在磁法勘探资料的解释中，两度近似方法的重要性是人所共知的，特别是将它们与计算磁位的高次微商相结合的时候，更是这样。可是，在研究斜磁化物体磁异常的时候，我们见到，这些简单形体磁异常的表达式，不仅相当复杂，而且形式纷繁，这就给我们认识它们的共同特点，带来不少的麻烦。因此，提出了将磁异常公式规格化的任务。 The importance of the two approximation methods is well known in the interpretation of magnetic exploration data, especially when combined with high-order micro-quotients that calculate magnetic potentials. However, when we study the magnetic anomaly of oblique magnetized objects, we see that the expressions of these simple magnetic anomalies are not only complicated but also have many forms, which brings us a lot of troubles because we know their common characteristics. Therefore, the task of normalizing the magnetic anomaly formula is proposed.
