摘　　要：通过应用计算机驱动步进电机控制驻波测量线的移动和可变衰减器的转动,结合放大电路及模数转换卡,实现了自动测量矩形波导管内微波的工作状态。同时将测量得到的数据通过计算机软件进行分析,利用编程模拟绘制出当前时刻TE10波的动画图像,即通过入射波与反射波的叠加,确定出当前为匹配状态、驻波状态或混波状态。通过计算机自动测量及动态反馈模拟,使实验效果、实验精度得到显著提高,实践应用效果甚好。By computer driving stepper motor with the help of amplifier circuit and A/D card,the movement of standing wave measuring line and the running of changing attenuator were controlled.Automatically measuring the stae of microwave in rectangular wave-guide was realized. In the same time,the data measured by software was analyaed.According to these data,the action images of TE10 wave transmitting in rectangular wave-guide was simulated.So we could confirm the maching state,standing wave state or blending state. By automatically measuring and dynamic feedback simulation,the precision and effect of microwave experiment were increased with good performance.
