Guan's early experience

1943, just turned 15 years old, he participated in the anti-Japanese underground work led by the * * * production party in Digang Middle School, distributing leaflets and posting slogans. From 65438 to 0944, he was the editor-in-chief of the underground publication Cold Star, and published more than ten issues successively, opposing enslavement education, awakening students' national consciousness, and exposing shameless and criminal acts of satirizing the enemy and puppet. 1945 joined the China * * * production party as the branch director, and served as the chairman of the Suzhou-Anhui First Division Digging Hong Kong Youth Federation, the head of the Yellow Sea Troupe, and the chairman of Rudong Middle School Student Union. 1in the spring of 946, according to the organizational arrangement, 18-year-old Guan left his hometown to work in the Northeast Liberated Area.

/kloc-in the autumn of 0/949, Guan was sent to Harbin Institute of Technology to study, and served as the director of the political teaching and research section and a political teacher. 195 1 Guan was admitted to the physics department of Tsinghua University with excellent results. 1953 was sent to the former Soviet Union to study abroad, and studied in the Physics Department of Leningrad University, Tbilisi State University and Moscow University successively, majoring in low temperature physics. During his study in Moscow University, due to his outstanding achievements, he was sent to the Institute of Physics led by the famous physicist Peter Kapicha (who later won the Nobel Prize in Physics) to complete his graduation thesis. He discovered the "inverse Kapicha thermal resistance" through clever experiments. 1958, he read his graduation thesis at the all-Soviet conference on low temperature physics, which was staggering. He graduated early, was recommended by the school, and was selected as a graduate student of the Institute of Physics by Peter Kapicha, director of the Institute of Physics of the Soviet Union. He wrote his research results into a paper "Study on the Temperature Discontinuity at the Interface between Solid and Superfluid Helium", which became a classic in this research. Guan graduated from 1960, and received a doctorate from an associate professor in the Soviet Union (equivalent to a doctorate in Europe and America).
