摘要

本文介绍了一种基于频域反射法(FDR)的探针法测定膨润土的湿度和介电常数。本研究中使用的探针的基本原理是在100 MHz下测量土壤的折射率√ε，从而通过这些量之间的已知关系来确定湿度。本研究得到的相关系数为0.99，表明湿度与膨润土介电常数之间存在较为准确的关系。本研究还比较了FDR法所得膨润土的湿度与电石法所得的湿度。

Frequency domain reflectometry in the determination of dielectric constant of bentonite

This work presents the determination of the humidity and the dielectric constant of bentonite using a probe based on the frequency domain reflectometry (FDR) method. The basic principle of the probe used in this study is the measurement of the refractive index of the soil √ε at 100 MHz to allow the determination of the humidity through a known relation between these quantities. The value of 0.99 for the correlation coefficient obtained in this study demonstrated an accurate relationship between the humidity and the dielectric constant of bentonite. Also in this study the humidity of the bentonite using the FDR method was compared to the values obtained using the calcium carbide method.
