摘要
本文主要介绍微波腔体传感器用于工农业生产过程中对物质的湿度、温度、厚度和材料的电磁参数测量的基本原理,综述半个世纪以来,微波测量湿度、温度、厚度以及材料电磁特性等的应用概况.
This paper expounds the basic principle of measurements of the moisture, the temperature, the thickness and the material electromagnetic parameters about the microwave cavity sensor's application lies in the production of the industry and the agriculture. Summarizes of the microwave measurements the moisture, the temperature, the thickness and the material electromagnitic properties expounds application in the guasi century.
