偶极子法可用于防渗膜渗漏检测。膜上介质厚度以及偶极子与膜的距离会对偶极子检测的灵敏度产生影响。基于填埋场防渗膜高压直流电法的检测原理，对膜上介质厚度对偶极子检测的影响进行了研究，结果表明：防渗膜上介质厚度增大，通过在介质表面上移动偶极子来检测漏洞是困难的；但若偶极子能逼近膜的表面进行检测，无论膜上介质厚度多大，在漏洞附近都能检测到明显的电势异常。

Dipole method can be used to detect the leakage on the impermeable membrane. The thickness of the medium on the imper?meable membrane and the distance from the detection point to the membrane will influence the sensitivity of dipole detection. Based on the principle of high voltage DC leakage detection method, the authors analyzed the influence of medium's thickness on the detection. The results show that it is difficult to detect the leakage by moving the dipole on the medium surface when the thickness of the medium increases, but if the dipole can approximate the membrane, the dipole can detect the obvious potential abnormalities when it is approac?hing the leak.
