摘　　要：为解决核物理教学实验安全难题,设计了虚实结合的核物理教学实验仪器.采用先进的虚拟放射源、可重构理念和技术,通过虚实结合开发了放射源模拟器、教学通用型的多功能数字多道和实验控制系统,可对放射源及探测分析系统仪器及参量进行灵活的重构配置,拓宽传统核物理实验教学的内容.利用该系统可开设放射性测量的统计规律、闪烁体探测器与γ射线吸收、康普顿散射等10余个实验项目,学生可以重构实验系统,研究射线(粒子)与物质相互作用的规律.This comprehensive experiment system was a kind of instrument integrated with virtual-reality technique,which was designed to solve the safety problem of nuclear physics experimental teaching.Based on advanced virtual radiation source,reconfigurable concept and techniques,a radiation source simulator and a versatile digital multichannel and experimental control system through the combination of virtual-reality technique were designed.The equipment and parameters of radiation source and detection and analysis system could be flexibly reconfigured,and the content of traditional nuclear physics experimental teaching was broadened.More than 10 experimental projects,such as statistical law of radioactivity measurement,scintillator detector andγray absorption,Compton scattering and so on,could be performed using this system.Furthermore,the experiment system could be reconstructed by students to study the interaction between radiation(particle)and matter.
