摘　　要：硼同位素中10 B因其对热中子吸收截面很大,在核电、军事装备、现代工业、及医药等方面应用广泛。硼同位素的分离方法有很多种,本文主要介绍了激光法分离硼同位素的理论原理及国内外研究进展。激光法是通过吸收光谱中的同位素位移进行同位素分离。在目前的研究方法中,主要采用强激光选择性激发含硼目标分子,通过激光辅助缩聚延迟法进行多模块化分离硼同位素有望实现工业化。10 B of boron isotopes has a large thermal neutron absorption cross section,it is widely used in nuclear power,military equipment,modern industry and medicine.There are many ways to separate boron isotopes,This paper mainly introduces the theoretical principle of laser separation of boron isotopes and the research progress at home and abroad.The laser method is to separate isotopes through the displacement of isotopes in the absorption spectrum.In current research,the target molecules containing boron are excited selectively by high power laser,it is expected to be industrialized to separate boron isotopes by the laser assisted retarded condensation method.
