摘    要：对于各种深度范围内的多层断面,可以用位于不同深度h_τ,纵向电导值为S_τ的导电薄层加以等效.S_τ,h_τ的表达式可以使用感应电压衰减曲线的微分值等参数换算得到.文中介绍了各种断面类型的S_τ曲线特征及解释方法,表明S_τ比ρ_τ参数对地层具有更高的探测能力.

Abstract: In this paper, the writer describes a method that makes the h_τ—depth and S_τ—conductance of a conductive layer, whose expressions can be attained by differentiating attenuate induced volt curves, equal to those in a multistratum section at variant depths. Also, the writer exhibits all sorts of variant sections' S_τ curves and their interpretive methods correspondently, thus, makes it known that the parametre S_τ has greater detectability to stratum than that of parametre ρ_τ.
