Academic contribution of wisdom

1954, Yellow River Instrument Factory was merged into Shanghai Electric Meter Factory, served as the deputy chief engineer of Shanghai Electric Meter Factory, and established the central laboratory. The research results of the long-term stability of the German timekeeping crystal clock were brought back to China for further research, and the research of the timekeeping crystal clock for astronomy was organized and led.

Since then, he has taken the lead in organizing digital research on instruments and promoting the application of digital instruments in China. Then, in the absence of a perfect power standard and transmission system in China, under the leadership of the State Bureau of Metrology, he negotiated with the Shanghai Bureau of Metrology and other units to establish a set of transmission physical standards such as standard resistors and standard batteries in Shanghai, which created conditions for the production of urgently needed electrical instruments. He first developed the key material of instruments-manganese-copper alloy. In order to break the monopoly of importing high-priced Mn-Cu alloy materials from the Federal Republic of Germany, he suggested that Shanghai Science and Technology Commission organize joint research, and with the consent of the Municipal Science and Technology Commission, it was initially determined that Shanghai Tongren Alloy Factory would be responsible for advanced Mn-Cu alloy, and the instrument research room of Shanghai Electric Meter Factory would be responsible for high-precision reliability measurement of Mn-Cu alloy resistance elements and research of special instruments and equipment. By comparison, its standard resistance performance has reached the international advanced level, which has laid a solid foundation for the manufacture of precision resistors and measuring instruments in China.

At the beginning of the founding of New China, the state discussed the development plan of science and technology in the first five-year plan, and Premier Zhou Enlai signed an invitation letter for him to come to Beijing to discuss the development plan of science and technology in China. Since then, he has participated in the work of "1956" and "1962" in China twice, and was specifically responsible for planning the development of instruments and meters in China.

1964 In May, after the establishment of Shanghai Electric Instrument Research Institute (predecessor of Shanghai Instrument Research Institute), Branch served as deputy director and chief engineer of the Institute.

Shortly after the Cultural Revolution, he was persecuted, labeled as "reactionary academic authority" and put in a "bullpen".

In his spare time, the diligent scientist came up with a research idea on slogans and posters plastered all over the wall: "Can Chinese characters become a regular code? If successful, sending a telegram can save a lot of things, especially the application of Chinese on computers is more difficult. If only we could invent a way to input keys without memorizing words! " He thought: "There are many Chinese characters, with more than 4,000 commonly used, while Latin is very simple, with only 26 letters. Can Chinese characters be replaced by 26 Latin letters? " In the bullpen, he didn't even have a dictionary at hand, but he looked at the keeper angrily and scolded him. With the knowledge of teaching Chinese and studying Chinese characters in German universities, he began to study the Chinese character codes on the lid, floor and wall of teacups. This "cultural revolution" became his opportunity to enter a new field of scientific research. In a cell with an area of only six square meters, his scientific thinking gallops in the mysterious world of Chinese character coding.

1September, 969, Branch came out of the isolation room and was supervised, from sweeping the floor and cleaning the lathe, and later served as a waste warehouse administrator. He also took the small warehouse as his "laboratory" and engaged in his research on Chinese character coding. He borrowed Mr. Lu Xun's "self-mockery": "Hide in a small building and become unified, regardless of spring, summer, autumn and winter." In the process of painstaking research, we finally got the relevant information from abroad. According to the data, since 1950s, many experts and scholars in Japan, the United States, Britain, France, Australia and Taiwan Province Province of China can easily input foreign pinyin characters into computers by selecting 20-30 letters of "0" and "1". However, in order to let Chinese characters enter the computer, it took nearly 20 years, painstaking efforts, racking their brains, conceiving many coding methods and designing several keyboards. However, for pictographic Chinese characters with unique shapes, it has become a "world problem". Zhi carefully studied and summarized the advantages and disadvantages of foreign coding methods, created a method to break the single decomposition of Chinese characters, comprehensively analyzed the relationship between the sound, shape, pen and pinyin of Chinese characters, coded with 26 Latin letters, and represented a Chinese character with 4 letters, formulated simple rules, and solved a shortcut for inputting Chinese characters into electronic computers. So, he took a Xinhua Dictionary as a companion, coded all 8500 words in the dictionary, and filled in a card for each word, from which he explored and solved the law of duplication. The 8500-word Chinese character coding is his painstaking effort! After six years' efforts, the first draft of "Reading Words and Codes" was completed in the autumn of 1974, which was a pioneering achievement in China at that time. 1995165438+1October 3, Wen Wei Po wrote: "The inventor of the first Chinese character input code is called Zhi, so this code is called Zhu Code. Open sesame is the mantra of acquiring wealth in the mountains in ancient Arabic mythology, and "matching code" opens the road of combining modern computer technology with traditional culture in China. "Opening the door with matching code will open the door to Ma Benteng".

The key to the coding method of Chinese characters created by Zhi is to code with 26 Latin letters, and four letters represent one Chinese character. The rules are simple and easy to master. For example, the word "Lu" can be divided into four parts: mouth, plug, text and mouth. Take the first letter of the radical pinyin, that is, the code KZWK that constitutes "Lu". Because the code of each Chinese character is fixed, it brings great convenience to the storage of computers and the application of soft devices. The keyboard for coding consists of 26 Latin letters, which can be used for typing in Chinese or western languages, and can also be used for teleprinters in western languages. Because each Chinese character consists of four letters, you only need to press the key four times, while each western character consists of six or seven letters on average. You need to press the key six or seven times, so the typing speed of Chinese characters is faster than that of western languages. In 1977, the service desk of Shanghai Telephone Bureau "1 14" successfully converted the Chinese characters of the user's company name into a kind of information and stored it in the computer. According to the user's request, the operator presses the key and automatically answers the searched telephone number through the electronic computer. At the end of 1976, his scheme of "reading characters and recognizing codes" was completed.

1977, under the leadership of the Shanghai Municipal Science and Technology Commission, led the formation of the Chinese character information processing system battle group. After several large-scale discussions, technicians from more than 20 units unanimously agreed to adopt the "support code" Chinese character coding method. With everyone's joint efforts, the Chinese character coding input system was successfully developed in early May of 1978. "Reading Chinese character codes" is a golden key, which opens the door for Chinese characters to enter the computer. Because of his outstanding contribution to Chinese character coding, 65438-0977 was awarded as an advanced worker in Shanghai.

After that, Zhi and his assistants designed a compact keyboard similar to the teletypewriter used in computers at that time in June 1978+00. The input speed of Chinese characters is so fast that you can type while reading the manuscript. In this way, Chinese characters can be input into the computer as conveniently and quickly as western languages. The success of the experiment is the first sign of the arrival of the information age in China.

After the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China, he was completely rehabilitated and successively served as the chief engineer, deputy director, director and honorary director of Shanghai Institute of Instrumentation. In June, 1980, 1 1 was elected as an academician of China Academy of Sciences.

In order to push forward the existing achievements, he accompanied the leader of the First Machinery Department of China to visit the Federal Republic of Germany in April 1979, and reached a technical cooperation agreement with the Olympia company of the Federal Republic of Germany, combining the coding method of "reading words and codes" with the microcomputer and inkjet printing technology of Olympia company, and developed China's computer typewriter. During June and July of 1980, a second prototype with a capacity of 6000 words was manufactured and exhibited in Beijing in June of 198 1. China's computer typewriter is characterized by multi-function and multi-purpose. With 26 letters, you can input Chinese, English or Latin fonts or handle Chinese and English characters at the same time. Its characters are printed on paper by electronic computer through information processing and print head, which is silent and fast. Because it is equipped with microcomputer equipment, floppy disk, screen, temporary memory and so on. You can also store words on a magnetic card. A skilled typist can type 60 ~ 80 words per minute. At that time, ordinary old typewriters could only type 30 words. Generally, it only takes about 10 days to master the operation, and it takes about one month to practice to reach proficiency. The emergence of Chinese computer typewriter is a breakthrough and innovation in Chinese typing, but it is by no means a typewriter in the general sense. It is attached with a standard computer interface as the input terminal equipment of the computer, which is suitable for office command system, economic information, telex communication, meteorology, banking, railway, aviation and news departments.

In order to meet the needs of market economy, China and Germany decided to mass-produce China's computer typewriters on the basis of two trial-productions. 1On July 6, 982, the new Haotai System Co., Ltd., which is responsible for foreign marketing, was established in Hong Kong. Under the planning of this company, 10 1 1 China computer typewriter held trade fairs and seminars in Hongkong, which achieved a sensational effect. Zhi gave a special lecture on "Principles of Literacy and Code Recognition" and "Chinese Computer Typewriter" at the seminar. More than a dozen newspapers, radio stations and TV stations in Hong Kong introduced and publicized it, praising it: "It's amazing that computers can type square characters and read codes."

At the same time, various levels of China Information Research Association have been established. Since 1980, Zhi has been elected as the vice chairman of China Chinese Information Society, the chairman of China Chinese Character Information Processing Research Society and the chairman of Shanghai Instrumentation Society. In order to accelerate the popularization and application of electronic computers in China, Shanghai Institute of Instrumentation has set up a Chinese character information processing laboratory, which uses the method of "recognizing characters and codes" as software to carry out research on Chinese character generators, recording equipment, display terminals and general Chinese character databases. During the period of 1983, Shanghai Institute of Instrumentation provided computer Chinese character information processing technology and equipment for more than 50 domestic units, which were applied to posts and telecommunications, communications, government agencies, universities, industrial and mining enterprises, scientific and technological information, books and archives, sports and other departments and industries, marking that computer Chinese character information processing in China has entered the stage of application and promotion.

Influenced by China's ancient poems and books since childhood, Zhi has the traditional moral qualities of patriotism for the people, thrift, honesty and self-discipline, solemnity and self-improvement. After living in Germany for 12 years, the rigorous and meticulous spirit of German experts and scholars has a great influence on him. The blending of eastern and western cultures has cast his strong character of self-improvement, overcoming difficulties and bravely climbing the peak. After the founding of the People's Republic of China, under the education of China's * * * production party, his fine moral character gradually sublimated, and his patriotism and the idea of serving the people were further carried forward. At the age of eighty, he gloriously joined the China * * * Production Party and realized his long-cherished wish.

Wisdom has strict self-discipline and integrity, and puts national interests above personal interests. Every time he visits abroad, he strictly abides by the financial laws and regulations of the country. In a leading position, he often commutes to work by bus at the age of 70. He never used his authority and social influence to benefit his children's relatives. For example, after the War to Resist US Aggression and Aid Korea broke out, he actively supported his only son to join the army. 1983, he also hopes to send his grandchildren to the places where the motherland needs them most. 1980, after he was elected as an academician of China Academy of Sciences, he declined various forms of "titles" from many units, but was willing to spare a lot of time to train students.

On the road of science, he is studious, quick-thinking and forward-looking, constantly tracking the pulse of scientific development and struggling at the forefront of scientific research. After returning from Germany, he devoted himself to the research and development of electrical instruments and meters, stubbornly making our electrical instruments and meters catch up from the backward state and reach the world advanced level. During the "Cultural Revolution", hunting involved Chinese character coding and Chinese character information processing. In this new field of scientific research, we found a new way and took the lead step by step. During his illness in his later years, he continued to learn from "word code" to "word code" to further improve the speed and quality of Chinese characters input into the computer.

He is honest, fair, pursuing truth and demanding progress. After the Third Plenary Session of the Eleventh Central Committee, he completely recovered his reputation and took the leadership position. He was generous to his persecutors during the Cultural Revolution. He said it was my long-cherished wish to join the China * * * production party! Soon, he submitted an application for joining the Party to the Party organization, which read: "According to the historical facts of our country and my own experience, I deeply feel that only the China Producer Party can lead the people of China to build a new socialist China." 199 1 02 may 12 years old, gloriously accepted as party member, the producer party of China.

Wisdom's life is a bumpy road, a successful road, a road from patriotism to belief in capitalism. While the Chinese character coding and Chinese character information processing of local chronicles were in the ascendant, from June 5438+0985 to June 5438+00, he was unfortunately bedridden due to stroke and hemiplegia. In the case of illness, he has been studying how to improve the speed of "branch code" entering the computer and reduce the bit error rate until his last breath.
