摘    要：本文讨论了在均匀半空间中带有浸染球壳的球体上中间梯度装置异常的特点。分析了浸染球壳的电性参数(电阻率、极化率)和几何参数(球体中心埋深、浸染球壳的厚度)对中心剖面上激电异常特点的影响。得出了一些基本结论:球壳增加了勘探深度;当利用视极化率曲线或视电阻率曲线求球体中心埋深时,不会引入误差

Abstract: In this paper characteristics of the IP anomaly of a spheroid Surroundedby impregnate spherical shells in homogeneous half-space along the gradie-nt array are discussed.The effect of electrical parameters(resistivity,IPsusceptibility)and gemetric parameters(the huried depth of the spheroidcenter,the thickness of impregnate spherical shells)on characteristics ofthe IP anomaly along the central profile is analysed.Then some essentialconclusions have been abtained.The presence of impregnate spherical she-lls causes an increase in the penetrate depth.And it does not bring errorsto determine the depth of the spheroid center by usingcurves of apparentresistivity or IP.
