摘　　要：针对目前部分核物理实体实验受限制的问题,笔者开发了“伽马射线综合实验”虚拟仿真实验系统。基于Geant4和Unity3D,该系统对原有教学大纲中伽马射线能谱测量、伽马吸收系数测量以及康普顿散射效应实验内容进行了还原和拓展,引入了康普顿效应探伤模块,满足从普通本科生的基本理论知识的学习到专业研究生的科学探究、科研训练的多层次需求。本文对所包含的实验模块进行了简单介绍,对康普顿效应探伤模块进行了详细介绍,并总结了本实验用于多层次教学的效果。For the limitation of some nuclear physics experiments,a virtual simulation experiment system of“gamma ray comprehensive experiment”is developed.Based on GEANT4 and Unity3D,the system restores and expands the experimental contents of measurement of gamma ray spectrum,measurement of gamma absorption coefficient and measurement of Compton scattering in the original syllabus,and introduces a defects inspection by Compton gammarays backscattering,which meets the multi-level needs from the basic theoretical knowledge of ordinary undergraduates to the scientific exploration and scientific research training of professional postgraduates.This paper briefly introduces the experimental modules are briefly introduced,with a detailed introduction to the defects inspection by Compton effect module,and finally summarizes the effect of this experiment in multi-level teaching.
