赵忠贤近三十年来一直从事低温与超导研究工作,并取得了多项重要成果。1974～1975年他在英国剑桥大学进修期间,发现第Ⅱ类超导体在磁通流动过程中,从非线性区到线性区过渡时,其转交点与临界电流呈线性关系。自1976年开始,他积极推动我国高 Zhao Zhongxian has been engaged in low temperature and superconducting research for nearly three decades and has made many important achievements. From 1974 to 1975, he studied in Cambridge University, UK, and found that the transition point of the second type superconductor has a linear relationship with the critical current during the flux transition from the nonlinear region to the linear region. Since 1976, he has actively promoted China’s high
