摘　　要：通过对等效导电平面方法原理的阐述,指出了利用视纵向电导参数进行瞬变电磁测深资料解释的优越性。为了提高对电性层位的分辨能力,实现了电导参数的微分成像校正技术。实践证明,采用该方法的成像结果与其他反演结果吻合较好,其"电性同相轴"以直观、形象的面貌清晰地展示了电性界面的分布形态。Through the elaboration of an equivalent conductive plane principle, the advanta- ges of the use of apparent vertical conductance parameters to interpretate transient electro- magnetic sounding data are pointed out. In order to improve the resolution ability of electri- cal layer, the differential conductance imaging parameters correction is achieved. The ima- ging results achieved by this method agree with other inversion results, whose electrical phase axis shows directly and clearly the distributions of electrical interface.
