摘　　要：对混合液体组分的微波检测技术进行了研究。基于微波回波检测法,利用不同的物质具有不同的介电常数,将混合液介电常数的信息转变为微波特征参数的信息,通过矢量网络分析仪反映出来,从而快速精确检测出混合液各组分的含量。笔者选取回波法,即选取微波回波损耗作为特征参量,将混合液作为微波传输介质,通过微波探头直接测量出微波回波损耗,从而确定混合液组分含量。Detection of liquid components with microwave technology is studied in this study. Based on microwave pulse echo method, the information of permittivity can be turned into an argument of microwave due to different permittivity for different material, which can detect the liquid components rapidly and exactly. Microwave return loss （RL） can be directly determined with RL as an argument and the mixed liquid as microwave transmission medium. Thus liquid components can be determined by microwave pulse echo method.
