图2 基于模型一开展等效源等效性分析的结果 a—等效源位置与实际情况一致时的计算结果;b—上移1 m等效源的计算结果;a1、b1—与原始数据的拟合差;a2、b2—下延5 m误差;a3、b3—上延5 m误差;a4、b4—反演重构的等效源

Fig.2 Results of equivalent source equivalence analysis based on model 1 a—the calculation result when the equivalent source position is consistent with the actual situation; b—calculation result of moving up 1 m equivalent source; a1, b1—poor fitting of raw data; a2, b2—downward 5 m error; a3, b3—upward 5 m error; a4, b4—equivalent sources for inversion reconstruction
