摘　　要：在连续阵列大地电磁(CEMAP)时间域电场空间拓扑理论研究的基础上,提出了使用单频点多极距ρXY曲线来表现地表横向电性不均匀体所产生的静态效应的思路,在同一观测系统中以人机联作的方式正演计算不均匀体所产生多极距静电压曲线,并用其压制实测多极距ρXY曲线上由静态效应引起的形态起伏,以实现静态校正。开发的拓扑去静态软件,在对实测数据处理的过程中取得显著效果。Based on the electric field topological theory of continuous electromagnetic array profiling(CEMAP)method,the static migration can be showed on multi-electrode distanceρXY profile curves.The multi-electrode distance profile curves of static voltages induced by near surface conductivity inhomogeneous bodies can be put forward in the same observation system by using man-machine interactive method.The shape of voltage curves can correct the static migration on theρXYcurves.The topological static correction software developed by us achieved remarkable result in processing measured data.
