为研究非饱和铜污染砂的交流电阻率特性，用数字电桥测试了不同铜离子含量、不同含水量、不同孔隙率的砂在不同电流频率下的交流电阻抗并换算成电阻率，绘出电阻率与这些变量之间的关系曲线予以分析。结果表明：非饱和铜污染砂的电阻率随电流频率、铜离子含量、含水量的增加而减小，随孔隙率的增加而增加。

In order to study the AC electrical resistivity properties of unsaturated sand polluted by copper, the AC impedance of different contents of copper ion and water, and different porosities un-der different current frequencies was measured and turned into AC electrical resistivity. Curves that indicate the relation between each variable and the electrical resistivity were drawn and analyzed. The results show that the electrical resistivity decreases with the increase of electrical current fre-quency, copper ion concent and water content, whereas it increases with the increase of porosity.
