摘要
提出了一种通过利用微波方法测量物质复介电常数来分析土水系统特性的方法,并设计了一种环保传感器.该传感器采用较简单的单端微波反射系数法,并利用多孔陶瓷材料制成渗透室.本文论述了此种传感器的设计、制造以及实现测量的方法.
A new method was proposed to analyze the character of a soil-water system by measuring the complex permittivity with high-frequency microwave, and an environmental protecting sensor was designed. In the design, the single-ended reflex coefficient method was used and porous ceramics was made into the permeation cell. This paper described the design, production and date processing technique.
