在磁法勘探中,所谓的二度和似二度体,都是指沿走向水平的磁性体而言.但实际工作中所见的大多是沿走向倾斜的.有人曾提出过计算沿走向倾斜的磁性体异常的方法,但是与沿走向水平的情况相比,这类异常有什么特征,对这类异常如用常规方法作定量解释,给推断结果会带来什么影响,却很少论述.本文着重讨论这个问题. In magnetic exploration, the so-called second-degree and second-degree bodies refer to horizontal magnetic bodies, but most of what is seen in actual work is skewed along the course. Magnetic anomalies, but what are the characteristics of such anomalies compared with the horizontal ones? It is seldom discussed how these anomalies, such as the quantitative interpretation by conventional methods, have any effect on the inference results. This article focuses on this issue.
