【Abstract】 The forward solution of the electrical field due to a point source in layered media is used to either ground or underground electrical exploration for vertical or horizontal multilayered media.The recarrence formulas are derived which are used to calculate the undefined coefficients in the integral expressions for the electrical potential. The numerical integration of electrical potential can be carry out by means of Gauss-Laguerre formula. The programs designed can be used to fast calculate the apparent resistivity for any electrode configuration,any number of medium layers and arbitrary oricntation of electrode (normal to, oblique to and parallel with the interface strike).更多还原
