摘　　要：针对垂直层状结构岩层的电阻率分布特征问题,采用直立多层介质地面电场递推公式,计算岩层为多个垂直接触面时的地面视电阻率。利用Hankel线性滤波对零至无穷大区间的积分进行数值计算,使用多种电阻率测量装置进行正演计算,得出垂直接触带上多种测量装置的理论视电阻率异常特征。The ground resistivity of the stratum is calculated by using the recursive formula of the ground electric field of the upright multi-layer medium.The Hankel linear filtering is used to numerically calculate the integral of zero to infinity intervals.A variety of resistivity measurement devices were used for forward calculation to obtain the vertical contact with a variety of measuring devices on the theoretical characteristics of abnormal resistivity.
