摘　　要：激电中梯法是我国金属矿电法勘探手段之一,被广泛应用于寻找金属矿产、解决水文地质和工程地质问题等。以中梯装置椭球异常体的激电异常理论为基础,针对野外地质体形态多样的特点,采用坐标旋转、椭圆积分等技术手段探讨水平大地均匀场中任意形态椭球体视极化率解析计算方法。IP intermediate Gradient is a major exploration means of electrical prospecting of metallic ore deposits in China,and be widely used in prospecting metal minerals and resolve the problems of hydrogeology and engineering geology.The paper is based on IP anomaly theory of the ellipsoid abnormal body in induced polarization ladder device,against the characteristics of geological body variety in the field,using coordinate rotation、elliptic integral and so on technologies to discuss the analytic calculating method of apparent polarizability and resistivity of ellipsoid in any form.
