Notice on rectifying and standardizing the opinions of the pharmaceutical market

　　

People’s governments of cities, counties and autonomous counties, and relevant units directly under the provincial capital:

　　Now, with the consent of the provincial people’s government, we will forward the Notice of the General Office of the State Council on Forwarding the Opinions of the State Council Economic Restructuring Office and other departments on rectifying and standardizing the drug market (No.17 [2001] of the State Council, hereinafter referred to as the Notice) to you, and now we put forward the following opinions, please implement them together.

　　First, rectifying and standardizing the drug market is an important measure to standardize the drug circulation order and promote the healthy development of the pharmaceutical industry. People’s governments at all levels and relevant departments should strictly follow the spirit of the the State Council Notice and the arrangements of the provincial party committee and government for rectifying the market economic order, intensify the rectification of the pharmaceutical market, and severely crack down on illegal and criminal activities of manufacturing and selling counterfeit and inferior drugs. Governments at all levels should be serious and responsible, resolutely oppose all forms of local protectionism, take practical and effective measures, strengthen supervision of the drug market in their respective jurisdictions, and investigate and deal with all kinds of illegal and illegal drug trading.

　　Two, all levels of health, price, economy and trade, drug supervision, Chinese medicine and other departments should improve the centralized bidding and purchasing system of drugs, and strengthen the supervision of drug bidding and purchasing behavior and price. This year, the main drug varieties of medical institutions at or above the county level in the province should be fully purchased by centralized bidding, and the bidding volume of drugs should reach more than 50% of the usage. On the premise of not exceeding the maximum retail price stipulated by the government, the winning drugs can be priced according to the difference rate stipulated by the bid price; Most of the benefits of reducing drug prices through bidding procurement should benefit patients. All relevant departments should strive to improve the transparency of drug prices. For drugs with market-regulated prices, it is necessary to gradually print retail prices on drug packaging, so as to clearly mark prices. Resolutely crack down on indiscriminate price increases or low-price dumping, maintain normal drug price order, and effectively protect the vital interests of the people.

　　Three, all localities should combine this year to carry out the "anti misleading, false" advertising market governance special action, comprehensively rectify the drug advertising market order. Focus on the control of illegal, illegal, unscientific, exaggerated efficacy, deceiving consumers; Severely punish acts that interfere with people’s rational and safe use of drugs, and standardize the release order of drug advertisements. Those who publish false drug advertisements after investigation shall be punished according to law.

　　Four, rectify and standardize the drug market is an important work related to people’s health and social stability and development. Governments at all levels and relevant departments should, in combination with the actual situation of their own departments in the region, pay close attention to formulating implementation plans to ensure that all measures to rectify and standardize the drug market are implemented.

Opinions on rectifying and standardizing the pharmaceutical market

The State Council Economic Restructuring Office, State Planning Commission and State Economic and Trade Commission

Ministry of Health, State Drug Administration and State Administration for Industry and Commerce

(January 19th, 2001)

　　In order to further implement the spirit of the Notice of the General Office of the State Council on Forwarding the Guiding Opinions of the State Council Economic Restructuring Office and Other Departments on the Reform of Urban Medical and Health System (No.16 [2000] of Guo Ban Fa), deepen the reform of pharmaceutical production and circulation system, promote the transformation of functions of relevant government departments, strengthen supervision, treat both the symptoms and root causes, intensify the rectification of the pharmaceutical market, standardize the order of the pharmaceutical market, and promote the healthy development of the pharmaceutical industry, we hereby put forward the following opinions:

　　First, crack down on illegal and criminal activities of manufacturing and selling counterfeit and inferior drugs.

　　All regions and relevant departments should continue to crack down on the illegal and criminal activities of manufacturing and selling fake and inferior drugs on the basis of conscientiously implementing the notice of the State Council on launching joint action to crack down on illegal and criminal activities of manufacturing and selling fake and inferior commodities (Guo Fa [2000] No.32). For major and important cases of manufacturing and selling fake and inferior drugs that have been discovered, drug supervision, public security, industrial and commercial administration, supervision and other departments should trace back to the source, thoroughly identify manufacturing and selling dens, circulation channels, storage places, sales places and people involved, eliminate the root causes of manufacturing and selling fake and inferior drugs, resolutely punish criminals and disciplinary personnel, and especially punish the chief criminals and recidivists who manufacture and sell fake and inferior drugs and constitute crimes quickly and severely according to law. Drug supervision and other departments should adhere to the combination of centralized rectification and strengthening daily supervision, strengthen market supervision and deepen reform, combine counterfeiting with supporting excellent enterprises, improve the drug quality supervision system and inspection system, and purify the drug market environment.

　　Two, the rectification of all kinds of illegal and illegal drug business behavior.

　　It is necessary to take practical and effective measures to comprehensively strengthen the management of drug market access, rectify all kinds of illegal and illegal drug sales, ban unlicensed drug sales and illegal transactions, and investigate and deal with giving and receiving kickbacks and other commercial bribery in drug purchase and sale activities. In the work of banning drug markets, it is necessary to implement the responsibility system of local governments and resolutely oppose various forms of local protectionism. Relevant parties should unify their thinking, cooperate with each other, consolidate the achievements of rectifying the pharmaceutical market, and properly handle the aftermath. If the banned illegal drug trading market turns dark or resurfaces, it should continue to be severely cracked down and severely punished. If the problem is serious, the relevant localities, departments and their responsible persons should be held accountable.

　　Three, strictly implement the drug management system of separating government from enterprise.

　　Drug supervision and other relevant departments shall, in accordance with the requirements of the Notice of the State Council on Approving the Reform Plan of Drug Supervision and Management System in National Medical Products Administration (Guo Fa [2000] No.10), follow the principle of separating government from enterprises, separating supervision and law enforcement from industry management functions, highlighting supervision and management, being unified and efficient, and being consistent in responsibilities and rights, speed up the reform of drug supervision and management system and improve the drug supervision and management system. Drug supervision and other departments should be completely decoupled from their affiliated pharmaceutical companies or pharmaceutical institutions affiliated in various forms and names, and should not maintain economic interests with any pharmaceutical institutions. In the development of pharmaceutical industry and enterprises, we should support and play the role of industry self-regulatory organizations.

　　Four, promote the development and alliance of superior pharmaceutical enterprises.

　　Resolutely break departmental or local monopolies, ownership restrictions and administrative protection that hinder fair competition, adjust policies and regulations that are not conducive to giving full play to the positive role of market mechanisms, establish a drug quality management monitoring system organized by relevant state departments, cancel repeated testing, repeated examination and approval, and repeated issuance of "quasi-sales licenses" for pharmaceutical enterprises in various places, and cancel restrictions on pharmaceutical enterprises in other regions from entering the local drug market in the name of filing and registration. We should give full play to the role of market mechanism and optimize the structure of pharmaceutical industry. It is necessary to create an environment of fair competition, support superior pharmaceutical enterprises to expand their business scale through acquisitions and mergers, promote the development of marketing methods such as drug agency distribution and chain operation, and form a number of cross-regional, large-scale, intensive and high-level pharmaceutical enterprise groups to play a key role in drug production and circulation.

　　Five, reverse the situation of low-level duplication of drug production.

　　Local people’s governments at all levels should make up their minds to rectify small pharmaceutical factories and shut down a number of small pharmaceutical factories that pollute the environment, waste resources, do not conform to industrial policies and industry development plans, have low-level redundant construction, fail to meet GMP standards for pharmaceutical production enterprises or fail to operate normally. Drug regulatory authorities should clean up and rectify the hospital preparation room, and hospitals that can normally supply preparations in the market shall not repeat production, and hospitals that do not have preparation conditions shall not be renewed.

　　Six, clean up and rectify the drug circulation enterprises

　　Cleaning up and rectifying drug circulation enterprises should be combined with the work of drug business renewal. Drug circulation enterprises that have an imperfect quality assurance system, irregular business practices and fail to meet the conditions for renewal shall not be renewed; Drug circulation enterprises that are insolvent, on the verge of bankruptcy, or fail to meet the quality management standards (GSP) for drug business within a certain period of time will be resolutely disqualified; Drug circulation enterprises that cannot operate drugs normally and mainly rely on renting office buildings, warehouses and other properties to survive should be rectified, and those that engage in illegal investment operations should be investigated and punished according to law until their drug business licenses are revoked.

　　Seven, improve the centralized bidding system of drugs.

　　The health department should standardize the management of drug use in medical institutions, expand the varieties of drugs purchased by centralized bidding, and gradually bring the main drug varieties into the scope of centralized bidding and purchasing. Strict examination and management should be carried out on important links in drug procurement by tender, such as bid evaluation methods and the composition of expert database for the whole society, so as to ensure the openness, fairness and impartiality of drug procurement by tender. Health, drug supervision, price authorities and other departments should supervise the bidding and purchasing behavior and price of drugs. The retail price of drugs purchased by bidding should be reasonably set based on the actual purchase price. The benefits of reducing drug prices through bidding should mainly benefit patients, and medical institutions can share a certain proportion.

　　Eight, promote the electronic trading of medical commodities.

　　Establish and improve the electronic trading system of medical commodities certified, supervised and managed by relevant government departments, actively promote the electronic trading of medical commodities, give full play to the role of electronic trading system as a bridge between drug production, circulation and consumption, communicate information in time, realize fast trading, and use this system to entrust centralized bidding and purchasing of medical commodities, bring trading behavior into a standardized and open track, and correct unhealthy trends in the purchase and sale of medical commodities from the system.

　　Nine, strengthen the construction of rural drug supply network

　　It is necessary to effectively solve the problem of lack of regular and stable drug supply channels in the vast rural areas and strengthen the construction of rural drug supply networks. Encourage large and medium-sized pharmaceutical wholesale enterprises to merge with small pharmaceutical wholesale enterprises, extend the sales network to the county level, and develop rural drug sales outlets to facilitate farmers to purchase drugs. Promote centralized bidding and purchasing drugs through rural health service network. In remote areas, rural health service management can also be integrated, and township hospitals can purchase drugs for rural doctors in a unified way to prevent counterfeit and inferior drugs from flowing to rural areas and ensure the safety of farmers’ medication.

　　Ten, the implementation of separate accounting and management of medicine.

　　Health departments and medical institutions at all levels should actively implement the policies and measures of separate accounting and management of medicines, and strictly implement the relevant provisions on the management of two lines of revenue and expenditure. On the basis of standardizing financial subsidies and adjusting the price of medical services, the outpatient pharmacy of medical institutions will be gradually changed into a pharmaceutical retail enterprise, with independent accounting and tax payment according to regulations, and equal competition with social retail pharmacies will promote the socialization, specialization and intensification of drug circulation, improve efficiency and reduce costs.

　　Community health organizations, outpatient departments and individual clinics can only distribute commonly used and first-aid drugs approved by provincial health and drug supervision departments. Health and drug supervision departments should pay close attention to formulating the catalogue of commonly used and first-aid drugs and related management measures, and implement the above measures as soon as possible at the grassroots level.

　　Eleven, accelerate the implementation of the classified management system of prescription drugs and over-the-counter drugs.

　　Drug supervision and other departments should actively cooperate, improve policies, standardize and manage the sales of prescription drugs as soon as possible. On the basis of ensuring safety and effectiveness, in order to meet the needs of people’s self-care, speed up the selection of over-the-counter drugs and expand the circulation channels of over-the-counter drugs. Class B OTC drugs can be sold in retail stores of daily necessities upon approval.

　　Twelve, improve the management of new drug research and approval.

　　It is necessary to revise the standards of new drugs and encourage the research and innovation of new drugs. If the technical content is not high and the research and production are repeated at a low level, the drug regulatory authorities should strictly check and not approve the production. Those who resort to deceit in the approval of new drugs should be dealt with severely according to law. The policies and regulations, working procedures and time limits of new drug approval management should be open to the public and subject to social supervision.

　　Thirteen, increase the intensity of drug price supervision.

　　Gradually implement the system of drug price publicity and the system of printing retail prices on drug packaging, and increase the supervision of drug prices. This work starts with some drugs with market-regulated prices and is gradually extended to all kinds of drugs sold in China. It is necessary to make it clear that the price stipulated by the state is the highest price limit, and to retail drugs in hospitals or pharmacies, it is allowed to sell or print the price below but not above the public price.

　　Fourteen, strengthen the supervision and management of drug advertising.

　　Drug regulatory authorities at all levels and administrative departments for industry and commerce should conscientiously implement the spirit of the Notice of the State Drug Administration and the State Administration for Industry and Commerce on Strengthening the Examination and Management of Prescription Drug Advertisements (No.14 [2001] of the State Administration of Medicine) and gradually stop advertising prescription drugs in the mass media. Drug regulatory authorities should strictly examine all kinds of drug advertisements in accordance with the relevant provisions, and supervise and inspect their daily publication and broadcasting. If illegal or illegal drug advertisements are found, they should take timely measures to deal with them accordingly. The administrative department for industry and commerce should intensify the investigation and punishment of illegal and illegal drug advertisements, and effectively regulate the release order of drug advertisements.

　　Fifteen, comprehensively implement the measures to rectify and standardize the drug market.

　　Rectifying and standardizing the pharmaceutical market is related to the vital interests of the broad masses of the people, to the healthy development of the pharmaceutical industry and health undertakings, and to the overall situation of reform, opening up and stability. All regions and relevant departments should attach great importance to it, strengthen leadership, unify their thinking, raise awareness, overcome local and departmental departmentalism, and comprehensively use legal, economic, administrative and public opinion means in a spirit of being highly responsible to the country and the people to conscientiously rectify and standardize the drug market.

　　All provinces, autonomous regions and municipalities directly under the Central Government shall, in accordance with the above opinions and in combination with the actual situation in the region, pay close attention to formulating implementation plans, make careful arrangements and organize them carefully to ensure that all measures to rectify and standardize the drug market are implemented. The relevant departments of the State Council will timely supervise and inspect the implementation of this opinion in various regions.

　　In a blink of an eye, 2018 is about halfway through. In July, there is a big wave of new policies about your wallet: the reduction of tariffs on imported consumer goods, the cancellation of traffic roaming fees, etc. What other new policies are there?

　　1 enterprise employees’ pensions shall be subject to the central adjustment system.

　　The State Council recently issued the Notice on Establishing the Central Adjustment System of the Basic Endowment Insurance Fund for Enterprise Employees, and decided to establish the central adjustment system of the endowment insurance fund, which will be implemented on July 1, 2018. On the basis of the current provincial overall planning of basic old-age insurance for enterprise employees, a central adjustment fund for old-age insurance will be established, and the old-age insurance funds in various provinces will be appropriately adjusted to ensure that basic pensions are paid in full and on time.

　　The relevant person in charge of the Ministry of Human Resources and Social Security said that the implementation of the central fund transfer system will not increase the burden on enterprises and individuals and will not affect the treatment of retirees. First, do not increase the proportion of contributions paid by enterprises and individual employees. The establishment of a central fund adjustment system is mainly to adjust the surplus and deficiency of funds between provinces. The total income and expenditure of the national endowment insurance fund in the current period has not changed, and enterprises and individual employees do not need to pay extra fees, which will not increase the overall burden of society. Second, it will not change the current pension insurance benefits calculation and adjustment methods, and will not affect the personal benefits of retirees. In some provinces, the amount of funds borrowed is greater than the amount of funds allocated. In these provinces, the burden of old-age care is relatively light and the fund support ability is strong. After adjustment, it will not affect the timely and full payment of current pensions. In some provinces, the amount of funds allocated is greater than that of the above solution. Through adjustment, the pressure of fund payment can be appropriately alleviated, and the basic pension can be better guaranteed to be paid in full and on time.

　　2. Adjustment of social security payment base

　　Many places in the country have successively announced the social security payment base in 2018. Taking Beijing as an example, the lower limit of the payment base for employees participating in basic old-age insurance and unemployment insurance is 40% of the average monthly salary of employees in Beijing in 2017, with a minimum of 3,387 yuan, which is 305 yuan higher than last year; For employees who participate in basic medical insurance, industrial injury insurance and maternity insurance, the minimum payment base is 60% of the average monthly salary of employees in this city in 2017, with a minimum of 5,080 yuan, up 456 yuan from last year.

　　Social security payment is related to the treatment of the insured after retirement. Only when a certain payment level is reached can a better treatment level be achieved. If the payment level is too low, the pension level is still low. In other words, the payment level will increase with the increase of average salary, and the future treatment level will also increase.

　　3. The tax incentives for scientific and technical personnel will be "received"

　　The Ministry of Finance, the State Taxation Administration of The People’s Republic of China and the Ministry of Science and Technology jointly issued the Notice on Individual Income Tax Policies for Scientific and Technological Personnel to Earn Cash Rewards from Their Post Scientific and Technological Achievements, which made it clear that since July 1, 2018, non-profit research and development institutions and institutions of higher learning approved according to the law on promoting the transformation of scientific and technological achievements, the cash rewards given to scientific and technological personnel from their post scientific and technological achievements can be included in the "salary and salary income" of scientific and technological personnel in the current month at a reduced rate of 50%, and personal income tax can be paid according to law.

　　It is cheaper to import daily consumer goods.

　　With the approval of the State Council, the MFN tariff rate of some consumer goods will be reduced from July 1, 2018, involving 1449 tax items, and the average tax rate will be reduced from 15.7% to 6.9%, with an average decrease of 55.9%. Reduce the average import tariff rate of clothing, shoes and hats, kitchens and sports and fitness products from 15.9% to 7.1%; Reduce the average import tariff rate of household appliances such as washing machines and refrigerators from 20.5% to 8%; Reduce the average import tariff rate of processed foods such as aquaculture, fishing aquatic products and mineral water from 15.2% to 6.9%; The average import tariff rate of washing products, cosmetics such as skin care and hairdressing and some medical and health products will be reduced from 8.4% to 2.9%.

　　5. Tariff reduction of imported cars and parts.

　　With the approval of the State Council, from July 1, 2018, the tariffs on automobiles with tax rates of 25% and 20% will be reduced to 15%, with tax reductions of 40% and 25% respectively; The tariffs on auto parts with tax rates of 8%, 10%, 15%, 20% and 25% will be reduced to 6%, with an average tax reduction of 46%.

　　6. The vehicle purchase tax will be levied on the trailer by half.

　　The Ministry of Finance, State Taxation Administration of The People’s Republic of China, and the Ministry of Industry and Information Technology jointly issued the Announcement on Reducing Vehicle Purchase Tax on Trailers. From July 1, 2018 to June 30, 2021, the vehicle purchase tax will be reduced by half. The date of purchase shall be determined according to the issuance date of the Uniform Invoice for Motor Vehicle Sales, Special Payment Letter for Customs Tariff or other valid documents.

　　7. Preferential tax policies for venture capital enterprises and angel investment individuals.

　　The Notice on Tax Policies for Venture Capital Enterprises and Angel Investors jointly issued by the Ministry of Finance and State Taxation Administration of The People’s Republic of China promoted the preferential tax policies for venture capital enterprises and angel investors, that is, the preferential policies for venture capital enterprises and angel investors to invest in seed-stage and start-up technology-based enterprises, and the taxable income was deducted by 70% of the investment amount, which was implemented nationwide by eight pilot areas of comprehensive innovation reform and Suzhou Industrial Park.

　　This Notice clarifies that the personal income tax policy for angel investment will be implemented as of July 1, 2018, and other policies will be implemented as of January 1, 2018; The above-mentioned tax policy can be applied to the investment that occurred within 2 years before the implementation date and has been invested for 2 years after the implementation date and meets the prescribed conditions.

　　8. Traffic "roaming" fee is cancelled

　　On June 22nd, China Mobile, China Unicom and China Telecom successively announced that, starting from July 1st, 2018, the roaming fee will be cancelled, and the provincial traffic of new and old mobile phone users will be upgraded to domestic traffic (excluding Hong Kong, Macao and Taiwan traffic).

　　Previously, the Ministry of Industry and Information Technology launched a series of measures to reduce the growth rate of mobile traffic, including: from July 1, the "roaming" fee for mobile traffic will be cancelled, and basic telecommunications companies will be encouraged to launch large-flow packages. The average unit price of mobile traffic will be reduced by more than 30% during the year. Further reduce household broadband charges and international, Hong Kong, Macao and Taiwan roaming charges. Promote enterprises to optimize and streamline tariff packages, and study and introduce relevant policies and measures to standardize tariff management. Support all localities to expand the coverage of wireless networks in public places and provide users with free Internet access services.

　　9. Some high-speed rail tickets are discounted by 6.5%

　　Starting from July 5 this year, the announced fares of high-speed trains running on the six sections of Hefei-Wuhan, Wuhan-Yichang, Guiyang-Guangzhou, Liuzhou-Nanning, Shanghai-Nanjing and Nanjing-Hangzhou were optimized and adjusted. This time, it is clear that the published fare is the highest price limit. Railway-related enterprises can lower the fare within the price limit by season, time, seats and sections according to the passenger flow, with a maximum discount of 6.5%. Compared with the current situation, the adjusted executive fare has generally increased and decreased.

　　10. Tianjin will raise the unemployment insurance standard from July 1st.

　　A few days ago, Tianjin issued a notice, starting from July 1 this year, it will raise the unemployment insurance payment standard.

　　According to the "Notice on Improving the Payment Standard of Unemployment Insurance in Tianjin", if the payment period is from the first month to the twelfth month, the monthly payment standard will be raised from 1150 yuan to 1240 yuan; For the 13th to 24th months, the monthly payment standard was raised from 1,110 yuan to 1,200 yuan, respectively increasing the 90 yuan.

　　The standard of one-time living allowance for farmers’ contract workers was raised from the current monthly payment standard of 690 yuan to 744 yuan, with an increase of 7.83% in 54 yuan. (Gao Chang/Compilation)

　　At the Los Angeles Convention and Exhibition Center, gamers are experiencing virtual reality (VR) devices. Bright pictures/vision china

　　With the establishment of virtual reality technology (VR) laboratory in Alibaba, Stormwind TV released the first VR TV, Huawei announced its first generation of VR glasses products, and the VR industry also rose. It can be predicted that in the near future, the wide application of mobile Internet, big data and other information technologies will promote the further development of VR technology. So how is the so-called virtual reality technology realized?

　　1. Frontier disciplines of integrated application of software and hardware.

　　Virtual reality technology (VR) is a computer simulation system technology to create and experience a virtual world. That is to say, VR uses computers to generate a simulation environment, and uses multi-source information fusion for interactive three-dimensional dynamic visual scene and system simulation of entity behavior to immerse users in this environment. Up to now, there is no universal definition of it in the world, but it can generally be considered that it creates another unreal world that is as real, interactive and immersive as possible for human beings outside the real space by using various human-computer interaction technologies, so that human beings can roam in it, experience the most real virtual space and walk in their dreams without any restrictions.

　　VR has been widely used in new media, aerospace, military, engineering and other cutting-edge scientific and technological fields, and will be more widely used in our daily life as an advanced technical means. Because most of the monitors used by virtual reality in human-computer interaction are helmet-mounted enhanced portable display systems, it is one of the most promising application fields of portable display systems. Users only need to wear virtual reality equipment, such as helmets, glasses, etc., and they can feel all kinds of scenes set in the device.

　　VR system generally includes user control systems, such as human motion monitoring, control devices such as joystick, keyboard and mouse, and simulation feedback systems and processing systems for human senses such as vision, hearing, touch, smell and taste, as well as information display systems perceived by human beings, such as monitors, stereos and three-dimensional seats. Among them, visual and auditory control and simulation are the main development direction of VR at present, and helmet-mounted enhanced portable display system is the main product form used by users.

　　2. Construct a virtual space in advance in the computer.

　　VR is an interdisciplinary subject that relies on a large number of computer software technologies such as artificial intelligence, pattern recognition, graphics, bottom interface and new display technology, field sensor technology, force feedback system, wireless and wired communication technology. In essence, VR is the representation of the real world and the realization of dreams; From a technical point of view, it is a comprehensive application of cutting-edge technologies in the fields of software and hardware and an object-oriented comprehensive technology development.

　　VR enables people to experience a fantastic virtual reality while wearing a helmet-mounted enhanced portable viewing system. In fact, these virtual reality scenes use complex software technology to construct a real virtual space in the computer in advance. Every point in the space has many dimensions of information such as coordinates, colors, normals, logical relationships and so on in X, Y and Z. The computer then determines the position of people in the virtual scene through user input devices such as sensors, joysticks and mice, and finally reproduces the picture to the user’s eyes through the computer, thus creating a virtual space.

　　If such a series of tasks can be connected, and the operation time of the whole system is less than the visual retention time of people, users will have the feeling of roaming in the virtual reality world on the virtual image display screen of the head-mounted enhanced portable display system. VR is to create a virtual environment that makes you feel that this is reality. Entertain and attract you through this fictional reality.

　　3.MR— — Break through the boundary between virtual and reality

　　In addition to VR technology, there is also augmented reality technology, namely AR. Now there are only more than 20 authoritative companies in the world conducting research. Google’s technology is relatively mature, and its goal is to put the virtual world in the real world and interact with it on the screen. This technology was first put forward in 1990. With the improvement of the computing power of portable electronic products, it is expected that its application will be more and more extensive.

　　In essence, AR is the interaction between digital media and the real world. The imaging concept of AR and the immersive imaging experience of VR have created a hybrid virtual reality technology, namely MR, which is based on holographic projection reality. At the Microsoft Developer Summit held in June this year, satyanarayana nadella, CEO of Microsoft, emphasized the importance of its hybrid virtual reality technology equipment — — The correct "opening" way of Hololens is neither a VR helmet nor AR glasses. This hybrid virtual reality device holographically projects computer-generated 3D virtual objects into real space, and the wearer of Hololens can interact with 3D virtual animation in real space and trigger corresponding functions. The imaging principle of this kind of MR equipment is different from that of immersive VR equipment. It projects virtual images into real space, but the imaging effect of the projected holographic 3D images breaks through the boundary between virtual and real world.

　　Research and Application of Virtual Reality Technology

　　The focus of NASA’s research on this technology is the real-time simulation of space station manipulation, and they use a lot of cockpit-oriented flight simulation technology. Such as the simulation of the Hubble Space Telescope and the experimental plan of "Virtual Planet Exploration", this project enables the "Virtual Explorer" to use the virtual environment to explore distant planets, and the first goal is Mars.

　　The University of North Carolina is the earliest and most famous university to study virtual reality technology. Their main research includes molecular modeling, aviation driving, surgical simulation, architectural simulation and so on. On the display technology, the university has developed a parallel processing system called Pixel Plane, which helps users to build real-time dynamic display in complex scenes.

　　MIT was originally a pioneer in studying artificial intelligence, robotics, computer graphics and animation. These technologies are the basis of virtual reality technology. In 1985, a media laboratory was established to conduct formal research on virtual environment.

　　The laboratory of man-machine interface technology in Washington Technology Center of the University of Washington plays a leading role in the research of new concepts, and is also conducting research on sensory, perceptual, cognitive and motor control abilities. They introduced the research of virtual reality technology into the fields of education, design, entertainment and manufacturing. For example, Boeing’s V22 transport plane was built in the laboratory before it was put into production.

　　Illinois State University has developed a distributed virtual reality technology system that supports remote collaboration in vehicle design. Engineers from different countries and regions can design in real time through computer networks. In the process of designing a vehicle, various components can share a virtual environment, and can view the video transmission and corresponding positioning direction of any position of the other party. Virtual prototype is adopted in the system, which reduces the time for designing images and new products to enter the market, so that products can be estimated and tested before production, and the quality of products is greatly improved.

　　George Mei Sen University has developed a real-time fluid simulation system in a dynamic virtual environment. In a distributed interactive simulation system, the physical characteristics of complex fluids in the real world are simulated, including simulating ships running across the water, stirring liquids, mixing liquids of different colors, and the influence of rain on the terrain.
