摘　　要：多年来很多学者开展了复电阻率电磁场正演模拟研究,然而大多数都是针对电性源进行的。鉴于此,这里采用体积分方程法进行了磁源激发条件下的复电阻率三维正演模拟。通过分析正演结果,得出了磁源激发极化法可行的结论,且磁场响应是由电磁感应和激电效应共同产生的,并引入磁荷概念总结了这两种效应的电磁响应规律。Over the years,many researchers have carried out complex resistivity forward modeling of electromagnetic fields,but most of the simulation are directed electrical source.For this reason,this paper use integral equation method,carrying out complex resistivity forward under the conditions of magnetic source modeling,forward by analyzing the results of magnetic source of induced polarization method obtained viable conclusion,indicating the magnetic field response is electromagnetic in-duction and the combined effect of the IP effect,and the introduction of magnetic charge summed up this view of the electro-magnetic responses of the two effects.
