等电位綫法是苏联專家系統地介紹到我國的地球物理勘探主要方法之一,它可广泛地应用於良導电性的硫化金屬礦床上的普查找礦工作中。在我國使用的短短時期中,就表現了它是一种找尋良導电性的金屬礦床最有效而生產率最高的方法。等电位綫法分直流电等电位綫法及交流电等电位綫法兩种。按苏联幾十年的工作經驗証明:直流电等电位綫法的结果最好,可避免較高頻率的交流电等电位綫法的感应現象所引起的电埸歪曲,並且勘探深度也較深。
The equipotential line method is one of the main methods of geophysical prospecting systematically introduced by the Soviet experts into our country. It can be widely used in the census and prospecting work on sulphide-bearing metal deposits with good conductivity. In the short period of its use in our country, it has shown that it is the most efficient and productive method of finding good conductivity metallogenic deposits. Equipotential line method is divided into direct current equipotential line method and alternating current equipotential line method two kinds. According to decades of work experience in the Soviet Union, it has been proved that the result of DC equipotential line method is the best, which can avoid the distortions caused by the induction phenomenon caused by the high frequency alternating current equipotential line method and the deep exploration depth.
