Professor Chen has published 100 books, including 10 university textbooks, and 600 poems.Author: Chen Zhengui wang Xuan (May 5, 1937.5-February 13, 2006), male, born in Shanghai, Jiangsu Province, academician of Chinese Academy of Sciences, Academician of Chinese Academy of Engineering, academician of Third World Academy of Sciences, professor of Peking University.He is a computer character information processing expert, the founder of computer Chinese character laser typesetting technology, the forerunner of contemporary Chinese printing revolution, known as “the father of Chinese character laser typesetting system”, known as “the second invention of Chinese character printing”, “contemporary Bi Sheng”, “a scientist with market vision”.Wang Xuan was born in an intellectual family in Shanghai. His father, Wang Shouqi, graduated from Shanghai Nanyang University (now Shanghai Jiao Tong University).Mother Zhou Miao qing was born in a scholarly family.Wang Xuan received good education because of his parents’ cultural accomplishment and solid family environment.In the autumn of 1954, Wang Xuan was admitted to the Department of Mathematical Mechanics of Peking University.In 1958, Wang Xuan graduated from The University and worked as a teaching assistant in the Radio Department. He presided over the computer logic design of the electronic tube and the debugging of the whole machine, and also participated in part of the circuit design. He has been struggling in the front line of hardware.In 1964, Wang Undertook the ALGOL 60 compilation system for DJS 21 computer, which was then undergoing hardware design, and explored the architecture of computers suitable for high-level languages.Because Wang Xuan has hardware practical experience, so it is easy to come up with hardware methods to overcome the bottleneck in the program operation.After several years of efforts, the system was successfully developed and promoted in dozens of users. It became the earliest high-level language compilation system in China and was listed in the annals of the history of computer industry.This knowledge and practice in both software and hardware became the decisive factor for Wang or Xu to undertake the development of laser phototypesetting system.In the early 1960s, Wang xuan developed the habit of understanding the current situation of foreign countries before doing a project.In order to speed up the speed of English reading, he began to practice English listening in 1963, more than two years of listening half an hour a day made his reaction speed significantly accelerated.In 1975, Wang Xuan heard that the country had a “748 project”, namely the Chinese character information processing system project, in which the value and difficulty of the project “Precision phototypesetting system” attracted Wang Xuan.At that time, there were 5 powerful units in China engaged in the development of Chinese character phototypesetting system, but the choice is analog storage.In the summer of 1976, After a lot of investigation and research, Wang Decided to adopt digital storage mode, skipping the optical mechanical type of the second generation of phototypesetters popular in Japan, the cathode ray tube type of the third generation of phototypesetters popular in Europe and the United States, and directly developed the fourth generation of laser phototypesetter system without commodities abroad.He skillfully use mathematics knowledge and practice experience of software and hardware for words, printed in Chinese characters font of Chinese characters, the technical difficulties brought by the precision typesetting require high resolution, invented the high-resolution glyph high-magnification information compression (compression ratio of 500:1) and high speed recovery method, first to design the special chip for increasing the glyph recovery rate,It is the first time in the world to use control information (or parameters) to describe stroke width, corner shape and other characteristics, so as to ensure the stroke symmetry and width consistency after the font becomes smaller.In the west in the mid – 80 – s began to adopt the description of the “outline and parameters” way (i.e., called the HINT information technology information or control), and Wang Xuanzao 8 years, puts forward and realizes the method, to become the first person to use this method in the world, this invention to become the foundation of uh guano and founder of laser typesetting system, won the European patent and 8 patents of China.Wang Xuan became the first person in China to get a European patent.In September 1976, after learning wang xuan’s plan, the Ministry of Electronic Industry gave strong support and formally assigned the development task of the Chinese character precision phototypeset system in the “748 Project” to Peking University, and established the Chinese Character Information Processing Technology Laboratory of Peking University. Wang Xuan was responsible for the overall design and development of the whole system.On July 27, 1979, with the joint efforts of the cooperative units, Wang Xuan presided over the development of the Chinese character precision system of the main project, from the laser imagesetter output an Octavia newspaper negative.Vice Premier Fang Yi of The State Council spoke highly of pKU after his visit.On August 11, 1979, Guangming Daily reported with a banner headline “A major breakthrough in the research and application of Chinese Character Information Processing Technology — The main project of laser Chinese Character editing and typesetting System designed by Our country has been successfully developed”, which caused a great response at home and abroad.On February 22, 1980, Jiang Zemin, then deputy director of the Import and Export Administrative Commission of The State Council, wrote a four-page letter to several vice-premiers of The State Council, opposing the introduction of foreign products unsuitable for national conditions and firmly supporting the research and development work of Peking University and other institutions.On September 15, 1980, the research group led by Wang Xuan successfully produced a sample book of The Sword of Wu Hao with laser phototypesetting system, which was the first book published in China in the process of bidding farewell to type.Comrade Fang Yi saw the comments: “This is a gratifying achievement, printing from the age of fire and lead to the age of computers and lasers, we suggest support.”On October 25, 1980, Comrade Deng Xiaoping issued an instruction that should be supported.That year, Wang xuan was promoted to associate professor.In July 1981, wang xuan developed China’s first computer laser typesetting system of Chinese characters of the original rational prototype (type I) of hua by state general administration of the computer industry and the Ministry of Education held a joint ministerial appraisal, appraisal conclusion is “compared with the foreign phototypesetter, leading in Chinese character information compression technology, laser output precision and some features of software has reached the international advanced level”.In 1983, the Computer Science and Technology Research Institute of Peking University was established on the basis of the former Chinese Character Information Processing Technology Research Institute, and Wang was elected as the deputy director.In early 1985, huaguang II was successfully developed and put into trial operation in Xinhua News Agency.In May 1985, wang passed the national appraisal and was selected as Beijing Model Worker and advanced Individual with great contribution.He was promoted to professor in 1984.After that, Huaguang type ⅲ machine, type ⅳ machine and Founder 91 machine were introduced successively.In 1987, Economic Daily became the first newspaper in China to test huaguang TYPE III machine. The following year, the printing house of Economic Daily sold all its type and became the first printing house in the world to completely abolish Chinese type.In 1989, Huaguang iv machine began to be popularized in the domestic press, publishing and printing industry. By the end of the year, all the foreign companies that came to China to develop and sell phototypesetting system withdrew from the Mainland Market.By 1993, 99% of the domestic newspapers and more than 95% of the book and print factories adopted the domestic system, and the Chinese newspaper and print industry set off a technological revolution of “saying goodbye to lead and fire, and ushering in light and electricity”.From 1991 to 1994, Wang Xuan led the scientific research collective of Peking University to seize opportunities and lead the market with innovative technologies, which led to three technological innovations in the newspaper and printing industry.Bid farewell to the newspaper fax machine, and directly promoted the new technology of remote edition transmission based on page description language (since 1991), which greatly improved the quality and circulation of Chinese newspapers;Bid farewell to the traditional stage of electronic color separators, and directly develop open color desktop publishing system (since 1992), leading to a color publishing technology innovation: bid farewell to paper and pen, and adopt the computer integration solution of editing process management (since 1994).In 1991, Wang was elected director of the Computer Research Institute of Peking University.In 1991 and 1994, the State Key Laboratory of Character Information Processing and the National Engineering Research Center of New Electronic Publishing Technology were respectively established based on the Institute of Computer.From 1992 to 1994, Wang xuan was successively elected academician of the Three Institutes, and was elected member of the Eighth CPPCC in 1992.Wang xuan was elected vice-chairman of the central jiusan society in 1995, was elected vice chairman of China Association for Science and Technology, 1996, 1998, was elected nine National People’s Congress standing committee, deputy director of the general committee of National People’s Congress, and friendly group, chairman of the National People’s Congress of China, the Philippines and the Ministry of Foreign Affairs china-russia friendship, peace and development committee, was elected vice President of China international exchange association, 1999,He was elected vice president of China Invention Association in 2000.For his outstanding contribution, Wang xuan won the gold medal in the 14th Geneva International Invention Exhibition in 1986.In 1987 and 1995, he won the first prize of National Science and Technology Progress Award and the first Bi Sheng Award.Chen Jiageng Prize in 1990;In 1991, it won the special prize of national major technology and equipment development.Wang Xuan successfully developed the world’s first Chinese color phototypeset system. In 1992, he won the Gold Medal of China patent Invention, the Science Prize of UNESCO, and the Special prize of National Major Technology and Equipment development.In 1996, he won the Top Ten Scientific and technological achievement award of China.In 1993, 1995, 1999 and 2000, he was awarded the title of National Model worker, National Advanced Worker and Model of the Capital, and the glorious title of Capital Spiritual Civilization construction. He was also awarded the title of Beijing Model worker for many times.In the 2001 national Science and technology Award selection, Wang Xuan won the State Highest science and technology award, winning the highest honor in China’s science and technology field.President Jiang Zemin presented wang with the award certificate in person.In 2009, he was awarded the title of “60 People who influenced Chinese Economy in 60 Years of the Republic” and the title of “Outstanding Publisher in 60 Years of the People’s Republic of China”.Academician Wang Xuan passed away at 11:03 on February 13, 2006 in Beijing at the age of 70.Wang xuan contributions from members of the 1980 s, has been working on the commercialization of scientific research achievements, in the early 1990 s, wang xuan led the team in accordance with the need of the market constantly blaze new trails, has successfully developed on the basis of the page description language of the remote version of the new technology, open color desktop publishing system, computer management system of newsroom process,It has led to three technological innovations in the newspaper and printing industries, making laser phototypesetting of Chinese characters occupy 99% of the domestic newspaper market and 80% of the overseas Chinese newspaper market.A, invention high-magnification information compression technology and high speed recovery method in the summer of 1976, wang xuan invented the high-resolution glyph high-magnification information compression (compression ratio of 500:1) and high speed recovery method, first to design the special chip for increasing the glyph recovery rate, makes the Chinese character glyph recovery rate has reached the leading level in the 700 characters per second,It is the first time in the world to use control information (or parameters) to describe stroke width, corner shape and other characteristics, so as to ensure stroke symmetry and consistency of width after the font becomes smaller.In 1979, Wang Xuan presided over the development of the Chinese character laser phototypesetting system, and output an Octavia newspaper negative from the laser phototypesetting machine.In July 1981, wang xuan developed China’s first computer laser typesetting system of Chinese characters of the original rational prototype (uh guano Ⅰ type) by state general administration of the computer industry and the Ministry of Education held a joint ministerial appraisal, appraisal conclusion is “compared with the foreign phototypesetter, leading in Chinese character information compression technology, laser output precision and some features of software has reached the international advanced level”.From 1991 to 1994, Wang Xuan led the scientific research collective of Peking University to lead the market with innovative technology, which led to three technological innovations of the newspaper and printing industry.Bid farewell to the newspaper fax machine, and directly promoted the new technology of remote edition transmission based on page description language (since 1991), which greatly improved the quality and circulation of Chinese newspapers;Bid farewell to the traditional stage of electronic color separators, and directly develop open color desktop publishing system (since 1992), resulting in a color publishing technology innovation;Say goodbye to paper and pen, adopt computer integration solution of collecting and editing process management (since 1994).In 1992, wang Xuan’s Chinese character font generator was awarded two national patents for a measure to deal with stroke interlacing and a method for piecewise generation of newspaper and book layout dot matrix.He led the Computer Research Institute of Peking University to successfully develop founder color publishing system and put it into use in Macao Daily, which was the first Chinese color newspaper in the world to realize the integrated processing and output of color pictures and Chinese.Led to the innovation of color technology in Chinese newspaper and publishing industry.Led the computer research institute of Peking University, developed by satellite remote transmission of newspapers in the form of page description language of the new technology, was first employed by the People’s Daily, China press skip paper fax machines, direct promotion page description language based remote version of the new technology, to realize the newspaper issued by the national synchronous, with the quality of printing.· Launched the first Chinese professional software based on MS Windows in China.In 1993, Wang Xuan guided his students to develop the world’s first PostScript Level 2 Chinese page interpreter, which was combined with the special coprocessor chip and launched the sixth generation of Founder 93 system, which won the bidding of Ming Pao in Hong Kong.Since then, it has rapidly entered Hong Kong, Macao, Taiwan, Southeast Asia, North America and other places, so far accounting for 80% of the overseas Chinese newspaper market.In 1994, Wang Xuan successfully developed a computer management system for news gathering and editing process, which was first adopted by Shenzhen Evening News, which triggered the technological innovation of “farewell to paper and pen” in the domestic newspaper industry.Seven, in the world’s first use of “parameter description method” Wang Xuan directly developed the west has no products of the fourth generation of laser phototypesetting system.In view of the characteristics and difficulties of Chinese characters, Wang xuan invented the high magnification information compression technology and high-speed restoration method of high resolution glyphs, took the lead in designing corresponding special chip, and used “parameter description method” to describe stroke characteristics for the first time in the world, and obtained the invention patent in Europe and China.These achievements ushered in a new era of Chinese character printing and revolutionized the centuries-old type printing technology in China.On February 4, 2022 in Shenzhen
