测定微波在波导中固定频率、匹配负载时的传导，通过改变膜片的特性，使形成的行驻波发生改变，在实验的基础上研究了影响行驻波比的因素。实验结果表明：影响驻波比的主要因素是膜片的反射率。
測定微波在波導中固定頻率、匹配負載時的傳導，通過改變膜片的特性，使形成的行駐波髮生改變，在實驗的基礎上研究瞭影響行駐波比的因素。實驗結果錶明：影響駐波比的主要因素是膜片的反射率。

The effect of diaphragm on standing-wave ratio was explored by changing the character-istic of the diaphragm to affect the formation of standing wave when investigating the microwave transmission in a waveguide .Factors affecting the standing-wave ratio were also studied on the basis of the experiment .The experimental results indicated that the main factor was the reflectivity of the diaphragm .
