Entrusted by the Central Committee of the Communist Party of China, Li was in charge of investigating radio transmitter-receiver.In the Spring of 1929, he successfully developed the first batch of radio transmitter-receivers for the Communist Party.The Central Committee used them to communicate with cities and Chinese Soviet Areas.He worked in the Academy of the Ministry of Posts and Telecommunications of the Soviet Union in 1931, mainly studying long distance telecommunication.He studied and manufactured high power radio transmitters.Based on physical analyses, he studied various types of radio transmission antenna and obtained a formula for calculating rhombus transmission antenna.He also investigated calculation formulae of other types of antenna, such as antenna with ultralow level.He was in charge of the telecommunication work in the Liberated Areas in 1947 and led the development of high power transmitters and directional antenna.After the founding of the P.R.China, he was in charge of taking over some broadcasting stations of the Kuomintang regime and the development of high power broadcasting transmitters and broadcasting antenna in medium wave.

He became Member of the Chinese Academy of Sciences in 1955.

李薰1913.11.20～1983.03.20

物理冶金學家。湖南邵陽人。1936年畢業(yè)于湖南大學。1940年獲英國雪菲爾德大學冶金學院哲學博士學位，1951年獲冶金學科學博士學位。中國科學院副院長、中國科學院金屬研究所研究員。在飛機引擎主軸斷裂原因的研究中，發(fā)現(xiàn)鋼中氫脆的奧秘和規(guī)律，證明了鋼的內部發(fā)裂是由于氫的存在引起的，并以擴散、溶解度和鋼的結構等關系，闡明了不同溫度下鋼材尺寸大小、時間與鋼中氫含量的關系，對世界各國鋼鐵技術一直有著非常重大的影響。在他的領導下中國科學院金屬研究所開拓了鈾冶金、鑄造高溫合金、難熔金屬、高溫物理性能測試、稀土在鋼中應用等研究領域并取得許多重要成果。為中國第一顆原子彈、第一顆重返地面人造衛(wèi)星、第一架超音速噴氣飛機、第一艘核潛艇提供關鍵材料做出了重要貢獻。

1955年被選聘為中國科學院院士（學部委員）。

Physical metallurgist.Born in Shaoyang, Hunan Province.Graduated from Hunan University in 1936.Rcecived Ph.D.from Sheffield University, UK in 1940 and D.Met.In 1951.Research professor and first director, Institute of Metals Research and vice president, Chinese Academy of Sciences.

During his early years in UK, Li discovered the secrete and the principle of hydrogen brittleness in steels when he conducted a research project of seeking out the cause of an accidental crack in aircraft engine shaft.He proved that the internal hair-crack in steel is due to the existence of hydrogen in the material.From the view point of diffusion, solubility and structure of steel, he expounded the relationship of time-temperature-size and hydrogen content in steel products, which produced great impact on the iron and steel technology in the world and made him the acknowledged pioneer in this field.Under his leadership, scientists in the Institute of Metals Research studied uranium metallurgy, high temperature cast alloys,refractory metals and alloys, measurements of physical properties of materials under high temperature cast alloys, refractory metals and alloys, measurements of physical properties of materials under high temperature, and application of rare earth in steel and so on.Several important achievements have been made, such as the increase of the yield and the improvement of the quality of steel production,the construction of Wuhan and Baotou iron and steel plants and the establishment of the alloy steel system of Chinese grade.He made great contributions to the research and development of key materials used in the first atomic bomb, first recovery satellite, first supersonic aircraft and first atomic submarine in China.

He became Member of the Chinese Academy of Sciences in 1955.
