对GM计数管进行补偿是为了消除低能段能量的过响应影响,从而提高其灵敏度。如果通过试探实验来确定屏蔽层厚度与开孔部分尺寸,过程非常复杂。论文验证了一种简便的计算补偿条件的方法,并尝试通过软件假设分析来寻找合适的补偿条件,缩短实验周期,简化计算过程,最后通过对某GM管的能量响应实验数据来说明其准确性,并加入理论结果与实验结果进行对比,两种结果基本一致,均满足能量响应的要求。

The sensitivity of GM counter is to be improved by the method of energy compensation which is to re -duce the energy response effect at low energy region .If the shielding layer thickness and the size of hole part are determined by test experiment , the process will be very complicated .This paper verifies a simple method developed to calculate compensation conditions , also try to shorten the test cycle and simplify the calculation process by finding the right compensation conditions through software analysis base on hypothesizes , and finally prove the accuracy of the method by the energy response experiment of the GM counter .Comparing the calculat-ed results in theory with the experimental results , the two results are basically consistent and both of them meet the requirements of energy response .
