摘　　要： 以典型的M20L微波炉为代表,采用计算机仿真技术,研究微波炉腔体的匹配问题。对微波炉实体建模和设置腔体内介质材料电特性参数,并进行了仿真研究,得到的结果与实际测试数据一致,验证了建模的准确性。在此基础上研究了微波炉腔体结构参数对匹配性能的影响,找到了影响匹配的主要参数(炉腔顶板高度、波导位置、耦合窗和转环滚轮高度等)。通过对主要参数的优化设计解决了M20L微波炉的打火、熔轴等问题,并提高了输出效率,进一步的实验研究证实该微波炉各项性能满足要求。 The typical M20L microwave oven was taken as representative and used computer simulation technology to study the match problems of cavity. Through the entity modeling of microwave oven and setting of electrical characteristics parameter of medium material in cavity, it studied and simulated M20L microwave oven. Results were in line with the actual test data, and verified the accuracy of model. On that basis, it researched the influence microwave oven cavity＇s structure parameters on the performance of the match, found the main parameters of influencing match are： height of cavity roof, position of waveguide, coupling window and roller height, etc. The optimization design of the main parameters solved the M20L microwave oven＇s problems such as striking fire and fusing shaft, also improved output efficiency, and further experiments or research confirmed that the microwave oven＇s various performance meet the requirements.
