摘　　要：提出了应用MonteCarlo程序模拟MRPCγ射线灵敏度的方法。模拟MRPC对0.03～100MeV、垂直均匀源和各向同性源的γ射线的灵敏度。该方法可以用来计算不同实验环境中不同γ射线源时,MRPC探测器的灵敏度。为研究如何消除γ射线本底对测量结果的影响提供参考。A method of simulating MRPC ( Multigap Resistive Plate Chamber) γ sensitivity has been developed using Monte Carlo program. γ sensitivity is calculated as a function of γenergy from 0.03to 100 MeV and various γ source such as parallel or isotropic sources. This method can be used to evaluate MRPC γ sensitivity in different environment and γ ray sources. It can also be used to eliminate the disturbance of γ ray background to experiment results.
