摘　　要：介绍不接触电极电法测量的基本原理,分析视电阻率测量与视阻抗探测方法,进行视电阻率模型试验;提出视阻抗测量的理论模型,并进行了金属和非金属异常体模型试验,验证了视阻抗测量方法的正确性,可以适用于不同环境探测,区分介质的导电性差异和介电性差异,为工程探测提供一种快速、方便、准确的多参数检测手段。The principle of non-contact electrode measurement is introduced. Apparent resistivity measurement and apparent impedance measurement are analyzed. The apparent resistivity mode experiment is made. The theoretical model of apparent impedance measurement is presented. The metal abnormity and nonmetal abnormity model experiments were made, which proves the correctness of apparent impedance measurement and non-contact electrode measurement is available under different environment and differentiates the diversity of electric and dielectric property of medium, offering a convenient precise quick method of multi parameter detection for engineering exploration.
