摘　　要：微波生成过程较难以直观展示,传统实验通常只能通过示波器观察微波电场和磁场强度的变化。这种方法在传统理论教学中往往难以帮助学生深入理解相关物理概念。为提高学生对实验原理的理解,设计并开发了微波实验的虚拟仿真实验室。通过该虚拟实验,学生可以完成预习、操作以及实验报告等教学任务,同时教师也能够在后台进行教学管理。微波实验虚拟仿真实验室借助先进的计算模拟技术,突破了真实实验在微观现象观察方面的局限。该平台不仅能够生动展示反射式速调管产生微波的原理,还能呈现波导中不同模式的电磁场分布,帮助学生更加直观地理解微波的传输原理与特性。五年教学实践的结果表明,微波实验虚拟实验室的应用显著提升了教学效果。The microwave generation process is difficult to display intuitively.Traditional experiments usually can only observe the changes in microwave electric field and magnetic field intensity through an oscilloscope.This method is often difficult to help students deeply understand relevant physical concepts in traditional theoretical teaching.To improve students'understanding of experimental principles,we have designed and developed a virtual simulation laboratory for microwave experiments.Through the virtual experiment,students can complete teaching tasks such as previewing,operating,and writing experiment reports.At the same time,teachers can also conduct teaching management in the background.With the help of advanced computational simulation technology,the virtual simulation laboratory for microwave experiments breaks through the limitations of real experiments in the observation of microscopic phenomena.This platform can not only vividly show the principle of microwave generation by a reflection klystron,but also present the electromagnetic field distribution of different modes in a waveguide,helping students understand the transmission principles and characteristics of microwaves more intuitively.The results of five years of teaching practice show that the application of the microwave experiment virtual laboratory has significantly improved teaching effectiveness.
