变化电性剖面法应用特例介绍

AN INTRODUCTION OF A PROFILE IN VARIATION ELECTRIC PROPERTY

在地电阻率观测中,由于表层变化影响往往使地电阻率测值产生一些不规则的非随机变化。本文以“变化电性剖面模型”为基础,计算出正常背景值,以消除表层变化的影响。实例计算表明,这一方法用来消除高阻型台站上所特有的幅度大而不规则的似年周期变化,较之一般的纯数学方法处理资料有利。

The observed value of earth resistivity is caused to produce some irregular unstoehastic variation by the influence of surface variation. In this paper, basing on the profile model of variable electric property, the normal background value is calculated to eliminate the influence of surface variation. The result shows this method is better to handle data than the general mathematics do to clear up pseudo annual period variation of large in range and irregula in model which exist in the high impendance stations.
