摘　　要：通过偶层场强分量表达式作为第一类Fredholm积分方程,求解虚拟磁偶极子的层磁化强度J(α,β)。再将求得的磁化强度J(α,β)代入偶层场强分量表达式算出矩形网格节点上的位势值。它实现了保留位势数据物理特性的散乱位势数据网格化。In this paper, the solution of magnetization intensity J (α,β)on imaginary magnetic dipole layer was obtained by the represantation of dipole layer field density component which was regarded as the first kind Fredholm intergral equation and the potential data on the rectangle grid point was computed by the solutionJ(α,β)which was taken into the represantation. It realizes gridding the scattered potential data which keep the physical character of potential data.
