摘要
根据无限延深直立厚板和有限延深直立厚板的磁异常公式 ,求出磁异常的不定积分变换结果 ,并根据变换结果绘制磁异常变换参量图。在取不同空间几何参数条件下 ,讨论各变换参量图的变化规律 ,寻找由深度和厚度引起变换磁异常变化最显著的方向 ,以及与异常变换前参量图进行特性对比和效果分析。同时讨论了目标体埋深很大时有限延深直立厚板与水平圆柱体的变换参量图的相似性。该方法可简易、快速地区分异常体形状 ,能突出一些为常规处理所淹没的重要地质信息 。
From the two kinds of magnetism abnormality formulae, we deduce respective results of indefinite integral transformation, and plot a series of parameter figures for them. According to the varieties of different spatial geometrical parameters, the variation of these parameter figures is discussed. We seek the most obvious direction in which the spatial geometrieal parameter affects the abnormalities most and conclude a series of regulations toward various object modes. At the same time, we discuss the similarity between the parameter figures of a limited erect thick plank and a horizontal cylinder when the object is deeply buried. The magnetisms can be distinguished by this method easily and quickly. This method can abstract plenty of important geological information, and contribute to the explanation of magnetic exploration .
