摘　　要：张青莲教授是中国科学院院士,我国同位素化学的奠基人。本文介绍他在90高龄之际在原子量新值测定方面所取得的杰出成就。从1990年代初以来,他主持一个科研小组采用质谱法,实施了测定10项原子量新值的长期计划。至2001年7月已经有InI、r、Sb、Eu、Ce、Er、Ge、Dy和Zn等9个原子量新值被国际纯粹与应用化学联合会(IUPAC)的原子量与同位素丰度委员会(CAWIA)正式确定为原子量的国际新标准;另外一个Sm原子量新值也于2005年被国际组织确认。Professor Chang Tsinglien （Zhang Qinglian）, an academician of Chinese Academy of Sciences, born in 1908, is the founder of isotopic chemistry in China. This paper introduces his outstanding contributions to the determination on new values of atomic weight when he was 90 years old. From the beginning of 1990s, he led a research group for a long term project to determine the new values of atomic weight by using mass spectrum technique. The new international standards of atomic weight of 9 elements determined by Chang＇s group including In, It, Sb, Eu, Ce, Er, Ge, Dy and Zn had been set up by CAWIA of IUPAC till July 2001, and that of another element Sm was set up in 2005.
