本文从物理概念的分析出发,用等效电路方法,简捷地推导出顶点电位公式。从而使多层角域视电阻率曲线的极值点数据能正确地计算出来。此外,在已知电阻率的两层介质接触情况下,还可能根据接触线上供电时实测的视电阻率值来估计接触面的倾角。
Starting from the analysis of the physical concept, this paper deduces the formula of the vertex potential simply by using the equivalent circuit method. So that the multi-layer angular dependence of the apparent resistivity curve data can be calculated correctly. In addition, it is also possible to estimate the contact angle of inclination based on the measured apparent resistivity at the time of contact line power supply in the case of two-layer medium contact with known resistivity.
