70 years since the founding of New China Electronic information technology is developing rapidly In every corner of the world As long as you use electronic devices Get Chinese information You should think of one person He brought the printing press after movable type The "Second Revolution" in China's Printing Industry Because he The inheritance and development of Chinese characters and Chinese culture Entering the information age February 13, 2006 On the day he died People from all over the country Rushed to Peking University to pay his respects to him Express respect for him This person is Wang Xuan Who is Wang Xuan? Why can it cause So many eyes of attention? This matter started from his How to get admitted to the Department of Mathematics at Peking University Screenshot of the video "Contemporary Bi Sheng - Wang Xuan". 【The country’s needs are my choice】 Screenshot of the video "Contemporary Bi Sheng - Wang Xuan". then Mathematics major at Peking University Like a jewel in the crown But computational mathematics was unpopular at that time. Because choosing it It means working with computers. In that era Few people have ever seen a computer. Not to mention studying it. Wang Xuan is guiding young scientific and technological workers to develop new technologies. But Wang Xuan resolutely chose computational mathematics He said “Developing computing technology Not only an international trend It is also a national need If a person puts his work and the future of the country Connected It is likely to create greater value.” Screenshot of the video "Contemporary Bi Sheng - Wang Xuan". 1958 Wang Xuan graduated with honors Stay at school as a teaching assistant And devoted himself to the independently designed Research and development of the "Red Flag" aircraft Due to the huge workload Prolonged physical exhaustion His body collapsed Summer 1961 Wang Xuan had to return to his hometown in Shanghai to recuperate. Is it yourself Full of knowledge and ideas In the future, I can only Have you been soaking up the sun here? He is unwilling Screenshot of the video "Contemporary Bi Sheng - Wang Xuan". At this time The development of world science and technology Constantly changing In the era of global information explosion Electronic typesetting is adopted abroad Already under development Laser phototypesetting system fourth generation machine But China Still using more than a thousand years ago Movable Type Printing According to incomplete statistics The Chinese characters used in casting at that time Lead alloys reached 200,000 tons Copper molds reach 2 million Serious environmental pollution Unbalanced industrial structure The Chinese people have been unable to raise their heads Screenshot of the video "Contemporary Bi Sheng - Wang Xuan". Wang Xuan suddenly realized If all this Can be operated by computer The results will be very different Wang Xuan based his bold idea Directly propose Develop products that the West does not have yet The fourth generation of laser typesetting technology Screenshot of the video "Contemporary Bi Sheng - Wang Xuan". [No blood, no counterattack] Chinese character laser typesetting system That is, every Chinese character Encode into a specific code Save to computer Output Scan directly into words using laser technology But at that time, China was still Lead Printing Era my country plans to develop its own Second generation and third generation aircraft Because the technology is too advanced Wang Xuan has long been under suspicion Some even say he “Playing tricky math games” “You want to develop the fourth generation I also want to develop the eighth generation." Wang Xuan said “It was at that time Learn to grow up amidst the scolding Screenshot of the video "Contemporary Bi Sheng - Wang Xuan". The Road to Laser Typesetting of Chinese Characters Just like Tang Monk's Journey to the West Difficulties Especially when facing the most difficult Digital storage of Chinese characters To make computers accept Chinese characters Easier said than done Western writing has only 26 letters The number of Chinese characters is huge Hundreds of times more than English And the printed Chinese characters There are also changes in font size To build a Chinese character library This is related to the Computer development level Totally inconsistent This became the Recognized world problem Screenshot of the video "Contemporary Bi Sheng - Wang Xuan". The days of tackling key problems are difficult But it is difficult To achieve great things In order to overcome the difficulties of laser typesetting technology Those Years He gave up almost all his holidays. He pondered the stroke pattern of each Chinese character Discovery of Chinese characters Regular strokes such as horizontal, vertical and fold It is composed of irregular strokes such as left, right, right, and right. He based on Chinese characters Starting, ending, turning, etc. and the starting position of the strokes, etc. Combined with mathematics Knowledge of computer hardware and software Invented high-resolution fonts High-rate information compression technology and high-speed recovery method Be the first to design a corresponding dedicated chip The first use in the world "Parameter Description Method" Describing stroke characteristics And obtain China and Europe Invention Patent In 1994, Wang Xuan and his wife Chen Kunqiu looked at the typesetting film output by the Chinese character laser typesetting system. Image source: Xinhuanet These achievements have created A new era of Chinese character printing It triggered the Chinese newspaper industry and printing and publishing "Say goodbye to lead and fire, and step into light and electricity" This technological revolution Completely transformed our country Lead printing technology that has been used for hundreds of years my country's traditional publishing and printing industry In just a few years From typesetting Straight to laser phototypesetting After decades of traveling in the West The road to technological transformation has just been completed Recognized as After Bi Sheng invented movable type printing The second revolution of printing technology in China 【A Heart Chasing Dreams】 The Development of Chinese Character Laser Typesetting System There are some little-known details August 1974 Approved by Premier Zhou Enlai China has started a The scientific research project named "Project 748" The project is divided into three sub-projects Chinese character communication, Chinese character information retrieval and Chinese character precision typesetting With Wang Xuan's insistence Develop products that the West does not have yet The fourth generation laser typesetting system Successfully "squeezed" into the "Project 748" Wang Xuan is checking the newspaper film produced by the Chinese character laser typesetting system. July 27, 1979 In the computer room of Peking University Researchers developed their own Laser phototypesetting system One sheet was outputted at a time Composed of various font sizes Complex layout Eight-page newspaper sample paper The header is "Chinese Character Information Processing" Six big characters This is the first time that laser imagesetters have been used Output of Chinese newspaper layout It is the fourth generation Major achievements in laser typesetting systems In January 1994, Peking University Founder Group successfully developed a high-end color publishing system. Wang Xuan (left) introduced this scientific research achievement. Image source: Xinhuanet July 1981 my country's first Computer Chinese Character Laser Typesetting System Principle Prototype Huaguang I State Computer Industry Administration Held jointly with the Ministry of Education Ministerial appraisal 1992 Wang Xuan successfully developed The world's first Chinese color phototypesetting system On November 6, 1995, UNESCO Deputy Director-General Badran presented the award to "UNESCO Science Award" winner Wang Xuan (right). Image source: Xinhuanet Wang Xuan Describing stroke characteristics using "contour + parameters" Solved the Chinese character glyph information The challenge of computer storage The rise of my country's newspaper industry and the technological revolution in printing and publishing Let today's Chinese mobile phone text messages and email became a reality Let our ancient Chinese characters Glow in new life Source: Communist Youth League Central Committee Editor: Yu Feiyue Proofreading丨Luo Yihe Proofread by Jia Wencheng On-duty editor: Dong Junjie |
