摘　　要：用等效磁源法实现常规磁异常换算(延拓、求导、假重力异常换算、化磁极)的模型计算算例显示了等效源法在使用上的灵活性和方便性。与频率域换算方法相比,说明了等效源法换算结果更优于频率域换算结果。Theoretical examples of magnetic anomaly conversion (continuation, derivation, pseudo-gravity and reduced to the pole) with an equivalent source method are given in this paper. The flexibility and simplifying of the method are shown in application to the synthetic modeling and the results are better comparing with frequency domain method.

关 键 词：等效磁源法 磁异常转换 换算 多解性
