摘要

针对核物理教学实验安全难题，设计了基于 LabVIEW 的核衰变统计规律虚拟实验系统。采用算法模拟放射源、虚拟盖革-米勒计数器，实现核衰变统计规律测量;运用高斯拟合控件开发数据处理模块，完善虚拟实验系统。该虚拟实验系统完全仿真实际仪器，操作步骤与教学使用的实验仪器一致，可以高效地培养和锻炼学生的核物理实验能力，解决放射源保存限制，拓宽核物理实验教学在各学科中应用。

Abstract:

Aiming at the safety problem of nuclear physics teaching experiment，a virtual experiment of nuclear decay statistical law based on LabVIEW is designed．The virtual radioactive source and virtual Geiger Miller counter that simulated by algorithm are used to measure the statistical law of nuclear decay．Gaussian fitting mcontrol is used to develop data processing module and improves the virtual experiment system． The virtual experiment simulates the actual instrument completely and the operation steps are consistent with the experimental instrument used in teaching． Therefore，the virtual experiment system not only cultivates and exercises the ability of students’nuclear physics experiment effectively，but also breaks the limitation of radioactive source preservation and broadens the application of nuclear physics experiment teaching in various

disciplines．

Key words: statistical law of nuclear decay virtual experiment Geiger Miller counter LabVIEW
