微波炉炉腔阻抗的计算机辅助测量

COMPUTER AIDED IMPEDENCE MEASUREMENT OF CAVITY INMICROWAVE OVEN

本文介绍了一种用计算机辅助测量微波炉炉腔阻抗的方法.该方法利用两个“标准件”(匹配负载和短路器)和一根同轴电缆,可测出炉腔的复阻抗.文中还对该方法进行了误差分析及讨论.测量结果与松下公司的实测数据进行了对比,符合较好,证实本方法是有实用价值的.

In this paper, a computer aided method to peasure the impedence of cavity in microwave oven is reported. By means of this method with two standard devices ( short circuit and matched load ) and a coxial cable, the complex impedence of oven cavity can be obtained. The error of this measurement is discussed. Comparing the experimental data from. The National Corporation with ours, it was found that they are coincided with each other very well. It is proved that the method presented here is practical and useful.
