Compact family car three cars compete for hegemony, and the new Qin EV rides the dust!

Under the epidemic situation, health and safety have become the top priority of all needs, and based on the consideration of travel safety, people are increasingly inclined to travel by car. Not long ago, the lottery results of the new passenger car were announced. For the lucky ones who just got the index, how to choose a reliable car is very important.

As the main model in the market, the epidemic prevention and sterilization capabilities of brand new, BEIJING EU5 and brand new have reached the professional level, and brand new has become the leader in the compact pure electric family car market with its strong and numerous fan base. So if you want to choose a safer, stronger and more practical one among these three cars, who will be the better option?

Who is the strongest in protecting health and professional sterilization and antivirus?

To be healthier and safer, we must first have stronger sterilization and antivirus ability. The newly equipped three-layer high-efficiency composite filter screen can filter dust, harmful gases, PM2.5 particles with a diameter of > 0.3 μ m up to more than 90%. Its filter screen consists of non-woven fabrics and chemical fibers, and is made by melt-blowing process, which can better filter droplets and particles with diameters greater than 0.3 μ m that germs often attach to, thus effectively blocking germs from entering the car. In addition,BYD’s self-developed high-efficiency filter has obtained the first batch of "CN95" certification of the highest level of automotive air-conditioning filter filtration, and will be fully equipped with this system for more old models in the future to further improve health and safety performance.

At present, the filtration system carried by EU5 has been upgraded on the basis of filtering pollen and PM2.5; On the other hand, a UVC deep ultraviolet optical anti-virus system was installed for Ei5, but there are still concerns that "ultraviolet anti-virus will have adverse effects on human body" in the market at present. It is not difficult to see that the new health care is more professional and leading.

Guarding safety, the brand-new Qin EV power battery has a 16-year accident.

If health is a higher demand of consumers, then the demand for vehicle reliability is the basic demand of all consumers. In the world, this basic requirement includes the reliability of endurance, the reliability of battery, and the reliability of the overall performance of the vehicle, etc. If the technical performance of any aspect is not strong enough, there is no way to talk about safety, and no one can trust a brand of new energy vehicles with frequent vehicle spontaneous combustion. 

From the comparison of the above figure, the brand-new battery has higher energy density and can store more electricity per unit volume, so its comprehensive endurance is stronger, and at the same time it can have more room for lightweight.

While continuously improving the energy density, a 7-dimensional and 4-layer safety matrix has been built for brand-new power batteries, which "comprehensively tests the safety of single batteries, modules, battery packs and systems from the aspects of reliable connection, high-voltage protection, collision, overcharge, internal and external short circuit and thermal runaway; The high-voltage system has undergone five tests: leakage detection, power-off protection, misoperation protection, active discharge and passive discharge, and the whole vehicle has undergone extreme cold and heat tests, which fully guarantees the safety of the battery. "

If these terms seem hard to you, then the accident in 16 years will definitely make you easily realize the reliability of the battery.The accident in 16 years first benefited from BYD’s technical advantages in battery safety design.In order to avoid the thermal runaway of the battery caused by the short circuit in the battery caused by the contraction of the diaphragm at high temperature, a ceramic diaphragm with more high temperature resistance was developed. In order to cope with high and low temperature environment, prevent overcharging, improve fast charging safety and flame retardant, etc., many special additives are added to the electrolyte solution of the battery cell on the basis of the original solute and solvent to ensure the stability under various complex conditions; In addition, in order to protect the safety of the battery cell, a mechanical device, including a CID device and an explosion-proof valve, is arranged on the shell of the single battery cell to prevent overcharging. These technical advantages are integrated into the battery intelligent temperature control management system, which is not only smarter, but also greatly improves the consistency and stability of products.The new Qin EV is equipped with BYD’s third-generation battery intelligent temperature control management system, which can make the battery in the most efficient working range at various ambient temperatures, greatly improving the battery life cycle performance, life span and safety.

Secondly, the accident in 16 years can be achieved thanks to all the self-research and self-production of the three power systems. Compared with peers, it has higher integration, more advanced consistency and integrity, and a stronger degree of systematization.BYD’s brand-new Qin EV efficiently integrates the motor, electronic control and transmission, which reduces the volume by 30% and the weight by 25%, while increasing the power density by 20%.

EU5 and Ei5 are made in Contemporary Amperex Technology Co., Limited, and although they have passed the battery safety test, the integration is not enough, and the consistency and integrity of products are different, so the stability performance in practical use is relatively average. For example, the dry-wet separation thermal management technology of batteries carried by EU5 is said to be effective in preventing combustion and explosion, but an EU5 exploded in Zhenjiang last September. At the same time, there are also car owners who feedback Ei5 battery failure on the car quality network.

In addition, the brand new has a stronger fan base. As of now,Qin series models have accumulated more than 200,000 fans, and have made remarkable achievements in sales volume, quality and word of mouth.,At this point, the brand-new performance is more ahead of. As a model, last year, some car owners reported on the Internet that it had a nominal battery life of 410 kilometers and actually traveled at full power for 210-220 kilometers. Therefore, in terms of endurance authenticity, brand-new is more reliable.

From the above comparison, we can see that a truly safe new energy vehicle is armed from the inside out to the "teeth", and the basis of this "armed" is the comprehensive technical strength, and the brand-new safety is based on this. It is this technical strength that has been recognized by more peers. It is said that the new factory invested 8.5 billion yuan will be used to produce and cooperate with products under the e platform.

Summary:

Changes in consumer demand after the epidemic will require higher safety, health and intelligence. Choosing a healthier and safer car will become one of the core needs of consumers around the world. At the same time, a truly leading new energy vehicle is that it understands the needs of consumers enough, and the leading comprehensive strength and proper configuration are the real masters. In the field of new energy compact family car, brand-new has really set a benchmark!

SAIC’s Zhiji car reported that it was dissatisfied with Xiaomi because of the comparison of new cars with cyber violence.

  Caixin. comZhiji Automobile, a subsidiary of SAIC, released a new car, benchmarking Xiaomi Automobile in the process. The storm caused by this conference continues. On April 11th, Zhiji Automobile publicly reported that it suffered from organized cyber violence and traffic bullying, which affected the normal business activities and business reputation of the enterprise, and urged relevant departments to severely punish cyber violence.


  On April 8th, Zhiji Automobile released the pure electric car L6. Tamia Liu, co-CEO of Zhiji Automobile, made a speech at the press conference and later became the focus of cyber violence. Tamia Liu said that some employees missed the birth of their children in an effort to "build cars", and some employees sent their young children to boarding schools so that they could meet in a hurry only once a week.


  Since then, there have been a lot of malicious comments in the official Weibo comment area, official live broadcast room and dealer’s live broadcast room of Zhiji Automobile, calling L6 an "orphan car" or a "wife-abandoned car". These messages even encouraged consumers not to buy, saying that "no business, no harm".

The M5 series is a high-performance SUV in the new energy field with no short board in all directions.

   Modern automobile consumers often feel entangled when choosing vehicles, and the fuel consumption of fuel vehicles is high, which is unbearable for wallets; But they are worried about the endurance and performance of new energy sources. Even if I make up my mind to choose a new energy vehicle, I feel confused when I choose which one. After all, as an important travel partner, the endurance, performance and dynamic performance of the vehicle are directly related to the experience of the whole trip. In fact, if you want to solve this problem, you only need to choose a model with excellent comprehensive strength, and the M5 series of Wenjie is a high-quality choice worthy of consideration.

  Endurance, travel without worry

  Whether it’s poetry and distance or daily commuting, the M5 series can meet your needs. Thanks to the intelligent extended-range technology, the comprehensive cruising range of the standard version of the M5 series rear-drive vehicle can reach 1455km when it is fully charged. Normally, a tank of fuel for a domestic fuel vehicle can support a journey of 500-600 km at most, but the data of the M5 standard version of the vehicle can be said to be super doubled. With a cruising range of 1455km, you can go to go on road trip as soon as you want. Whether you start from Beijing and drive all the way west to Xi ‘an to experience the Tang Dynasty, or start from Shanghai and go south to Guangzhou to experience Cantonese morning tea, the M5 series in Wenjie can accompany you across the mountains and seas, and you don’t need to replenish energy to have fun all the time.

  If you don’t like to travel far, you like to feel lucky in your own world. The M5 Smart Driving Edition can help you explore your city with the lowest cost. The pure battery life of the M5 Smart Driving Edition reaches 255km. Even in Beijing, it is more than enough to commute for one week by going back and forth for 30km every day. More importantly, the charging efficiency is high, and it can be charged from 20% to 80% in half an hour. Occasionally, it is absolutely appropriate to go camping for a short distance on weekends and live on pure electricity.

  Full power, popular electric switch

  Compared with traditional fuel vehicles, Wujie M5 series can not only reduce the travel cost for users, but also provide double endurance, and its performance is unambiguous. Take the M5 standard four-wheel drive model as an example. The acceleration time of this car is only 4.4 seconds, which is better than many luxury brand electric SUVs on the market. The biggest benefit of such excellent data performance is super explosive power, which allows drivers to experience the passion of driving a sports car.

  Super explosive power is also related to the dynamic performance of the vehicle itself. The maximum power and peak torque of the M5 standard four-wheel drive model can reach 365kW and 675N·m respectively. In daily life, when the pressure is great, drive this car to release it, feel the speed and passion, relieve the pressure, forget the troubles and regain the passion.

  The strong performance of the M5 series in the world benefits from the blessing of the three-in-one electric drive system of HUAWEI DriveONE. This system adopts the industry’s first precision oil cooling technology, which has a better cooling effect on key components under the same power and torque. The direct benefit is that it can fundamentally improve the power and quietness of the car. If you drive fast at high speed, or speed up overtaking, the power is on call.

  In addition, Wujie M5 version also has HUAWEI DATS dynamic adaptive torque system, which can reduce the pre-driving impulse by 31%, the sloshing convergence time by 46% and the system response time delay to 4 ms.. When driving on potholes or bumpy roads with speed bumps, not only can the car body shake slightly, but it can also stabilize quickly. If the self-driving trip encounters bumpy roads such as mountain roads and gravel roads, it can also pass comfortably, alleviating the discomfort caused by bumps in the car. If you are driving on a road with many curves, this system can help the vehicle to improve the lateral force through adaptive torque adjustment, and the risk of tail flick will be greatly reduced when driving, which is stable and safe.

  The M5 series has brought excellent performance to users in all directions. It can make you say goodbye to all kinds of troubles and enjoy a worry-free driving journey in terms of endurance, power and driving control. If you are eager to travel without worry and enjoy driving, you may wish to try the M5 series. I believe it will bring you a different surprise experience. In addition to the surprise experience brought by the product itself to users, the recent delivery speed is also very surprising. You can pick up the car within two weeks after making a decision. You may wish to experience it in the offline test drive!

Reading | Young People’s "Partner" Socialization

  * This article is the 11th issue of Pindu in 2023.

  I ran into an acquaintance, but I didn’t see him for more than a month and thought he had lost a lot of weight, so I asked him for advice on the secret of losing weight. He told me: "I found some partners to lose weight, ran together and ate fat-reducing meals. Everyone encouraged and supervised each other every day. I didn’t expect the effect to be quite obvious."

  Weight loss partner? Seeing my doubts, my acquaintances told me with a smile that compared with my friends, the utility of "partner" is more clear, and it can be accurately subdivided, such as "meal partner", "game partner" and "gym partner". That is, from the joint participation of something, it ends at the end of cooperation; Highly in tune with a certain field, but emotionally independent. Because we only concentrate on the matter itself, we are both relaxed. The acquaintance said happily: "This time, I lost weight successfully, and’ Zuozi’ contributed a lot. The purpose of getting together is to lose weight. If you lose weight successfully, the mission of’ taking the child’ will be completed, and it will be automatically dissolved. There is no trouble with the relationship. "

  I am a person who seems to have a "flattering personality". Every time I go out with my friends, I always habitually compromise. For example, if I want to stay in a hotel and my friend wants to experience a B&B, then go to the B&B, even though it makes me feel unsafe, I may not sleep well all night. I wanted to taste local specialties, but my friend couldn’t get used to it and asked for a change of fast food, so I stopped insisting and just ate at will. I plan ahead and want to visit more scenic spots, but my friend is tired and prefers to sleep in his room, so stay in his room and play with his mobile phone in another place.

  With the "partner", it is completely different. You are used to staying in a hotel, and I am used to staying in a hotel; You like to eat special food, and I like to try it. You are energetic and want to look around, and I also want to visit all the scenic spots … We are in tune with each other in terms of tourism. If it’s not in tune, then find another one who is in tune, and no one has to accommodate anyone. The original purpose of everyone is to find people with the same hobbies and have a good time. If you are happy, I will be happy.

Reading | Young People's "Partner" Socialization

  I have read Xu Zhimo’s poem: You and I meet in the dark sea/You have yours/I have mine/direction/You remember it/You’d better forget it/The light that shines on each other at this meeting … This poem is very suitable for describing the relationship between partners. After meeting each other, the vast majority of the results are forgotten, but some will remember, and thus further develop.

  Xiaoyuan is an example. When she announced her engagement in a circle of friends, many of her friends were surprised. Everyone knows that Xiaoyuan has always been in fear of marriage, and has declined many people’s kindness to introduce her boyfriend. Why did you suddenly change your mind? Xiaoyuan told everyone shyly that some time ago, she found a "book partner" to read together and exchange reading feelings. This "book partner", like Xiaoyuan, especially likes reading, and they have similar views and have the same view on many things. Because there is no burden of "making friends", Xiaoyuan gets along with each other easily and happily, and unexpectedly discovers the "interesting soul" of each other. It happened that the other party also felt this way, so they naturally developed from "partners" to male and female friends until they "made a positive result."

  In fact, "partner" socialization is a kind of "shallow socialization" above strangers and below friends. This kind of relationship can not only inspire each other, but also cause no extra burden to each other because of the sense of boundary, which is very suitable for busy young people with increasing pressure. If you want to get rid of a person’s loneliness quickly, it is still feasible to find a precise companion.

Nine chapters have come out. Do you know what a quantum computer is?

  On December 4th, Science magazine announced that the "Nine Chapters" of the quantum computer built by China’s research team has achieved a fast solution to the Bose sampling problem, and its calculation speed is faster than the fastest supercomputer at present.One hundred trillion times!

Quantum computer screens the whole network

Netizens are proud and happy about it.

But as soon as I opened the article,

Most friends can only leave a question mark after reading it:

"I know every word, but … …”

"Why is quantum computer so fast?"

Don’t worry!

Here is a "Little White" friendly explanation book.

Let’s put it in layman’s terms.

(This article does not involve any theoretical formula or academic discussion … …

Because Xiaobian is not professional! )

Is quantum computer a computer?

  First of all, what is a quantum computer in one sentence:

  Quantum computer is a kind ofA computer using quantum mechanicsIt can perform some specific calculations more efficiently than ordinary computers.

  So, quantum computer is a kind of computer, but it is not simple."Advanced Edition" computer.And what we now understand as "computer"There is a big difference— — The calculation forms of the two are different.

  For example:

  If the classic computer iscandle, quantum computer islight bulb / third wheelBoth of them are for lighting, but the lighting methods are different and the lighting range is also different. Even if you keep improving candles, you can’t make a light bulb.

  At present, quantum computers use physical systems such as atoms, ions and photons.Different types of quantum computers use different particles.This time, the "Nine Chapters" use photons.

  200 seconds is just a short moment, and 600 million years has already passed.

  How did the "Nine Chapters" quantum computer achieve the "ultra-fast" computing speed through quantum computing?

How does a quantum computer calculate "ultrafast"?

  quantum computer"huge storage capacity"

  First of all, let’s take a look at the storage mode of classical computers and quantum computers ↓

Classic computer

  With a series of0 and 1To store information. Each unit in the series of 0 and 1 is called a bit, and one bit can be set as0 or 1.

quantum computer

  For quantum computersQuantum bitTo store information. Each qubit can not only be set to1 or 0, and can also be set to.1 and 0.

  It can be simply understood that quantum computers store more information per unit.

  What exactly does this mean?

  For example:

  Please think of a number between 1 and 10 and express it with one hand. One hand at a time.Only one number can be expressed.

  This is the fundamental law of storing data in classical computers. It’s just that the computer is faster than our fingers, but one bit of it can only store one binary number.

  However, if you switch to a quantum computer, the way to express numbers will be immediatelyBe subverted.

  For another example, one hand can express 10 numbers. But before the hand reaches out, which number will it represent,Is uncertain.

  This is the storage unit of quantum computer — —Quantum bits,The storage mode of. It stores not specific data, but all possible data.Probability of occurrence.

  Hands are uncertain until they reach out. But qubits take all the numbers that can be expressed with this hand, all of themoverlayTogether. You only use one hand to store 10 different numbers, and the probability of each number appearing is 10%.

  The number that one hand can express is very limited, and it is not a magical thing to store 10 numbers at the same time. But it keeps expanding, and 10 hands and 100 hands can all be used.Superimposed storageIn qubits, this is the power of qubits.

  Quantum computers can therefore carry more content at the same time. Ordinary computer units can only process one bit at a time; Quantum computers can process one "qubit" at a time, thus greatly improving the processing speed.

  The quantum world is essentially parallel.

  Quantum computer not only has powerful storage capacity, but also has powerful parallel computing capacity. Just like turning on a light in a room, light can pass through all the cracks in the wall in an instant. It is this principle that quantum computers can perform high-speed parallel quantum calculations.

  For example:

  Suppose there is a black box with 1000 wire ends sticking out on the left and 1000 wire ends sticking out on the right, but in fact,Only one wire is connected.Dear, excuse me, how do you find this connected wire?

  The answer needs to be tried 1000×1000 times, that is, to1 million timesTo find the answer.

  But it’s much easier to solve this problem with a quantum computer.

The actual operation process of quantum computer

  As we said just now, the storage of qubits is the superposition of all possible numbers. Then from 1 to 1000, it is actually just a group of qubits. In other words, with only one calculation, the quantum computer takes all the possibilities into account at the same time. It can find the connected wire once. Through parallel computing, the efficiency is improved by 1 million times.

  How to calculate this quantum computer, do you see (mei) understand (kan) (dong)?

Why are the "Nine Chapters" so important?

  The appearance of "Nine Chapters" is another leap in the field of quantum science and technology in China, and its significance is multifaceted.

  The first is in the fields of computer, IT and mathematics.If "the superiority of quantum computing" is realized, the computing power on a specific problem far exceeds that of the most powerful traditional computer. In addition, it can also establish quantum communication networks and quantum internet through quantum computers.

  Secondly, in terms of practicality.Quantum computers have a broad space and scope, such as password decoding, big data optimization, material design, etc., which can all be supported by quantum computers, thus solving major national economy and people’s livelihood issues and generating great economic value.As predicted by some scientists, quantum computers will be widely used, and even everyone can use them.

  At the same time, the development of quantum computers,Will bless artificial intelligenceThereby reducing the mistakes in AI application and creating an intelligent system that allows early diagnosis of problems.

  It is worth mentioning that it alsoClosely related to drug research and development.. If quantum computer is used, as long as its calculation speed is 100~1000 times faster than that of classical computer, it is possible to improve the efficiency of screening prodrug molecules to more than 90% and reduce the cost. However, whether the truly effective drug molecules can be obtained depends on the later biological experiments.

  In addition, the fast operation of quantum computers also includesOrdinary but widely used. For example, how to choose the most efficient route for delivery trucks can rely on the help of quantum computers. This is by no means "overqualified".

How far is quantum computing from practicality?

  For the research of quantum computer, international peers in this field have recognized that there are three stages of development:

  The first stage,For some high-complexity specific problems that supercomputers can’t solve, efficient solutions are realized, and in computational science."that superiority of quantum compute"A milestone.

  The second stage,Development of coherent manipulation of hundreds of qubitsQuantum simulatorIt is used to solve some problems with great practical value that supercomputers can’t do (such as quantum chemistry, new material design, optimization algorithm, etc.).

  The third stage,Develop a programmable universalQuantum computing prototype.

  Classical computers have developed from special-purpose computers to general-purpose computers for decades, and now quantum computers are still in the earliest era of special-purpose computers. Even the fastest "Nine Chapters" only crossed the first stage. However, it is undeniable that the appearance of "Nine Chapters" is a great encouragement, and the future can be expected.

Actor wuyue: I’d rather live in a work than live in a hot search.

In the face of He Yun, a "cloudy character" in "Sweeping the Black Storm", wuyue said: "If you don’t dig out snacks, dig up some liver, you can’t do it."

Source: Wen Wei Po (abridged original)

Before "Sweeping the Black Storm", many people called actress wuyue "Lingling", which is the role she created in "My First Half". Wuyue was scolded by some viewers for shutting down Weibo’s comments because of her portrayal of this annoying role.

After Sweeping the Black Storm, many people began to call wuyue "He Ju" or "He Yun". This time, she didn’t play a positive role, but the public praised her rich performance.

The audience’s "no distinction between people and drama" has caused trouble to the actors, but from the perspective of performance, it is also an acting medal awarded to the actors.

She prefers to "live in a work" rather than "live in a hot search". In addition to participating in the voice charm competition variety "Coming to the Scene", she focused on acting: from the TV series "My First Half Life", "Elite Lawyer", "last romance" and "Sweeping the Black Storm" to the movie Better Days, and then to the drama "Dream Like a Dream" … Every role she played broke through the limitation of typology as much as possible.

Better Days

Ling Ling in My First Half Life is an anti-type and anti-routine role. Chen Nian’s mother in Better Days is also a three-dimensional image, and it is difficult to simply define it with the label of "good mother" or "bad mother"; Gu Xianglan in Dream as a Dream is a dusty woman. ……

When filming "Sweeping the Black Storm", wuyue has been immersed in the emotion of "He Yun". In the face of this "role with more cloudy days inside", wuyue bluntly said: "If you don’t dig snacks, dig some liver, you can’t make it."

As an actor, wuyue has proper limit.

At that time, he was admitted to Shanghai Theatre Academy with the first grade in professional courses, and he also won various awards after his debut. However, she admits that she has never really been confident in acting, and she can’t get rid of the sense of panic of newcomers.

Wuyue said frankly that she had been anxious and confused, and even felt that she was "very, very failed, and her life was very gloomy". What helped her in the end was learning and listening.

Once, at work, she took on an overloaded drama contract for fear of "losing". She played five or six plays in continuous shooting with high intensity in one year, which caused her body to "collapse" at the age of 35-thyroid inflammation and had to be nursed back to health.

She stopped filming for a year to recuperate her life. This year’s "stop" also made her discover that it was not so terrible to have no filming and no income for a year.

It is probably because of this experience that she realized: "You should have the ability to recognize something or a situation, which may be an ugly gift from life."

She said: "The profession of an actor is a profession of dealing with the heart. When your heart is out of order, you can see it in your eyes." Wuyue’s determination made her keep her original heart as an actress.

For an actor, most of the time, taking the road that few people walk and looks the most stupid and clumsy is the most competitive, longest and most stable road.

What should some operators do if they start to reduce the frequency of 2G networks and still use 2G mobile phones?

  BEIJING, April 18 (Reporter Wu Tao) Recently, it was reported that China Unicom would close its 2G network. China Unicom issued an announcement in response, and is promoting the frequency reduction of 2G networks in an orderly manner. What is frequency reduction in 2G networks? Will it affect consumers and why?

  Multi-operators start network frequency reduction

  For the frequency reduction of 2G networks, the reporter consulted the three major operators respectively. China Unicom said,The frequency reduction of 2G network can’t be called closing 2G network, because users are still on 2G network, but there is a process of frequency reduction and slimming step by step..

  Some insiders who don’t want to be named said that the gradual frequency reduction of 2G is actually the gradual withdrawal of 2G from the network, and the complete disappearance of 2G base stations means that 2G is completely withdrawn from the network; At present, the three major operators are still in a state where 2G, 3G and 4G networks coexist.

  According to an insider of China Mobile,China Mobile has no plans to quit the network for 2G at present.. As of press time, China Telecom has no reply.

  However, Fu Liang, an independent telecom analyst, revealed in an interview with Zhongxin.com that in fact, all three major operators are doing network frequency reduction work, and China Unicom is still the latest; Among them, China Mobile is doing 3G network frequency reduction.

  Will consumers be affected?

  According to the data released by China Unicom, by the end of February, there were 289 million users in China Unicom, including 187 million 4G users. It is reported that China Unicom’s 2G users account for about 2% of its total users, which means that China Unicom has more than 500 million 2G users.

  Will these users be affected by the frequency reduction of 2G networks? China Unicom said that it willTake various preferential measures, such as replacing mobile phone cards for free, giving away experience traffic, and offering preferential purchase, to assist existing 2G customers to upgrade to 4G networks.In this process, the existing 2G customer service will not be affected.

  Xiang Ligang, an expert in communication industry, believes that the frequency reduction of the 2G network of China Unicom is not affected by the vast majority of consumers.

  Fu Liang believes that it is impossible for 2G users to have no impact at all. It can only be said that it is less affected. After frequency reduction, 2G network coverage may be insufficient in some places, "butFrequency reduction does not mean that the 2G network cannot be used, because there are still 2G base stations.. "

  The reporter noted that, despite the current 4G era, 2G or 3G networks still play a role. Some users said in an interview with Zhongxin.com, "I still feel that the existence of 2G networks is better becauseIn some places, there is no 4G network coverage. When passing through these places, the mobile phone will automatically switch to 3G or 2G networks, and there is still a process of connecting when using it, or it will be disconnected."

  Why do you want network frequency reduction?

  Since there are still users, why do you want to reduce the frequency of 2G networks?

  Fu Liang said that it turned out that2G network occupies some frequency bands, and some frequency bands are scarce, which can be said to be valuable resources. After reuse, it can be used in 4G network construction., which is conducive to improving network quality and network wide-area coverage.

  China Unicom also indicated that the bandwidth resources will be used for higher 4G networks and deployment.

  "In addition, with the decrease of 2G and 3G users, its network capacity is more and more surplus, and its base station and other facilities are increasingly uneconomical to invest in operation and maintenance, which is another reason." Fu Liang said.

  This is true. According to the latest data from the Ministry of Industry and Information Technology, as of the end of February, the number of mobile phone users of the three major operators reached 1.44 billion, of which the total number of 4G users reached 1.03 billion, and 4G users accounted for 71.6% of mobile phone users.

  However, the data of the Ministry of Industry and Information Technology also showed that as of the end of February,The total number of mobile broadband users (namely 3G and 4G users) reached 1.17 billion. This means that there are still 270 million 2G users, which is still a huge number..

  In view of this, Fu Liang believes that it is impossible for the three major operators to shut down the 2G network at once. Network frequency reduction is a gradual process, and 2G users do not have to worry too much.

  "It should also be pointed out that if the equipment used by 2G users supports WCDMA, even if China Unicom shuts down the 2G network, it will still have no impact on them." Fu Liang said. (End)

Wang Zhigang, Minister of Science and Technology: China deploys vaccine research and development according to five technical routes.

CCTV News:The State Council Information Office today (June 7) released the white paper "China Action against COVID-19 Epidemic" and held a press conference to introduce the white paper.

Wang Zhigang, Minister of Science and Technology, in response to a question from a reporter in Reuters, pointed out that since the outbreak of the epidemic, all countries have paid close attention to the vaccine problem. The white paper also includes the related contents of scientific and technological support against epidemic, such as how to combine scientific research such as drugs and vaccines with clinical first-line treatment practice, and how to use big data and artificial intelligence to support against epidemic. As far as the vaccine itself is concerned, judging from the understanding of human response to the epidemic in history, the vaccine is still the fundamental strategy for us to defeat COVID-19 virus at present. All countries put the development of vaccines in a very important position in the fight against COVID-19. But at the same time, we should also see that vaccine development is a very rigorous and complicated scientific activity, which is very difficult and has a long cycle. At the same time, because it is a scientific research, it also has great challenges and uncertainties. Some scientists compare the rigor of vaccine development to an accurately rehearsed dance, rather than an impromptu performance that can be displayed after the curtain is lifted. Therefore, safety, effectiveness and accessibility must be placed in a very important position in vaccine development. Vaccine development has played an important role in human history, but some vaccines have also gone through some detours.

疫苗成功的标志,最重要的是坚持安全、有效和可及。从科学研究上讲,疫苗研制一般要经过病毒分离、实验室疫苗构建、细胞试验、动物试验、临床研究,然后才是规模化生产,最后要经药监部门注册批准才能上市应用。我国按照五条技术路线部署疫苗研发,包括灭活疫苗、腺病毒载体疫苗、重组蛋白疫苗、减毒流感病毒载体疫苗以及核酸疫苗。在疫苗研制过程中和今后的临床试验应用,这两个方面都要加强国际合作。前期我们在整个疫苗研制过程中,都开展了很多国际合作,中国的科学家和其他国家的科学家,都是为了应对疫情,都希望在卫生健康方面为人类命运共同体作出贡献。下一步,中国疫苗如果完成了研制和临床试验后,可以达到应用的时候,我们会认真落实国家主席习近平在第73届WHO大会上的承诺,把它作为公共产品向全球提供。

Today’s beginning of spring | Fu Yang protects the liver, and everything is reborn! Beginning of spring health customs raiders, worth collecting ~

Beginning of spring today.

After beginning of spring, the weather turned warmer, everything revived, and everything was full of vitality.

In the spring, it is not too late to compete for the sun.

When keeping in good health, stay healthy for one year and get sick less!

Beginning of spring custom

Beginning of spring is one of the important traditional festivals of the Han people. On this day, there will be many folk customs and activities.

1. Spring Festival

Floating on the water like a fish.

Beginning of spring health guide

After beginning of spring, the yin cold in winter has not dissipated, and there will be natural phenomena such as late spring cold; At this time, from winter to spring, people’s ability to resist diseases and adapt to the climate is extremely weak, and they are prone to illness.

Therefore, beginning of spring’s health care becomes particularly important, and only by grasping the key points can we get twice the result with half the effort.

Give priority to nourishing liver

According to the nature, the five elements in spring belong to wood, corresponding to the liver. Chinese medicine believes that the liver governs emotions and "anger hurts the liver". Beginning of spring’s health care should focus on regulating emotions, nourishing and protecting the liver, and preventing "hyperactivity of liver fire".

Maintain a happy mood and avoid rage or depression; Through proper outdoor activities, more sunshine and other methods to recuperate emotions, the qi of spring yang can be declared, so as to achieve the purpose of normal operation of human viscera function.

Beginning of spring should pay attention to drinking plenty of water when nourishing the liver. Drinking plenty of water can also promote the secretion of glands, especially digestive glands, pancreatic juice and bile, so as to facilitate digestion, absorption and waste elimination, and reduce the damage of metabolites and toxins to the liver.

In terms of diet nursing, considering the characteristics of protecting the liver and promoting the growth of yang in spring, we should eat more pungent and sweet foods, such as rape, coriander, leek, onion, white radish, chrysanthemum, kohlrabi, Chinese cabbage, celery, spinach and other vegetables.

Beginning of spring nourishing liver and dietotherapy: For people with liver stagnation and qi stagnation, focus on soothing the liver. You can use 10 grams of dried albizzia flowers, 20 grams of fresh products, 150 grams of fresh pig liver, a little salt and soup to drink; Patients with liver disease, such as patients with liver cirrhosis and hepatitis B, should maintain a happy mood, and can adopt dietotherapy to soothe the liver and strengthen the spleen, such as chicken bone grass and crucian carp soup, and avoid fried, hot, fat and indigestible foods.

Pay attention to keep warm and should be "covered in spring"

Chinese medicine believes that spring belongs to wood and corresponds to liver. Therefore, beginning of spring’s health preservation is mainly based on nourishing the liver, and the theory of traditional Chinese medicine holds that "the liver governs emotions" and "anger hurts the liver".

Therefore, the key to nourishing the liver is to keep a good mood and avoid rage or depression. You can recuperate your mood by going out and sunbathing more, so that the qi of spring yang can be declared, so as to achieve the purpose of normal operation of human viscera function.

Proper exercise helps yang qi.

In spring, when the nature is "old", the yang is rising, and everything is sprouting. Just like nature, human qi and blood need to be stretched freely, which requires people to "stay up late and get up early, and be happy with the day". They can take appropriate outdoor sports at the right time of sunshine, breathe fresh air and exercise their bones and muscles. Through proper adjustment, the qi of spring yang can be announced, the metabolic function can operate normally, and the cardiopulmonary function and the human body can be improved. But be careful not to exercise too early or too late, and not to sweat to avoid hurting the yang.

Diet should be sweet and sour.

On Su Wen’s Method of Storing Qi: "The liver governs the spring, … the liver is bitter and anxious, and it is slow to eat urgently, … the liver wants to disperse, and the acute food is pungent to disperse."

After beginning of spring, you can choose some foods that nourish and soften the liver, soothe the liver and regulate qi, such as leek, lobster sauce and coriander. Sweet foods such as jujube and honey water can also be appropriately added, which is beneficial to tonify the spleen and avoid damaging the spleen due to hyperactivity of the liver.

We should pay attention to eating less sour food to prevent excessive liver qi, and the physical properties of the food we eat should be cold. We should use or fast hot food with caution, so as to avoid the occurrence of warm diseases caused by diet promoting internal heat. Drink plenty of water on weekdays, and make tea with chrysanthemum and honeysuckle to clear away heat and dispel wind.

Open the window to breathe and prevent epidemic

After beginning of spring, the weather changed from cold to warm, everything began to recover, and all kinds of pathogenic bacteria and viruses began to grow and reproduce, which was a season with frequent epidemics. As the old saying goes, "A hundred herbs sprout, and an old disease sprouts." In terms of preventive measures, we must first eliminate the source of infection; Second, it is necessary to properly open the door and open the window for ventilation to ensure fresh indoor air circulation, which can also play the role of indoor dust removal and ventilation and reduce the survival of indoor bacteria; The third is to strengthen exercise and improve the body’s defense ability; In addition, wash your hands frequently every day, and pay attention to wearing masks in crowded places.
