Using the Principle of Coordinate Transform to Solve Potential Problems Distribution of Multi Geo-Electric Bodies

利用坐标平移、旋转、和不同坐标系统之间的转换,本文研究多个大小不同、形状各异、电性不匀的地电体共存于均匀电流场中的电位分布问题,提出了求解这类复杂电性分布的技术思路和方法,给出了在忽略地电体相互影响的条件下,多个地电体共存时电位分布的理论公式和计算方法,探讨了地电体之间影响可以忽略的具体条件。对解决复杂地电分布的正演问题作了有益的探索。

Use of coordinate translation,rotation,and conversion between different coordinate systems,the electric potential distribution problem of multiple geo- electric bodies which have different sizes,different shapes and different electric resistivity coexisting in an uniform current field are studied in this paper. Technology thought and method to solve this kind of complex electric resistivity distribution are put forward. Theory formulas and calculation methods are presented in the condition that the influences between different geo- electric bodies could be ignored. The actual conditions that the influences between different geo- electric bodies can be ignored are discussed. To solve the forward problem of complex ground electric resistivity distribution is helpfully explored.
