关于连续半空间的界面上具有直流点电源势的分布问题,是电法勘探的基本问题之一,若想求出一般的分析表达式是比较困难的,但想找到各种各样特殊情况下的解答仍然是可能的。 本文的目的,主要解答在单层介质中电导率按深度作σ=(σ_0+σ_1z)~αe~(βz)(α>0)变化时势的分布问题(这种情况不难推广到多层介质中去)。并结合实际构造了两类视电阻率函数。 从本文的结果上看,它既推广了[1]的结果对应部分,也推广了[2]的结果对应部分,尤其推广Sampaio,E.S.(1976)结果[4]中有关重要部分。
It is a basic problem of electrical prospecting that the distribution of power potential at DC point on the interface of continuous half space is one of the basic problems. If we want to find the general expression of analysis is more difficult, but want to find a variety of special circumstances The solution is still possible. The purpose of this paper is to answer the problem of the distribution of the electrical conductivity in a single-layer medium as a function of depth σ = (σ_0 + σ_1z) ~ αe ~ (βz) (α> 0) (which is not difficult to generalize to multilayer media In). Two types of apparent resistivity function are constructed according to the actual situation. From the results of this paper, it generalizes the corresponding part of [1] and the corresponding part of [2], especially the important part of Sampaio, E.S. (1976) [4].
