摘要
作者通过均匀电场中的实测发现,虽然有限面极化体其界面的极化系数频谱特性可满足柯尔模型,但该模型的参数是界面位置的函数.本文建立了面极化柱(球)体面极化系数的一般表达式.通过理论计算,出现了复电阻率异常曲线的宽度和形态随频率发生奇异的变化,该理论结果得到实验的证实.有限面极化体复电阻率异常的这种奇异性,乃是激电效应为“准”线性系统的基本属性.
By measurements in a uniform electric field, it has been found that the frequency spectrum of surface polarization coefficient on the interface of a finite surface polarizable body can satisfy thecole-cole model with its parameters as a function of the location of the interface. A general expression of surface polarization coefficient for a surface polarizable cylinder (or sphere) was established.It is shown by calculation with the expression that a curious variation of the width and shape of complex resistivity anomaly curves will be obtained. This result has been confirmed by experiments.This curious feature of complex resistivity anomaly is believed to be a basic attribute of the'quasilinear'IP effect.
