摘要: 主要以基于LabVIEW设计的物理虚拟仿真实验——“测量电阻的伏安特性曲线实验”和“伏安法测电阻实验”为例,说明运用LabVIEW设计物理实验的过程和方法.该仿真实验系统界面生动形象,交互性强,能实时对实验测量结果进行测绘.学生能直观地观察到不同参量或测试方法对测量结果的影响,从而有利于加深对相关知识点的理解.Abstract: In this paper,the physical simulation experiment system,which includes both the experiment"measuring the volt-ampere characteristic curve of the resistance" and the experiment-"resistance measurement with voltammetry",is designed by using LabVIEW.The process and method for designing experiments with LabVIEW are illustrated.The simulation experiment system has a visual interface with strong interaction,and can real-time analyze the experimental measurement results.Based on the system,the influence of different parameters or test methods on the measurement results can be observed intuitively,which is helpful for students to further understand the relevant physical knowledge.
