摘　　要：本文报告了取样保持电子学系统用于宇宙线实验的一种触发判选方法.实验证明,这种方法能完整地收集随机出现的宇宙线事例信号的全部电荷,解决了由于取样门延迟打开所造成的信号电荷丢失问题.讨论了将这种方法用于北京谱仪宇宙线实验的问题.This paper presents a trigger scheme which has been used in a cosmic ray experiment with a sample-and-hold readout system. The experiment shows that this trigger scheme can fully collect the whole output signals of the wire chamber for the random cosmic ray events and get rid of the problem of signal loss caused by the delay of sampling gate. Some disscussions about using this scheme for cosmic ray test of BES are also provided.
