二维磁异常和三维磁异常之间的关系是磁法解释中一个令人感兴趣的问题。由于与二维异常有关的参数少，因此它的解释方法比三维异常简便，解释方法也很多；而三维异常的解释，除了象球体异常这样的特例之外，现有的简便方法是不多的。这样，一种很自然的想法是：能否把三维异常转化为二维异常来进 The relationship between two-dimensional magnetic anomalies and three-dimensional magnetic anomalies is a matter of interest in magnetic interpretation. Due to the small number of parameters related to two-dimensional anomalies, its method of interpretation is exceptionally simple and unusual than three-dimensional, and there are many explanations. However, the explanation of three-dimensional anomalies is few except for special cases like spherical anomalies . In this way, a very natural idea is: whether the three-dimensional anomalies into two-dimensional anomalies to enter
