一、引言在已推广的电测深曲线反演解释程序中,按拟合对象可分为拟合核函数(即T函数)及拟合视电阻率函数(即ρ_s函数)两种。各具有不同的特点和长处,对它们的看法和认识也不一样。在地质部水文地质工程地质技术方法研究大队唐大荣和张文良同志编写的《直流电测深曲线计算机解释原理及方法》(1979年10月24日初稿)一书中谈到:拟合T函数的方法速度快但精度低,而拟合ρ_s函数的方法正好相反,速度慢但精度高。书中分析了造成拟合T函数方法解释精度不高的两个原因:1.T曲线的分辨能力不如ρ_s曲线高,拟合
I. INTRODUCTION In the extended interpretation procedure of electric sounding curve, the fitted objects can be divided into two types: fitted kernel function (ie, T function) and fitted apparent resistivity function (ie, ρ_s function). Each has its own distinct characteristics and strengths, and its perceptions and perceptions are different. In the book “Theory and Method of DC Interpretation Curve Computer Interpretation” (draft of October 24, 1979) written by Comrade Tang Dayong and Zhang Wenliang, a research team of hydrogeology and engineering geology methods of the Ministry of Geology, we talk about the method of fitting T functions Fast but low-precision, but the method of fitting ρ_s function is just the opposite, slow but high precision. The book analyzes two reasons for the interpretation of the fitted T-function method to explain the accuracy is not high: 1.T curve resolution ability than ρ_s curve high, fitting
