| 摘 要： | 土壤作为一种介质，其介电常数的测定是其含水量测定的基础，介电常数不仅与它的机械组成和化学成分有关，而且还与它的电阻率有关，由于土壤是层粒结构，分布电容的影响使其电阻率的测定有一定难度，本文根据土壤的机构组成，运用电磁理论对土壤在直流电压下的极化过程进行了分析，为它的含水量的测定找到了理论依据。

| Abstract: | As soil is a medium, the measurement of its dielectric constant is the basis of determining the moisture content in soil The dielectric constant has something to do with the mechanical and chemical composition as well as resistivity Since soil is a kind of layer and particle structure, the measurement of its resistance has some difficulties due to the effect of distributive electric capacity On the basis of soil composition and theories of electromagnetic wave, this article analyzed the procedures of soil polarization under direct current at certain voltage and thus it provides a theoretical foundation for determining the moisture content in soil |
