/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).
