目前在磁法勘探的书籍和文献中,当讨论到磁性体的磁场时,常假设地形是水平的;而地面磁测常在山区进行,所得磁异常往往是沿地形起伏线分布的。为了解释起伏地形上的磁异常,有两种办法:一是将地形线化直,将起伏地形上的磁异常转换为水平线上的磁异常,而后作解释;另一种办法是在起伏地形上直接作解释。以前提出的直接 Currently in the magnetic exploration of books and literature, when discussing the magnetic field of magnetic body, it is often assumed that the terrain is horizontal; while the ground magnetism is usually carried out in the mountainous area, the magnetic anomalies are often distributed along the relief lines. In order to explain the magnetic anomalies on the undulating terrain, there are two ways: First, the terrain straightening, the undulating topography of magnetic anomalies on the horizon into a magnetic anomaly, and then to explain; the other way is in undulating terrain Directly explained.
