杨承宗对中国放射化学的贡献

Yang Cheng-zong’s Contribution to the Development of Radiochemistry in China

杨承宗(1911—2011)是我国著名的放射化学家、教育家,我国核燃料工业的开拓者之一,新中国放射化学学科奠基人。目前关于杨承宗的学术贡献多散见于一些回顾和介绍其生平事迹的文献之中,尚乏深入讨论。本文系统梳理了杨承宗不同时期的主要学术工作,认为他对我国放射化学的贡献有二:一是在放射化学学科的建立和长期发展过程中起到了关键作用;二是带领科技人员解决了天然铀生产过程中的各种放射化学及其工艺问题,为我国铀工业的建立提供了重要的技术支撑。最后,结合中国放射化学的发展历程对杨承宗的学术生涯作了简要探讨。

Yang Cheng-zong(1911~2011)was a famous radiochemist and founder of radiochemistry discipline and one of the pioneers in nuclear fuel industry in China.This paper systematically introduces his main academic work in different periods,and points out that he has made two contributions to radiochemistry in China:first,he played a key role in the establishment and long-term development of the discipline of radiochemistry;the second is to solve various radiochemical and technological problems in the production of natural uranium,providing important technical support for the establishment of China’s uranium industry.Finally,his academic career is briefly discussed in combination with the development of Chinese radiochemistry.
