popularization and application of new energy vehicles.

　　(3) Improve the allocation of subsidy funds.

　　Scientists discover ferromagnetic quantum critical point evidence for the first time
　　The team of Yuan Huiqiu, a professor at Zhejiang University, discovered the ferromagnetic quantum critical point in pure heavy fermion compounds for the first time, and observed the strange metal behavior. The related results were published online in Nature on March 5. This is the first time that scientists have found conclusive experimental evidence of the existence of quantum critical point in a pure ferromagnetic material system, and observed strange metal behavior similar to that of high-temperature superconductors: when the temperature approaches absolute zero, the low-temperature resistance changes linearly with temperature, and the specific heat coefficient diverges logarithmically with temperature. This discovery breaks the traditional idea that ferromagnetic quantum critical point does not exist, and extends the strange metal behavior to ferromagnetic quantum critical materials, which opens up a new direction for the study of quantum phase transition.
　　Scientists discover accurate diagnosis and treatment of schizophrenia for the first time
　　Biological marker
　　Jiang Tianzai and Liu Bing team of Brain Network Group Research Center of Institute of Automation, China Academy of Sciences, together with researchers from many teams at home and abroad, broke through the bottleneck that the diagnosis and treatment of mental illness only depends on the empirical judgment of symptoms, and successfully established an accurate diagnosis and treatment model of schizophrenia by using multi-group information and artificial intelligence methods. For the first time, the research team found that the abnormal function of the striatum circuit in the brain is a biological marker for the accurate diagnosis and treatment of schizophrenia. Using this biological marker, not only can we quantitatively evaluate the pathological damage of striatum in individual patients, but also can accurately diagnose schizophrenia and predict the individualized curative effect. The imaging marker has been independently verified in patients with mental illness in multiple imaging centers and various populations. The research results were published in Nature-Medicine on March 23rd.

After 6 years’ research, the cancer and adjacent tissues of 103 patients with clinical lung adenocarcinoma were deeply analyzed by protein Group by using the cross-fusion research of protein omics, bioinformatics, tumor biology, pathology and clinical medicine. This work has scientific research significance for deeply understanding the pathological mechanism of lung adenocarcinoma, finding drug treatment targets and formulating more accurate treatment plans for lung adenocarcinoma.
　　Eight "magnifying glasses" relay to simulate the full-scale dark halo clear image of the universe.
　　An international research team led by the National Astronomical Observatory of the Chinese Academy of Sciences adopted a brand-new multiple amplification simulation technology, and obtained a clear image of the internal structure of the full-scale dark halo in the universe for the first time under the current standard cosmological model. The research results were published online in Nature on September 2nd. Dark halo is dark matter halo. It took the researchers five years, with the help of supercomputers, to obtain clear images of dark halos from earth-like mass to giant galaxy clusters, spanning 20 orders of magnitude. It is reported that in a typical area of the universe, this super-magnification simulation needs to be magnified by eight "magnifying glasses", and its magnification is equivalent to finding a flea on a picture of the surface of the moon. The super magnifying glass of computer simulation allows researchers to study the formation, evolution and internal structure of dark halos at different scales in detail. It is found that dark halos with different masses have very similar internal structures, that is, the center is dense and gradually sparse outward. These new findings will help scientists verify the hypothesis about the nature of dark matter-dark matter may not be "completely dark".
　　China’s first superconducting cyclotron was successfully developed.
　　On September 21st, the proton beam energy of superconducting cyclotron independently developed by China Institute of Atomic Energy reached 231MeV for the first time. This is the second time in the world to independently develop a compact superconducting cyclotron after the joint project of the United States and Germany. Researchers have successfully accelerated the continuous proton beam to this energy region, which indicates that China has fully mastered the core technology of miniaturization and high dose rate superconducting cyclotron and entered the international parallel ranks. The accelerator is small in size, low in power consumption and high in beam intensity, and can continuously accelerate 72 million proton beams per second. It is more suitable for fast intensity-modulated scanning therapy, breaking the monopoly of Europe and America in the field of miniaturized precision radiotherapy equipment, realizing the localization of superconducting cyclotron equipment in China, and is expected to greatly reduce the high treatment cost. The accelerator can also be directly used in the research and development of aerospace devices, core chips and integrated circuits, and promote the development of lightweight accelerators for aerospace particle beam applications, further opening up new fields of proton science research and application in China.
　　The third generation methanol to olefins technology passed the appraisal.
　　On November 9th, the third generation methanol to olefins (DMTO-III) technology passed the scientific and technological achievements appraisal organized by China Petroleum and Chemical Industry Federation. This technology is developed by Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and has completely independent intellectual property rights. Compared with the current industrialized technology, the economy of DMTO-III technology has been significantly improved. Under the condition that the reactor size is basically unchanged, the olefin output has increased from 600,000 tons to 1.15 million tons per year. DMTO series technology has opened up a new route to produce low-carbon olefins from non-petroleum resources, initiated and led a strategic emerging industry of coal-to-olefin production, which is of great significance for realizing clean and efficient utilization of coal resources, alleviating the tight supply of petroleum resources, promoting the coordinated development of coal chemical industry and petrochemical industry, and ensuring China’s energy security.

Original title: Just after the auspicious day of Wen Chang Xi Jun, I have prepared some gift boxes to help me study smartly and attentively, and recommend the Plus version.

In southern Fujian and Taiwan Province, Wen Chang has always been highly regarded, and everyone knows that he is the master in charge of the examination and writing of subjects, and he is a scholar who pays special attention to the title of subjects. The above pictures were taken by me earlier when I visited Wen Kui and Wenchang in Longshan Temple, Taipei, and they were also for the guests who married Wenchang.

Every year, the third day of the second month of the lunar calendar is the spring festival in Wenchang’s ceremony, and it is also one of the particularly good days to read books twice a year.One is on the third day of February, and the other is on the first day of August, which are auspicious days for you in Wenchang.）。

As in previous years, after the Spring Festival in Wenchang, San, in early February of the lunar calendar, some [Wenchang Kui] were also prepared for limited release to fans or their families who need to study more/learn their luck well in the coming year to protect your efforts.

People often ask, who can ask for education?

All kinds of students, company employees, and corporate employees can choose, and try their best to improve their intelligence and study smoothly. In addition to general academic evaluation, industry professional evaluation and workplace rating evaluation can all help (including small university, foreign language, and industry employees’ evaluation)

In the past, old customers always urged me to try my luck. Since it was launched, I have received quite a lot of positive feedback from to be no.1. I will briefly talk about three cases that benefited from Wenchang Daiwei and Wenchang Luojun:

In case A, an old man came to my guest for his own feelings, and he was preoccupied with his nephew’s future. My nephew lingered in the last third of the class before his graduation. At that time, he chose an auspicious time after 1: 00 a.m. to arrange Wenchang for her, but she gritted her teeth and did it anyway. Later, my nephew successfully got a copy.

World Football Day

These world cup cold knowledge

Do you know all about it?

Although the cold winter is coming, the football enthusiasm has not diminished. Tonight we will have a wonderful match between Croatia and Brazil, and today is the World Football Day recognized by the United Nations. Come and learn about the cold knowledge about the World Cup with Xiaobian and feel the charm of football!

Why is this year’s World Cup in winter?

In the past memory, the World Cup is always associated with summer, full of sweat, passion, beer and cheers. This time, however, FIFA World Cup Qatar 2022 was held in winter, which was mainly due to the Qatari climate.

Qatar is located in the desert area of the Middle East, with a tropical desert climate. In summer, the temperature is generally 25-46 degrees Celsius, and the highest temperature can soar above 50 degrees Celsius. This is really too hot for a player who wants to run for 90 minutes, and there is even the danger of heatstroke.

Of course, even in winter, the highest temperature in Qatar at the end of November can exceed 30℃, but the stadiums in Qatar are basically equipped with cooling systems to ensure that football players can play at a suitable temperature.

Why do players spit water?

This scene often occurs in football matches. Players take a sip of water and then spit it out immediately like gargling. Many friends will misunderstand when watching the ball. "Why do they spit everywhere?"

In fact, this is a way for players to drink water. The professional name is "carbohydrate gargle", which can effectively improve sports performance and relieve sports fatigue. It is a "scientific plug-in" for athletes on the field. They need to cheat their brains in this way without affecting their state, in order to quickly restore their physical functions and continue to play.

Why is there no British team in the World Cup?

There is no British team in the World Cup because there is no only football association in Britain.

In 1863, Britain, as the birthplace of modern football, established the world’s first football association: the English Football Association. In 1886, the football associations of England, Scotland, Wales and Northern Ireland jointly established the World Football Council and made unified rules. Later, FIFA generally joined football associations everywhere, so four football teams in Britain were invited to participate in the World Cup, namely, England, Scotland, Wales and Northern Ireland.

What is offside?

FIFA World Cup Qatar 2022 is in full swing, attracting countless fans to watch. In the first half of Argentina’s game against Saudi Arabia, it was blown offside six times, which made people confused. Many new fans will ask a question, what is offside?

Offside refers to the moment when the attacker passes the ball, the receiver stands closer to the goal than the penultimate defender, and at the same time closer to the opponent’s goal than the ball, and tries to prepare for the attack from this position. In other words, offside is an act that has a clear purpose, produces intentions quickly and puts them into practice. On the court, it is often seen that players are sentenced to offside because they start too fast and fall into the offside trap of their opponents.

The offside rule was formulated by the British Football Association in 1870. In the football match at that time, the audience often saw such a scene: when one side launched an attack, most of the attacking players had gathered in front of the other side, ready to start shooting when they received the ball, so the game between the two teams was mainly concentrated in front of the goal, and there was little wonderful cooperation. The offside rule is precisely to adjust this excessively unbalanced offensive and defensive relationship and make the game more exciting.

Swimming is a sport suitable for all ages. Proper swimming can not only make people happy physically and mentally, shape their bodies, but also enhance the function of cardiovascular system, physical fitness and human coordination. Next, let’s learn more about the benefits of swimming.

Athletes who leap into the swimming pool (Source: Xinhua News Agency)

1. Plastic body and beauty.Swimming is the best way to lose weight. When swimming in water, the body suffers great resistance. When swimming for more than a certain time, the fat in the body begins to burn. Even if you soak in the swimming pool, because the water temperature in the swimming pool is generally lower than the human body temperature, in order to maintain the body temperature, the human body will automatically consume heat. Therefore, exercising in water is more effective than exercising in the air, with twice the result with half the effort, and can also exercise the muscles around the internal organs.

2. Enhance cardiopulmonary function.This is because the blood return speed of the heart will be greatly improved by the friction of the water flow on the human body. This kind of systemic exercise increases the blood transfusion of the heart and brain, which is also beneficial to the prevention and treatment of cardiovascular diseases.

3. Enhance cold resistance.Human capillaries will contract when they meet cold water, and will expand due to lack of oxygen during exercise, which will enhance the ability of the nervous system to control the contraction and expansion of capillaries and enhance the cold resistance of the human body to some extent.

In addition, the World Wide Web pointed out that swimming can also improve people’s coordination, because swimming is a synchronized movement of limbs, and long-term swimming will make limbs more flexible. Swimming also has a certain skin care effect. In the process of swimming, water washes the skin, which can promote blood circulation and make the skin more moist.

Although swimming has many benefits, there are also precautions!

1. Avoid swimming on an empty stomach.In the process of swimming on an empty stomach, accidents may be caused by lack of physical strength, while over-satiated swimming will affect digestion and may cause stomach cramps and even vomiting.

2. Avoid swimming after strenuous exercise.Qilu Evening News pointed out that swimming directly after strenuous exercise will increase the burden on the heart, and rushing directly into the water after strenuous exercise will cause a sudden drop in body temperature. At this time, the human body’s resistance is weak and it is easy to cause a cold. So don’t jump into the water immediately after strenuous exercise.

3. Avoid swimming alone.It is best to choose a place with more people when swimming, so that you can get rescue in case of accidents. Beginners had better have people who can swim with them.

In addition, there are swimming places specially provided for babies in the market now, and swimming has become a sport for babies. What are the benefits of baby swimming?

The first is to promote physical development. People’s Daily pointed out that regular swimming can promote the development of the baby’s limbs, because the baby’s limbs are completely free to move during swimming and can complete coordinated and exquisite movements early. Swimming can also expand the baby’s vision, improve the reception of signals such as sound and color, and promote the development of the baby’s nervous system.

In addition, Life Times pointed out that infant swimming also helps to enhance metabolism and make the myocardium developed. It is helpful to the development of the baby’s brain and promotes the development of intelligence; Help to improve the function of respiratory system and increase vital capacity; It also helps to improve the baby’s ability to resist germs.

Before the baby swims, parents should make adequate preparations. First, try the water temperature. When the baby adapts to the water temperature, put it into the water completely and take it with the swimming ring. Immediately after landing, wrap the baby’s body with a bath towel to prevent catching a cold. (Cao Xu)
