摘要
通过实验证实Ｇ－Ｍ计数管实验中新旧计数管对计数管的坪曲线和分辨时间的影响，研究放射源放在不同位置与计数管计数的关系，分析自动定标器阈值电压的选择方法．
By experiment,the influence of new and used tube to level curve and resolving time in the GM experiment has been tested.Studies the relation between the count of tube and the position of radioactive source,and the mothed of selecting the threshold voltage of the automatic scaler.
