He Yizhen (1910-2008), one of the outstanding knowledge women who are active in the Chinese physics community in the 1950s and 1960s, and together with the sisters He Zehui and He Zeying, they enjoy the "He's Three Sisters" in China. Her life is closely linked to my country's modern scientific cause, which reflects the important contribution of Chinese scientific and technological women under the guidance of patriotism and make every effort to the development of my country's scientific cause and the promotion of modernization.

He Yizhen was born in Beijing in 1910. He Yizhen's father, He Cheng and his aunt Wang Junjiu, were all kinds of people who participated in the 1911 Revolution. Grandma Xie Changda was an outstanding female educator in modern education in modern Chinese education and advocate and practitioners of the liberation campaign of Chinese women. Due to the devastation of feudal etiquette, Xie Changda painted the dregs of "women's talents is virtue". With the sisters He Zehui and He Zeying, they all come from this well -known girl school. Under the influence of good family education, the "He's Three Sisters" has developed a self -esteem and self -reliance character since childhood.

In 1930, He Yizhen graduated from the Jinling Women's College in Nanjing. In 1931, he set foot on the road of ocean -stayed in the United States with the help of Wu Yifang, the principal of Jinling Women's College, and entered the Department of Chemistry, Mengchohhhuma Women's University in the United States. After two years of hard work, He Yizhen obtained a master's degree with excellent grades, and obtained the Babber scholarship under the recommendation of the school, and went to the University of Michigan to study for a PhD. In the 6 years of studying abroad, He Yizhen studied hard, across the two basic disciplines of physics and chemistry, engaged in atomic spectrum research on transitional elements, and in the research topic of atomic spectrometry of rare earth elements, the spectral line of research was visible from visible light to visible light to The first person with ultraviolet lighting and publishing her research results established her academic status in world spectral research.

In the 6th year of the United States, He Yizhen never forgot what his father had said to them: "I want to give you a family member to send you out, learn the foreign strengths, and return to China." In May 1937, He Yizhen obtained a doctorate degree in Physics Philosophy. In July, he learned that he returned to the motherland immediately after the domestic Luogouqiao Incident. During this special period of invasion and fire of strong pirates, He Yizhen, who was only 27 years old, gave up the promising trip to Europe and the United States. He resolutely chose to return to his homeland and have difficulties with the motherland and relatives. The young Chinese women are reflected.

From 1938 to 1941, He Yizhen ran around in Shanghai, Peiping, Nanjing and other places with his family during the war, and taught at Beijing Normal University, Yanjing University, and Soochow University. In July 1941, Mr. Ge Tingxuan, a member of the Chinese Academy of Sciences and a well -known metal physicist later, married, and then the two went to the United States to study again with the great ambition of "scientifically saving the country". After the founding of New China in 1949, He Yizhen broke through the resistance with her husband, gave up the good treatment abroad and returned to the motherland, and dedicated to the Chinese science cause. He Yizhen applied his theoretical research to the construction of the New China metallurgical industry, and successively carried out a number of studies such as the impact of the alloy steel tissue structure on spectral analysis, the spectrum analysis methods of trace earth elements in high -speed steel and alloy steel. The blank of spectral analysis has solved the needs of production, and also cultivated a large number of backbone talents for the motherland. Its research papers published in combination with production practice have been widely recognized by international peers. After the 1970s, He Yizhen led students to conduct a lot of research on the mechanical properties and structural stability of metal glass, and the earliest development of the field of amorphous physics and metal glass in my country.

In addition to daily scientific research and the growth of young scientific talents, He Yizhen also actively participated in various social activities. Emphasized national activities raised good funds. He Yizhen is not only an outstanding scientist who pursues truth and rigorously studying, but also a great social activist who is selflessly dedicated and affectionate. It is a model of self -reliance and self -reliance in our generations.
