  The increasing number of local infections in mainland China has dropped for six consecutive days, and China Communication University has launched online teaching in an all-round way.

  On the 12th, there were 915 new cases of local infection (confirmed+asymptomatic) in mainland China, and the number of local infection was less than 1,000 for two consecutive days, and it continued to decline for six consecutive days. On that day, 188 local confirmed cases were added from 16 provinces: 126 in Sichuan, 11 in Xizang, 10 in Beijing, 8 in Inner Mongolia, 7 in Shandong and 7 in Guangdong, and 3 or less in the other 10 provinces.

  On that day, there were 727 new cases of asymptomatic local infections, distributed in 21 provinces: 199 cases in Xizang, 145 cases in Guizhou, 84 cases in Sichuan, 51 cases in Jiangxi, 39 cases in Guangxi, 34 cases in Shandong, 32 cases in Hubei, 23 cases in Xinjiang, 22 cases in Liaoning and Gansu, 21 cases in Heilongjiang, 19 cases in Inner Mongolia, 13 cases in Shaanxi, and the other 8 provinces each had a single-digit increase.

  Beijing reported on the 13th that from 0: 00 on the 12th to 15: 00 on the 13th, there were 31 newly infected local people in the city, all of whom were related to three campus epidemics. Among the 26 new cases in Chaoyang District, 25 were students from Communication University of China, and 1 was a close contact of the Civil Aviation General Hospital.

  According to the introduction of Communication University of China, the school started online education and teaching in an all-round way on the 13th, and at the same time opened "isolated classroom". At present, 471 courses have been taught online normally. If there are students in the teaching class who can’t attend the class online, the teacher will start recording the meeting during the live broadcast, so that students can make up their studies later.

  Since the outbreak of campus cluster in Changping Campus, beijing university of chemical technology on September 6th, this epidemic has been linked to three schools in Beijing, namely, Changping Campus, beijing university of chemical technology, Middle School Affiliated to Minzu University of China and Communication University of China. A few days ago, Beijing officials said that two epidemics in Changping Campus of beijing university of chemical technology and Middle School Affiliated to Minzu University of China were in the final stage, and the epidemic situation in Communication University of China was generally controllable.

  The epidemic situation in Chengdu, Sichuan Province is improving, and the social control is strengthened in Neijiang District 4.

  On the 12th, there were 126 confirmed cases (including 29 asymptomatic cases) and 84 asymptomatic infected cases in Sichuan Province, which still involved Chengdu (18+26), Neijiang (49+11), Yibin (17+12) and Luzhou (1+9).

  The Chengdu Municipal Health and Health Commission reported on the 13th that the increasing number of infected people in Chengdu showed an upward trend from August 26th, and then gradually declined after reaching the peak on the 29th. Since September 8, the number of cases has been less than 100, and it has dropped to less than 50 in the past two days. The overall epidemic situation is improving. At present, Chengdu’s action of clearing and tackling difficulties has been steadily advanced, but there are still cases detected in the society every day, and the prevention and control of the epidemic situation cannot be relaxed.

  While the epidemic situation in Chengdu is getting better and better, the epidemic situation in some parts of Sichuan is not optimistic. On the 12th, there were 60 new cases of local infections in Neijiang City, surpassing Chengdu to become the region with the largest number of new local infections in Sichuan Province that day.

  According to the report of Neijiang City, the current epidemic in this city began on September 8th. The first case was found when the patient went to the fever clinic on his own initiative. Its gene sequencing result was Omicron mutant strain BA.2.76, which is the main epidemic strain in Sichuan Province and surrounding provinces. However, this case has no recent history of living in other cities, and the source of the epidemic is unknown.

  On the evening of the 12th, Neijiang City issued a notice saying that the current epidemic situation in the city is severe and complicated. In order to resolutely block the virus transmission chain, Neijiang City decided to continue to strengthen the social epidemic control in four districts of the city from 0: 00 on September 13th.

  The epidemic situation in Sanya has been effectively controlled, and the epidemic situation in Urumqi has entered the stage of clearing the tail.

  On the 12th, there were 2 new cases of asymptomatic infection in Hainan province, including 1 case in Sanya and 1 case in Danzhou. From August 1st to September 12th, Hainan Province reported a total of 20,712 cases of local infection, including 15,646 cases in Sanya.

  Sanya City reported on the 13th that a new asymptomatic infected person was found in the isolation control point on the 12th. Since September 5th, there has been zero social increase in this city for eight consecutive days, and the number of new infections every day is in single digits, and the epidemic situation has been effectively controlled. According to the current epidemic situation, after comprehensive judgment, Sanya City decided to lift the temporary static management of some areas in the central city.

  On the 12th in Xinjiang, 3 new cases were diagnosed locally and 23 cases were asymptomatic, and the number of local infected people increased to no more than 30 for 6 consecutive days. As one of the key areas of the current epidemic in Xinjiang, Urumqi added 3 cases of local diagnosis and 6 cases of asymptomatic infection on the 12th.

  According to the report of Urumqi, in recent days, the number of infected people in the city has remained in single digits, and the epidemic situation in the city has entered the stage of sweeping the tail and clearing it. At present, the focus of Urumqi’s work has gradually shifted from epidemic prevention and control to promoting post-epidemic economic recovery and development. Low-risk areas have gradually resumed social mobility in an orderly manner, and employees of enterprises and institutions have successively started the "two points and one line" work mode of resuming work and production.

  The number of infected people in Guiyang, Guizhou is still at a high level, and silent management is implemented in Hebei and Hebei.

  On the 12th, there were no new confirmed cases in Guizhou province, and 145 cases of asymptomatic infection were newly added, including 118 cases in Guiyang. As of 24: 00 on the 12th, a total of 491 local infected people (16 confirmed cases and 475 asymptomatic cases) were reported in Guiyang.

  Guiyang reported on the 13th that at present, the number of newly infected local people in Guiyang is still running at a high level, and the situation of epidemic prevention and control is still severe and complicated. Only by taking the most powerful, effective and accurate measures, implementing district-level management and controlling risks to a minimum is the key to winning.

  On the 12th, there were no new confirmed local cases in Hebei Province, and 3 new asymptomatic local infected people were reported in Shuangluan District of Chengde City, all of which were found in centralized isolation points. As of 24: 00 on the 12th, there were 12 confirmed cases and 142 asymptomatic infected people under medical observation in Hebei Province.

  Shuangluan District of Chengde City issued a notice on the 12th, saying that from 18: 00 on the 12th to 18: 00 on the 16th, temporary silent management will continue to be implemented in the whole area, and all personnel will be tested for nucleic acid according to the principle of "no one is missing, no one is missing". During the temporary control period, all personnel stay indoors and remain silent.

  Sanhe city, Hebei Province, reported on the 13th that in the early morning of the same day, one person who was closely contacted by a Beijing investigation team had a positive nucleic acid test, and several other people exposed to epidemic-related places in Beijing had action tracks in the city, which was a risk of epidemic spread. Therefore, sanhe city decided to conduct a four-day silent management for the whole region from 6: 00 on the 13th, and carry out four rounds of full-time nucleic acid testing continuously. (End)

This concept has been mentioned again and again by the supreme leader in three important diplomatic activities.

On April 26, the top leader delivered a keynote speech at the opening ceremony of the second "Belt and Road" international cooperation summit forum;

On April 28th, the Supreme Leader delivered an important speech at the opening ceremony of the 2019 Beijing World Horticultural Exposition in China.

On May 15th, the Supreme Leader delivered a keynote speech at the opening ceremony of the Conference on Dialogue among Asian Civilizations.

Three important diplomatic activities and three different themes all mentioned the same idea — — Building a community of human destiny. From the community of destiny between countries, the community of destiny within the region, and the community of destiny of mankind, the Chairman of the Supreme Leader spoke earnestly and thought long-term, and repeatedly expounded China’s proposition in the light of the overall situation of China’s development and international cooperation, contributing China’s wisdom to the world and providing China’s plan.

On April 26th, the top leaders and foreign leaders attending the opening ceremony of the second "Belt and Road" international cooperation summit forum stepped into the venue together.

Always say that manufacturers cut corners? They also fight for a better user experience.

Many users will worry about the workmanship of buying mobile phones. After all, mobile phones are not cheap objects, and the purpose of buying mobile phones is not to disassemble and inspect the workmanship. As an editor who often does disassembly columns, the mobile phone manufacturers who can live to this day are unambiguous in their internal work for the actual user experience. 315 "International Consumer Rights Day" is coming. Today, we will take stock of what efforts manufacturers have made in mobile phone work for user experience.
Whether the protection is in place is the standard to test the internal work of mobile phones.
The internal protective measures of mobile phones are mainly to protect internal components from vibration, dust, water vapor and electromagnetic interference. The precise components in the mobile phone are fixed on the motherboard in the form of soldering, and all the important components on the mobile phone motherboard realize various complex operation instructions on the mobile phone through BTB socket and printed circuit with other components.
Excellent internal workmanship is indispensable for BTB protection.
BTB seats are all equipped with protective mobile phone motherboards.
BTB cradle is the "joint" connecting other components on the mobile phone motherboard, and the fineness of BTB protection can measure the workmanship of a mobile phone to a certain extent. The protection of BTB socket mainly guarantees two points, one is to ensure the connection between BTB socket and other FPC (flexible printed circuit board), and the other is to strengthen the connection between BTB socket and soldering to some extent. Tin is a very active metal, which is prone to oxidation failure, and the protection of BTB ligand slows down the tin oxidation reaction on printed circuits to some extent.
How to prevent dust and water is a big problem.
The selling point of some mobile phones is to promote IP68 dustproof and waterproof, of which 6 is dustproof and 8 is waterproof. Many people think that waterproof and dustproof is just to prevent contact with water and dust, but in fact it is not just that. We should know that the whole mobile phone is not completely closed, and the Type-C interface, SIM card slot and power button are all openings connected with the internal components of the mobile phone.
Waterproof rubber ring in red frame
It is the simplest to set waterproof for SIM card slot, just set waterproof rubber around the card slot, and set a waterproof rubber mold in the middle frame of the mobile phone. The dust-proof and water-proof measures such as earphones and speakers are to set a layer of filter screen around the speaker, and a waterproof rubber is set around the filter screen, so that air can circulate and water can be prevented from entering. At the same time, the speaker and microphone themselves are waterproof, so water entering the speaker will not cause too much harm to the mobile phone.
The waterproof of 3.5mm earphone interface and charger is mainly realized by setting a layer of rubber waterproof inside the mobile phone. At the same time, we should pay attention to that water is easy to remain inside the components, and most of the water contains many impurities. In these key dustproof and waterproof parts, manufacturers will set waterproof coatings.
How to shield electromagnetic interference in a land of land and gold?
Conductive foam for cushioning and shielding electromagnetic interference
The main board of mobile phone is short of land and gold, and the distance between components is very close, which inevitably leads to electromagnetic interference between different components. In order to solve the electromagnetic interference of components, mobile phone manufacturers mainly use shielding cover, copper foil and conductive foam. Many friends don’t quite understand the function of point foam. Conductive foam mainly plays a shielding role, reducing the interference between different components, and at the same time, it can also play a role in buffering and damping.
Waterproof, dustproof, shockproof and reducing electromagnetic interference are only the basis for the normal operation of the mobile phone. The most critical part of the user experience is to give full play to the performance of the mobile phone hardware, which is inseparable from the internal heat dissipation of the mobile phone.
02 heat dissipation is an important consideration for mobile phone workmanship.
The improvement of mobile phone performance brings greater absolute value of heating density; 5G signals require more antennas and also bring heat; Closer arrangement of components; At present, the mainstream glass case ….. all of the above put forward new requirements for the heat dissipation of mobile phones. Mobile phone manufacturers have introduced unique technologies such as graphene heat dissipation, VC vapor chamber and liquid cooling heat dissipation on the basis of the traditional metal middle frame.
Graphene heat dissipation
Graphene heat dissipation is the most widely used heat dissipation technology in mobile phones. Graphene heat dissipation is mainly a heat dissipation technology developed by using the excellent thermal conductivity of graphite crystals. The advantages of graphite crystal as a heat dissipation material are: good high temperature resistance, difficult deformation when heated, strong plasticity and light weight, and the heat dissipation shape can be changed according to requirements.
Graphene heat dissipation
It can be said that the above advantages of graphene can perfectly handle the heat dissipation of mobile phones. The heat dissipation coefficient of graphene is 2 to 5 times that of copper, but the density is only 1/10 to 1/4 of that of copper, which is convenient for the weight control of mobile phones. Graphene is easy to process, and manufacturers can make the shape of graphene according to the heat dissipation size; Graphene can shield electromagnetic waves and solve the problems of heating of mobile phone components and electromagnetic interference inside the mobile phone; At the same time, graphene does not deteriorate with the service life.
Graphene is not only used in smart phones, but also in electronic devices such as tablets, PCs and laptops.
Liquid cooling heat dissipation
Liquid-cooled heat dissipation exists in the mobile phone in the form of heat pipe, which transfers heat by using the changing characteristics of vaporization and liquefaction in the process of liquid heat transfer.
Liquid cooling heat dissipation principle
The working process of liquid cooling heat dissipation is as follows: the condensate is heated into steam → the steam flows to the condensation end under pressure difference → the steam is exothermic and condensed into liquid at the condensation end → the condensate at the condensation end returns to the evaporation end with the help of capillary force of the wick. Water is commonly used as the coolant in liquid cooling heat dissipation of computer, and the requirements of mobile phone are higher than those of PC, and oily materials are commonly used as the coolant.
Inside the red frame is a liquid-cooled radiator tube.
The advantages of liquid cooling heat dissipation are long service life and flexible arrangement. The liquid-cooled radiator tube will not produce mechanical or chemical degradation after permanent packaging, so the typical service life is about 20 years; Liquid-cooled heat dissipation can be placed in any position where heat dissipation is needed, and at the same time, the liquid-cooled heat dissipation pipe will absorb the heat in the distance and then dissipate heat.
VC vapor chamber
The principle of VC vapor chamber is the same as that of liquid-cooled radiator, but VC vapor chamber can radiate heat in four directions, so the heat dissipation effect is better.
The manufacturing process of vapor chamber is that wick structures are arranged in the upper and lower copper bases, and then brazed, filled with cooling liquid and sealed and brazed. Vapor chamber will have different designs according to the size of different components, and the manufacturing process is complicated and the manufacturing cost is high. Generally, VC vapor chamber is mostly used for high-end mobile phones or high-performance mobile phones.
In the red box is VC vapor chamber.
In addition to the above cooling methods, mobile phone manufacturers will also apply silicone grease to the corresponding position of SoC to transfer heat in a fast and direct way. The above heat dissipation does not exist alone in mobile phones, but often appears in combination of various technologies. It can be said that the development of heat dissipation technology has greatly improved the performance of mobile phones.
The heat dissipation technologies mentioned above do not exist singly in the mobile phone, but are often the combination of two, three or even four heat dissipation technologies, which greatly reduce the heat generation of the heavy load of the mobile phone. While mobile phones meet the performance bottleneck, manufacturers have added more structures to improve the user experience.
Differentiated workmanship is only for better user experience.
In the case that the shape of mobile phones has not changed, manufacturers have made great efforts under different structures. Some of these differences are to improve battery life and charging speed, some are to improve the user’s experience, and some are to reuse the internal volume of mobile phones as much as possible.
OPPO dual-cell battery
For example, in order to improve the charging and discharging efficiency of the battery, OPPO has a dual-cell battery.In order to achieve higher power fast charging, OPPO found that the safety risk of filling one 4000mAh battery with fast charging technology is much higher than that of filling two 2000mAh batteries. In the safe future, OPPO adopts the dual-cell mode, which can provide the best charging efficiency, and can also use the charge pump to halve the voltage of the dual-cell when discharging, thus obtaining better charging and discharging efficiency.
Real disassembly linear motor
In order to get a more exquisite touch feeling, the current flagship mobile phone is gradually equipped with a linear motor.The principle of linear motor is similar to that of pile driver, which directly converts electric energy into kinetic energy through the linear motion of vibrator. The advantage of linear motor is that it has fast vibration response speed, controllable vibration frequency and amplitude, and can debug complex vibration feedback, but it is bulky, difficult to design, complex to debug and expensive.
Stacked motherboard design
As we all know, the improvement of mobile phone performance and the support for 5G make it inevitable for mobile phones to integrate more and more components. Most manufacturers adopt the scheme of plug-in baseband to increase the area of mobile phone motherboard by 20-30%. Obviously, this is unacceptable for the inside of a mobile phone with an inch of land.Most manufacturers increase the utilization rate of mobile phone motherboards by stacking motherboards.
Write it at the end
The internal work of mobile phones is a huge and complicated project. From the above processes, we can see that the quality user experience brought by mobile phones requires not only the manufacturers to do a good job in the dust-proof, waterproof and shockproof aspects of mobile phones, but also to work hard on heat dissipation and differentiated work, which can be felt by users. It can be said that the mobile phone giants in the market attach great importance to mobile phone work, and the manufacturers have also invested enough money in the work of mobile phones.

Iqiyi limits the definition of TV projection screen? 4K is gone, only 480P, and users can’t accept it!

Price increases, restrictions on the number of login devices, and restrictions on screen projection … The adjustment actions of video platforms in terms of members are becoming more and more intensive, and almost every adjustment will cause users to vomit.

The latest controversy comes from iQiyi. Recently, some netizens found that when Iqiyi Gold members cast screens, they can only choose 480P with low definition, instead of supporting 4K. This adjustment has caused users to vomit widely.

In this regard, a legal person told the reporter of Securities Times E Company that when the video platform really needs to adjust the user agreement, it should fully consider the experience and opinions of consumers and pay attention to the rationality and fairness of the content of the agreement adjustment.

Iqiyi limits the clarity of projection screen?

It is a common practice to open a video platform APP member and project a screen to play on TV. Recently, however, many users have found that the screen definition of iQiyi Gold members has been restricted.

Previously, the Gold Member TV projection screen could support up to 4K resolution, but now it can only choose 480P resolution. Higher definition requires platinum membership.

Because of the low definition of 480P, it is almost impossible to watch it on a big screen TV. Some users said that this basically means that the screen projection function of gold members disappears.

Gold membership is the most basic membership mode of iQiyi. Judging from the provisions of the membership agreement, the gold member itself does not include the right to use the TV.

Iqiyi APP shows that its gold members’ mobile phones, computers and tablets can be used, excluding TV. Platinum members focus on the "big screen+small screen" viewing function, which is actually gold members+TV rights, and can be watched on mobile phones, tablets, computers, TVs and other terminals. More advanced and more expensive Star Diamond members can be used in more terminals.

The Iqiyi membership agreement also explicitly mentions that the membership rights enjoyed by each member type can only be used on the equipment terminals to which the VIP membership type applies, and cannot be used across terminals. If the gold VIP member is opened, the membership rights can be used on the computer/mobile phone /Pad side, but not on the TV side and the projection screen.

However, before, Iqiyi Gold members supported the projection of the screen to the TV terminal with high definition, and many tutorials were also provided in the APP and website to guide users to use the screen projection. Only some copyrighted content has screen projection restrictions, and there will be patch advertisements before screen projection.

After gold members restrict screen projection, users need to spend more money if they want to use it happily on TV. The original price of iQiyi gold VIP is 258 yuan/year and 30 yuan/month, while platinum VIP needs 388 yuan/year and 50 yuan/month.

In addition to iQiyi, the basic membership rights of other video platforms also exclude the TV side. For example, the most basic VIP members of Tencent Video can only be used on mobile phones, computers, tablets and intelligent hardware, except TV.

On the basis of VIP membership service, Tencent Video Super Video VIP members increase the rights and interests of TV users. If you want to play it on TV, you need to buy this level of VIP.

User dissatisfaction: will the agreement be changed if it is changed?

Since last year, several major video platforms have frequently caused user dissatisfaction by adjusting member prices and restricting login terminals.

For the adjustment of member price, at least the users who have purchased members are basically unaffected. However, limiting the number of device logins and the clarity of screen projection will affect all users, including existing members, which is also the reason for users’ dissatisfaction.

"This is just like I spent 8,000 yuan on a haircut card, saying that I can enjoy a 30% discount on the original price. Then after a few months, he adjusted the price, and the original price became more expensive. I think the 30% discount card with a recharge of 8,000 is the same." Some users spoke to reporters.

Some users also said that when purchasing members, they can choose the clarity of the projection screen, but now they can’t, and they will change it if they say it is changed. Any adjustment of the platform shall be notified in advance, and shall take effect at least from the next purchase of members.

However, if you look carefully at the membership terms of the video platform, you may find that the video platform has actually stipulated the adjustment of membership rights.

As mentioned in Tencent Video, the application scope of its membership service is constantly increasing and adjusting with the expansion and change of cooperation, subject to the actual situation when users enjoy the membership service.

It has the right to adjust all or part of the service content of Tencent Video Series members (including but not limited to changing, canceling, reducing, increasing the broadcast progress of video content, stopping broadcasting or paying extra for on-demand, payment restrictions, etc.) according to legal provisions and policy changes, requirements of copyright owners, operational needs and user needs.

(Detailed regulations of Tencent Video on terminals that members can use)

There is a similar expression in the Iqiyi agreement. Adjusting the rights and interests of members, service types, membership packages, rights and interests details, adding or changing the content of extra payment, and optimizing some product functions are all covered by the relevant provisions.

Aiqiyi said that Aiqiyi will notify the above-mentioned adjustment on the service page or in other reasonable ways, and at the same time, Aiqiyi will try to minimize the impact of the above-mentioned adjustment on the rights and interests of existing members.

Legal Person: Adjustment should pay attention to fairness.

If the agreement has been agreed, can the video platform adjust the terms at will?

In this regard, Lawyer Si Binbin of Beijing Tao ‘an Law Firm said in an interview with a reporter from Securities Times E Company that the User Service Agreement of the video platform belongs to a common Internet service format contract. There are two possibilities for the video platform to unilaterally modify the terms without consultation.

"If the content of the revised terms is reasonable, such as the reasonable adjustment of the content of commercial services, which does not substantially harm the rights and interests of users and belongs to the independent management right of the platform company, the law does not prohibit it. If the content of the unilateral modification clause restricts the user’s right to choose and know, it is an unfair clause that is unilaterally inclined to the video platform, and it also infringes on the fair trading rights of consumers, and may even be suspected of fraudulent consumption. " Si Binbin said.

Si Binbin introduced that format contracts and terms are widely used by video websites because they are pre-drafted, non-negotiable and reusable, which can meet the requirements of efficient trading of video websites.

"Although the format contract is also subject to some legal restrictions, such as the platform’s suggestive obligations to users, the platform cannot unreasonably exempt or reduce its responsibilities, aggravate users’ responsibilities, and restrict users’ main rights. However, the terms are drafted by the operators in advance, and consumers have no room for substantive negotiation, which aggravates the abuse of standard terms. "

Si Binbin suggested that in administrative supervision, the "user agreement" provided by large Internet platforms can be independently reviewed by a third party (such as consumer associations) in advance to avoid obvious unreasonable clauses in the "user agreement" and make it time-consuming and laborious for consumers to defend their rights afterwards.

"In addition, when the video platform really needs to adjust the user agreement due to business content and market operation needs, it should fully consider the experience and opinions of consumers and pay attention to the rationality and fairness of the content of the agreement adjustment." Si Binbin said.

Australia legalized same-sex marriage in Australia through the same-sex marriage bill.

  Xinhua News Agency, Canberra, December 7 (Reporter Zhao Bo) The Australian House of Representatives officially passed the same-sex marriage bill on December 7, and same-sex marriage was officially legalized in Australia.

  Earlier, the Australian Senate passed the same-sex marriage bill on November 29 with 43 votes in favor and 12 votes against.

  After the House of Representatives passed the same-sex marriage bill, Australian Prime Minister Turnbull said on social media that "it is time to implement a wider marriage, with more commitment, more love and more respect, and marriage equality has been passed."

  Australian Attorney General George Brandis issued a statement saying that the legalization of same-sex marriage reflects the equality of marriage in Australia and is also a major reform of the Australian marriage law. Brandis said that from December 9, any same-sex couple in Australia can submit an application for marriage, and after passing the examination, they will become legal couples and be protected by the Australian Marriage Law.

  In the Australia-wide postal referendum held from September to November this year, more than 60% of the people voted in favor of amending the marriage law. The number of people who participated in the postal referendum exceeded 12.72 million, and the turnout rate reached 79.5%. The votes in favor of amending the marriage law and legalizing same-sex marriage accounted for 61.6% and the votes against it accounted for 38.4%.

Today and tomorrow, rainfall in Sichuan, Shaanxi and other places will develop, and the hot and humid weather in the south will continue.

  Cctv newsAccording to the news of China Weather Network, the precipitation in China will mainly appear in the eastern Sichuan Basin and the eastern part of Northwest China today and tomorrow (May 29th to 30th), and the local rainfall will be fierce. Affected by the strong northward subtropical high, the hot weather in Jiangnan and South China continues, and the relative humidity of the air is high, the lowest temperature rises, and the body feels sultry and unbearable. The public should pay attention to heatstroke prevention.

  The center of gravity of rainfall shifted to the west, and the rain in Sichuan, Shaanxi and other places was fierce

  Yesterday, the strong precipitation was mainly concentrated on the north side of the subtropical high, and the local rains in Jianghuai and eastern Sichuan Basin were fierce, accompanied by strong convective weather. Monitoring shows that there are scattered heavy rains or rainstorms in southeastern Shaanxi, northwestern Chongqing, eastern Henan, northeastern and central Anhui, northwestern and central Jiangsu, and heavy rains in Shangqiu, Henan, Xuzhou, Jiangsu, Huaibei, Suzhou and Hefei, Anhui; There are 8 ~ 9 thunderstorms and strong winds in central Jiangsu.

  Today and tomorrow, the rainfall in the Jianghuai and Huanghuai areas will gradually weaken, and the center of gravity of rainfall will shift to the west. The rainfall in the eastern part of the northwest region and the eastern part of the Sichuan Basin is strong, and there are heavy rains in the local area. At the same time, the rainfall in North China and other places has developed one after another, and it is generally dominated by small to medium rainfall.

  The Central Meteorological Observatory predicts that today, there will be moderate to moderate rain in most parts of Huanghuai, Jianghan, Jianghuai, northern Jiangnan, eastern Southwest and northern China, central and western Inner Mongolia, southeastern northwest, Xinjiang along Tianshan Mountain, southern Yunnan, Hainan Island and Taiwan Province Island, among which there will be heavy rain or rainstorm (50-80 mm) in parts of eastern Sichuan, northern Chongqing, southwestern Shaanxi and western Henan.

  Affected by continuous heavy rainfall, the meteorological risks of geological disasters and mountain torrents in Sichuan, Chongqing, Shaanxi and other places are high, so the local public should pay attention to prevention. Generally speaking, in the next ten days, the precipitation in Sichuan Basin, Guizhou, eastern Yunnan and southeastern part of northwest China will be more than normal, especially in the border area between northeastern Sichuan and Shaanxi, so it is necessary to strengthen the prevention of secondary disasters.

  The high temperature weather in the south continues to develop, and the temperature in South China and other places is high, and the sultry weather is intensified.

  In terms of temperature, with the strong northward subtropical high, the hot weather in the south continues to develop today, and some areas in Jiangnan, South China, Jianghan and Yunnan have high temperatures. Among them, even if the area in the south of the Yangtze River does not reach the 35℃ high temperature line, the highest temperature will generally reach 32~33℃, and the lowest temperature may be around 25℃. In addition, the relative humidity of the air is relatively high, and the body feels very stuffy, so you can experience a mild summer or a severe summer in advance.

  However, starting from tomorrow, the high temperature in the south of the Yangtze River will converge, and the maximum temperature will drop to about 30℃. South China is still in the "protracted war" of high temperature. In the coming week, Guangzhou, Nanning, Fuzhou and Haikou may experience high temperature for 3-4 consecutive days, and the lowest temperature is above 25℃, which will make them feel like "steaming sauna" almost all day. The local public needs to do a good job in heatstroke prevention and cooling.

  In the north, due to the influence of cold air and frequent rainy weather, the temperature will fluctuate in the coming week, and the overall temperature will be lower than normal. In big cities, the highest temperature in Beijing, Tianjin and Shijiazhuang on the 30th is only about 25℃, which makes people feel comfortable.

Optimizing the business environment is not the best, only better.

  In the face of many challenges brought by changes in the external environment to China’s development, as well as many shortcomings and deficiencies still existing in the business environment, we must make great efforts to promote the optimization of the business environment in depth. The various reform measures introduced depend on whether the procedures can work, the possible negative effects and overlapping effects of policies and measures should be considered, and enterprises and the masses should really get benefits.

  According to the Business Environment Report released by the World Bank recently, the ranking of China’s business environment in the world jumped from 78th last year to 46th, and it entered the top 50 in the world for the first time. According to the report, in the past year, China has implemented a record number of reforms to improve the business environment for small and medium-sized enterprises, ranking among the top ten in the world this year.

  The improvement of the business environment is driven by reform. In recent years, China has fully implemented the national unified negative list system for market access, giving market players more initiative; Push forward the reform of "separation of licenses" throughout the country and reduce the start-up time of enterprises; "Internet+government service" opens up isolated islands of information, allowing more people to "run the internet more and run the road less"; Fully implement "double random and one open" supervision to improve the efficiency and fairness of supervision; On the basis of vigorously reducing taxes and fees in the past few years, this year, a number of measures have been intensively introduced, such as reducing the value-added tax rate and retaining tax rebates. It is estimated that the tax burden will be reduced by more than 1.3 trillion yuan in the whole year … …

  The continuous optimization of the business environment makes the market more dynamic and attractive. In the first three quarters, there were a large number of new players in China’s market, and the number of newly registered enterprises exceeded 5 million, with an average daily number of more than 18,000. In the first three quarters, 45,922 foreign-invested enterprises were newly established in China, a year-on-year increase of 95.1%; The actual use of foreign capital was 636.7 billion yuan, a year-on-year increase of 2.9%.

  The results are gratifying, and we still need to stay awake. In the face of many challenges brought by changes in the external environment to China’s development, many shortcomings and shortcomings still existing in the business environment, and the strong expectation of enterprises to reduce burdens, we must make great efforts to promote the optimization of the business environment in depth.

  The intensity is bigger. At present, Chinese enterprises are facing multiple pressures such as transformation and upgrading, rising costs and intensified competition, and the changes in the international economic environment have brought troubles to some enterprises. Under this circumstance, it is even more necessary to increase tax reduction and fee reduction, release more policy dividends, and let enterprises have a real sense of gain. While ensuring that the established policies are implemented to the letter, we should promptly study specific measures to further reduce corporate tax burden and social security rates, further clean up and standardize administrative fees, increase the efforts to clean up and rectify intermediary service fees, and help enterprises go into battle lightly.

  There should be more innovation. There are differences in business environment in different places, so it is necessary to be based on reality, innovate ideas, methods and countermeasures, act positively and be brave in innovation, and form an atmosphere of competing to optimize the business environment. The General Office of the State Council has previously informed some places of the typical practices of optimizing the business environment, such as the reform of the commitment system for enterprise investment projects, the reform of joint acceptance within a limited time, the reform of "one photo with multiple addresses" and "one license with multiple addresses", and the implementation of the "one-stop sunshine price" list. All localities should continue to innovate, constantly explore new methods, and use scientific and efficient "one thousand ways" to seek "exquisite" business environment.

  Look farther. At present, countries are competing to create a more relaxed and convenient business environment to enhance their national competitive advantage. We need to relax market access, improve the system of qualified foreign investors, improve the level of investment facilitation by benchmarking international standards, and protect the legitimate rights and interests of foreign investors. On cross-border trade, the World Bank report praised China’s "single window" construction. Of course, we still need to look at the world and the future, promote a new round of reform and opening up, and further improve the level of rule of law, internationalization and convenience of the foreign investment environment.

  The measures should be more practical. To optimize the business environment, we should not only focus on the internal evaluation of the government, but also focus on the actual feelings of enterprises and the masses. The various reform measures introduced depend on whether the procedures can work, the possible negative effects of policies and measures and the overlapping effects between them should be considered, and enterprises and the masses should really benefit. Government departments should strengthen the service spirit of "shop assistant", listen to the needs of enterprises, especially small and medium-sized enterprises, private enterprises and difficult enterprises, and help them solve difficult problems.

  At the symposium of private enterprises held a few days ago, General Secretary of the Supreme Leader put forward six policy measures: reducing the tax burden of enterprises, solving the problem of difficult financing for private enterprises, creating a level playing field, improving the policy implementation mode, building a pro-fresh relationship between government and business, and protecting the personal and property safety of entrepreneurs, which injected strong confidence and motivation into the healthy development of the private economy, and also pointed out the clear direction and put forward higher requirements for the next step of optimizing the business environment.

  Optimizing the business environment is not the best, only better. On this endless road, we should continue to struggle forward.

"Brush face" has been out. The latest unlocking method "Brush heart" has been vacated.

 

 

  Still talking about "brushing your face"? It’s already "out" Not long ago, a brand-new biometric system — — The cardiac activity cipher system came out quietly. As a new member of the biometric system family, the latest unlocking method relies on everyone’s unique heart activity, so users don’t have to endure the original complicated password system and directly "brush their hearts". The next generation of identification system directly uses the "heart" to unlock the lock. In the future, you deserve it.

  Text, map/Guangzhou Daily All-Media Reporter Huang Wei

  [New Discovery]

  "Brush face" has been born out of "brush heart"

  For users, data security is becoming more and more important. In addition to passwords, different biometrics are now introduced to increase user security, such as fingerprints, face recognition and voice. Some time ago, face-brushing technology was once hotly discussed. Apart from unlocking the mobile phone, we can feel the "sense of technology" brought by the face recognition system, whether it is the ticket inspection recognition of the railway system or the identification of the marathon runners.

  While experiencing the convenience of "brushing your face", everyone keeps asking "questions". For example, compared with the fingerprint recognition function, although the face recognition system looks more accurate, it is often unable to be accurately recognized because of subtle changes in external characteristics. So people who love to study constantly challenge the "face brushing" technology with photos, twins and 3D models of faces. The power of science and technology always pushes the waves ahead, and the next latest biometric identification may be better, that is, "heart identification."

  Three years ago, a Canadian research company developed a biotechnology wristband, which can identify the wearer by scanning the heart activity and unlock the use of daily necessities. This special wristband has two sensing areas, one is inside the wristband and is in direct contact with the wrist skin; The other is outside the wristband. When the wearer puts his finger on an external sensor, the wristband will scan the heart activity to confirm the user’s identity, just like an ECG device.

  It sounds like a sports watch or bracelet that we can measure the heart rate now. From fingerprints, irises to voiceprints, from "brushing face" to "brushing brain" to "brushing heart", it is undeniable that human biometric data has unparalleled particularity, and the biometric field has been very lively in recent years. However, when you think that this is the whole of "heart recognition", the more powerful is yet to come.

  Identification system capable of continuous monitoring

  The biotechnology wristband developed by Canadian research company mainly uses electrodes to measure electrocardiogram, so it needs direct contact with human body, which is inconvenient to use. Not long ago, researchers at the University of Buffalo spent three years creating a more convenient identification system — — Without direct contact with the human body, we can identify the identity by analyzing the geometric characteristics such as the shape and size of the heart and the fluctuation of the heart by radar long-distance scanning. The researchers hope that this device can use the shape and size of the heart and the beating frequency as signs to identify individuals. It is worth mentioning that after detecting the user’s heart, this system will continue to monitor to ensure that no one else breaks into the equipment or system that the user needs to guard.

  The security of "heart recognition" lies in that it can be further enhanced by constantly monitoring users, such as automatically sensing and locking when users leave; The advantage is that it is not easy for others to know how you unlock it, because everyone’s heart is unique. The advantages of this identification system were also discovered by the research team of the State University of New York at Buffalo. They created a system to evaluate the user’s heart by using Doppler radar, and analyzed the changes of the heart in different movements through the microwave signals bounced from the heart. The whole analysis process only took about 8 seconds. Using the collected data, such as the shape, size and moving mode of the heart, we can create a unique identity for the user.

  Using a unique heart to create a unique identity ID sounds very "existential". However, while we admire the progress of science and technology, we must also realize that how safe biometrics can be, how dangerous it can be. Can "heart recognition" really stop us from being "recognized" from now on?

  [Expert voice]

  Biometrics will gradually

  Replace bank password

  In this world, there are no people with exactly the same heart characteristics. As long as there is no serious heart disease, the shape of the heart will hardly change under natural circumstances. But for the same person, will the heart never change?

  Some experts have questioned this, saying that human heart activity will fluctuate with age or physical activity, which will affect the identification of the system. There is no denying that this is a question that everyone will be interested in — — With age and physical activity, will it significantly affect our heart activity? And is our daily heart rate data relatively fixed?

  In this regard, the reporter interviewed Ding Chunhua, director of the Department of Cardiology, Peking University Aerospace Center Hospital. "The position, size and pulsation of each person’s heart change with heart rate, physical activity, age and health, and of course it is relatively stable in the short term." Director Ding said that our heart rate mainly changes with the intensity of daily activities, and the heart can beat from 60 to 70 times per minute in peace to 130 to 150 times per minute during exercise.

  For the heart recognition system, the biggest "soft spot" lies in the recognition error when the heart suddenly breaks down. In addition, the sensitivity of Doppler detection may be affected by people’s fatness, clothes they wear and the shielding of the lungs from the heart. Just like "face brushing technology" meets "twins", the heart recognition system also has the difficulty of improving recognition; Whether this "difficulty" is formed is a test of our health.

  In the future, biometrics will gradually replace bank passwords. In other words, if the heart recognition system can be widely used, what we need is a set of "stable" heart data. Director Ding told reporters that the health of the heart needs to pay more attention to developing good health habits, such as quitting smoking and drinking, eating a low-salt and low-fat diet and exercising moderately.

  [topic extension]

  "Composite Biometric Technology" will replace "Single Biometric Technology"

  Once upon a time, passwords composed of symbols and numbers were the best guards of security barriers, but now this traditional "secret" method seems to be outdated. And those human biological data that we are born with are like keys to unlock the body code, which can accurately locate everyone in the vast sea of people. Seeing the owner’s face, the door opened automatically; Give an instruction orally and the bill will be settled automatically … … In addition to face recognition and voiceprint recognition, there is even a "taste print recognition technology" with special functions, which is often applied to — — As long as you go to the crime scene to filter, concentrate and save the air, and then smell the suspects one by one with an electronic nose or a police dog, after comparison, you can accurately lock the criminals. "The smell of your body will reveal your secret" is no longer a joke.

  Not long ago, Visa, a payment processing giant, launched a new platform, allowing banks to apply various types of biometric technologies, including fingerprints, faces and voices, to credit card applications and payments. Although almost every bank is interested in this technology, many people are worried about it. There is no denying that human biological data is very special, but if it is stolen, it may cause permanent harm. Therefore, for banks, the combination of biometric technology and traditional mode, multi-recognition technology (such as the combination of face brushing and voice brushing), and input of reserved mobile phone number and password may effectively improve the security of operations such as withdrawal.

  All success will not happen overnight. At least in the short term, biometrics will not completely replace the traditional identification technology, but will be the assistance and supplement of traditional methods such as passwords. Experts say that in the future, composite biometric technology will gradually replace single biometric technology, and people can use the most user-friendly, efficient and safe identification methods for different application scenarios.
