摘　　要：根据三极和对称四极直流电阻率测深的转换函数曲线性质,用大地电磁测深中BOSTICK相同的方法,导出了对电阻率转换函数曲线的直接反演公式。经过对6个模型的电阻率转换函数曲线进行反演检验,该公式虽能近似反映地电断面情况,但误差较大。本文对视电阻率测深曲线的直接反演公式进行改进,得到了另外两种精度较好的直接反演公式。同时给出了对一些例子。According to the natures of the transform function in vertical electric sounding, this paper derives a direct inversion method for transform function curve by means of the same method as BOSTICK in magnetotelluric sounding. To improve the inversion precision,we combine this method with the direct inversion method for electric sounding curve and get another two inversion methods for transform function curve. Some examples are given in this paper.
