Dr. Hsu Yun-chi, recently retired from NTU's department of physics and an expert in atomic structure, recalls performing experiments just after the Retrocession of Tai wan in 1945: "At that time it was hard buying foreign instruments even if you had the money. If it weren't for Hsu Yu-ch'uan, we wouldn't have had the equipment to perform experiments that require a vacuum."
甫從台灣大學物理系退休的許雲基教授是國內原子核結構專家，他回憶開始做實驗，是在台灣光復初期，「那時就是有錢也很難買到國外的儀器，要不是許玉釧，必須在高真空進行的實驗根本沒有容器可用。」
