本文提出了计算水平层状介质电阻率权系数的一种新方法,阐述了这种计算方法的原理,说明了这种方法的计算速度和精度。文中还给出了三层、四层介质权系数的一些计算结果,并简要分析了权系数的变化特征,特别是负效应和峰值增强效应。

This paper puts forward a new method for computation of resistivity weighting coefficients of horizontal strata. This method is the development of the digital linear filter method for the computation apparent resistivity curve for a horizontally stratified earth. The principle of the computation method is expounded. The computation speed and precision of the new method are illustrated. Some computation results of the weighting coefficients for a three and four horizontally layered earth are shown. The variation characteristics of the weighting coefficients are analysed with emphasis on negative effect and peaking effect.
