摘要
基于层状导电和可极化大地表面,电偶源电场水平分量Ex(t)和磁场垂直分量时间导数瞬变响应的计算结果,分析和概括了阶跃响应随电磁(EM)和激电(IP)效应的变化规律。并在此基础上,初步探讨和肯定了建立时间谱电阻率法的可能性。
The transient responses of Ex(t), the horizontal component of the electric field produced by an electric current dipole with a down step waveform, and the partial derivative of the vertical component of its magnetic field with respect to time,are calculated for the stratified collductive and polarizable earth surface.Variations of transient responses for both Ex(t) and are discussed and summarized. Accordingly, the feasibility of time spectral resistivity(TSR) method is initially probed and affirmed.
