前言重磁异常的正演计算以往大多在空间域进行,所用模型的计算公式都比较复杂,计算速度慢,特别是三维情况更是如此.近年来,这种正演计算为普遍地改在频率域进行,计算速度变快,但由于在频谱数字化过程中存在的一些问题,使计算精度受到一定的影响. 我们根据文献中所提供的矩形棱柱体磁 Foreword The forward calculation of gravity and magnetic anomalies mostly in the past in the space domain, the calculation of the model used are more complex, slow calculation, especially in the three-dimensional situation is even more so.In recent years, this forward calculation is generally changed to the frequency Domain, the calculation speed becomes faster, but due to some problems existing in the process of spectrum digitization, the calculation accuracy is affected to a certain extent.According to the literature provided by the rectangular prism magnetic
