摘　　要：本文介绍了一种自行设计与研制的可用于研究激光等离子体反应的质谱仪。它以高能量密度的脉冲激光作用于固相的反应体系,产生高温等离子体,以两台飞行时间质谱计同时记录激光等离子体反应产生的正负离子质谱。作为反应研究的实例,本文还介绍并讨论了硫、磷与银、铌等简单二元体系的反应结果。A home-made mass spectrometer specially designed for studies of laser plasma reactions is in- troduced in this paper. In this instrument, pulsed laser beam of high energy density is focused on the sample which consists of the mixed reagent in solid state. The mass spectra of both positive and negative ions in laser plasma are recorded on two time-of-flight mass spectrometers coincidently in situ. As the samples of the reactions, the experimental results of reactions among sulfur, phosphrous, silver and niobium are described. Breif discussions and analysis of these results are also presented in this paper.
