摘要
基于偶极—偶极电极装置的瞬变响应表达式，建立了双极源电场的等效偶极和三次插值的快速近似算法。通过在一些典型地电断面上对算法的试算，表明三次插值法是一种较稳定的快速算法，从而实现了时间谱电阻率法一维正演的快速计算。
This paper deals with the algorithms of equivalent dipole approximation and cubic interpolation for the electric field component of ground electrical bipole source.The calculations for some typical geoelectric sections are performed to test the established algorithms.The results show that cubic interpolation algorithm is preferable to equivalent dipole algorithm while carrying out the one dimensional forward calculation for time spectral resistivity (TSR) method.
