摘　　要：利用模拟电荷法对椭球体的电阻率曲线进行了数值计算,介绍了模拟电荷法的原理,匹配点及模拟电荷的设置方法,并编程计算了椭球体的电阻率曲线。椭球体是典型的三维地电体,实现椭球体电阻率的数值模拟,就可以计算绝大多数三维地电体的电阻率曲线,为深入研究电法勘探技术提供理论依据。In order to solve numerical calculation straightforward problem of electrical prospecting, this article calculates the apparent resistivity curve of ellipsoid by applying the simulate charge method. The author introduces the theory of the simulate charge method, the arrangement of contour point and design of simulating charges, and also developed the cor- responding program. The ellipsoid is typical 3-dimensional geo-electrical body, it can calculate most of the apparent resis- tivity curves of 3-dimensional geo-electrical body after calculating the apparent resistivity curve of ellipsoid, The results can provide a preliminary premise for researching electrical prospecting.
