The most commendable work of the National Translation and Translation Center is its leadership and promotion of the unification of translations of scientific terms. As the amount of literature translation in various disciplines increases, many knowledgeable people have long recognized the importance of unifying translation names: "It is difficult to name things that are translated. And in science, there are especially many new names. If the noun is uncertain, science will not be able to "("Science" published in 1915). In the early days, the unification of translation names was mainly carried out by individual scholars or academic groups. After the establishment of the National Translation and Translation Institute, it became more independent in compiling, unifying, and promoting translations. The Institute formulated We compiled a detailed translation plan, established various subject groups of the Translation Committee, and worked closely with various folk societies and associations to complete the unified translation review and approval work in 80 subject areas of natural sciences and social sciences to varying degrees. The unified nouns published and published as books by the Compilation and Compilation Library include "Principles of Chemical Nomenclature", "Pharmaceutical Nouns", "Astronomical Nouns", "Physical Nouns", "Mineralogical Nouns", and "Bacteriology and Immunology Nouns" , "Mathematical Terms", "Sociological Terms", "Economics Terms" and more than 20 kinds. These tasks have played a huge role in the process of translating and disseminating foreign advanced scientific knowledge and developing our country's science and technology. Many scientific translations approved and published at that time are still in use today. A giant in unifying translations in the field of natural sciences and the greatest compiler and reviewer of translations of natural sciences in China. It is indispensable for the development of China's natural sciences and social sciences. Endow New Chinese with inestimable value and enable scholars with Chinese language skills to stand at the top of world competition.

Li Yan (1892-1963) was born in Minhou, Fujian (now Fuzhou City). Academician of the Chinese Academy of Sciences, historian of mathematics, Chinese and Western mathematician, expert on the history of ancient Chinese mathematics, and a pioneer in the history of Chinese science. Li Yan is a well-deserved founder of the discipline in the field of Chinese mathematics history research. In 1912, he was admitted to the Tangshan Road and Mine School (now Southwest Jiaotong University) to study civil engineering. He was a classmate and close friend of Mao Yisheng. Based on a large amount of historical data collection, he has done a lot of research on the history of ancient Chinese mathematics and has written many books. He is one of the pioneers of this research. He completed self-study college courses in civil engineering and mathematics through correspondence education at home and abroad; at the same time, he began research on the history of Chinese mathematics. According to information from the Rare Book and Manuscript Library of Columbia University, between 1915 and 1917, not long after Li Yan started researching the history of Chinese mathematics, he corresponded with the famous historian of mathematics D.E. Smith many times and drafted an outline. , the book was titled "History of Chinese Mathematics" and was translated into English by Mao Yisheng, who was studying in the United States at the time, and handed over to Smith. However, this writing plan ultimately failed to materialize due to various reasons. After that, "Remaining Records of the History of Chinese Mathematics" was published in 1917, and "A Survey of the Origin of Chinese Mathematics" was published in 1919. Throughout his life, he published more than 100 papers and more than ten monographs. It can be said that Li Yan is a well-deserved founder of the discipline in the field of Chinese mathematics history research. From the 1920s to the 1930s of this century, Li Yan compiled volumes 1-4 of "Zhongsuan History Series" (The Commercial Press, 1933, 1935, 1947). It took more than 30 years until the final compilation of "Zhongsuan History Series" can be regarded as the most effective work of his life. These include fraction theory, research on Pythagoras' theorem (Pythagorean theorem), square zero reduction, Dayan's method of finding one, vertical and horizontal graphs, research on Pascal's triangle (Jia Xian's triangle), equation theory, Various articles on series theory.

He carried out a series of structural modifications on these compounds and conducted detailed studies on the relationship between the structure and function of these compounds. His work created a new research field - the study of the relationship between structure and function. In 1956, under the leadership of the Ministry of Health of the Military Commission, he founded China's first isotope application training class, and the first batch of nuclear medicine backbones went nationwide from here. In China, he created isotope marker synthesis, liquid scintillation measurement, radioimmunoassay analysis, medical activation analysis, stable nuclide medical application, radioimmunoassay imaging and other technologies; in his systematic research on thyroid hormone (TH), he unraveled the mechanism of TH action. Some incomprehensible mysteries have been solved and remarkable results have been achieved. He achieved breakthroughs one after another in his research on the suddenly emerging nuclide tracer technology. In the late 1970s, he proposed the use of stable nuclides as tracer atoms in the field of experimental nuclear medicine for biomedical and pharmaceutical research. He trained the first batch of radiolabeled compound workers for China. Especially when he was the director of the Labeled Compounds Research Laboratory at the Institute of Radiation Medicine, Chinese Academy of Medical Sciences, under his leadership, a total of more than 100 labeled compounds were synthesized and produced from 1959 to 1979, which greatly It has promoted the development of scientific research in many basic and clinical disciplines in China. He established the Positron Emission Tomography (PET PECT) Center. Technologies such as isotope marker synthesis, liquid scintillation measurement, radioimmunoassay analysis, medical activation analysis, stable nuclide medical applications, and radioimmunoassay imaging have been created in my country. Nuclear medicine is a science that uses nuclear technology to diagnose, treat and study diseases. It is not difficult for ordinary people to know about PET, SPECT, thyroid function meter, nephrograph, radioactive activity meter, as well as equipment such as gamma knife, post-loading treatment machine, simulation positioning machine, linear accelerator and other equipment used for radioactive treatment. Understand the important position of nuclear medicine in modern medicine. The comprehensive strength of China's nuclear medicine pioneered by him has ranked among the world's advanced ranks and has become a leader in the field of nuclear medicine in Asia.
