本刊编辑部备有点源二维有限单元法、有限差分法和点源三维积分方程法的Fortran语言程序及BD—200语言程序各一套。这些程序适用于复杂地电断面的正演计算,也可用于反演计算。有限单元法程序还适用于计算复杂地形条件下、任意剖面(包括主剖面和旁侧剖面)的各种装置的视电阻率和视极化率值。该程序具有功能强,操作简便等特点。其计算精度和速度都超过了国外同类型程序的水平,并于1982年由地矿部物化探局评审通过。凡需要该程序以及咨询的用户,请来函向成都地质学院内《物化探计算技术》编辑部联系。
Our editorial department is equipped with point source two-dimensional finite element method, finite difference method and point source three-dimensional integral equation method Fortran language program and BD-200 language program each one. These procedures are applicable to the forward calculation of complex geoelectric sections and also to inversion calculations. The finite element method procedure also applies to the calculation of apparent resistivities and apparent polarizability values for various devices of arbitrary section (including main section and side section) under complex terrain conditions. The program has strong features, easy operation and so on. Its calculation accuracy and speed are beyond the level of the same type of procedures abroad, and in 1982 by the Geological Exploration Bureau of Geology and Mineral Resources Bureau approved. All users who need this program and consultation, please write to the editorial department of “Geophysical and Geochemical Calculation Technology” in Chengdu Institute of Geology.
