磁测反演计算大多建立在水平面上,在地形起伏、切割剧烈、高差较大的山区开展磁测工作,严重的地形影响,给磁异常的推断解释带来困难.因此,研究消除地形影响的方法早已为人们所重视,复变函数保角映射的应用,使这一问题(二度体情况)基本上从理论到实际得到了解决.对于某些特殊地形(抛物线、单斜面、阶地等)可采用一些解析函数进行座标变换,达到地改目的,但这些特殊地形在野外是不多见的,实用意义也是不大的.由于导电纸的引用,可以利用“座标网模拟转换法”解决任意起伏地形的磁测地形改正(二度体情况),这是便于野外推广而行之有效的方法.目前所推
Most of the magnetic inversion calculation is based on the horizontal plane, so it is difficult to carry out magnetic surveying in mountainous areas where the terrain fluctuates sharply and the height difference is relatively large, and the terrain effects are serious and the interpretation of magnetic anomalies is difficult.Therefore, Has been paid attention to by people, and the application of the conformal mapping of complex functions makes the problem basically solved theoretically and practically. For some special terrain (parabola, monoclinic, terrace, etc.) ) Some analytic functions can be used to coordinate transformation, to achieve the purpose of the reform, but these special terrain is rare in the wild, practical significance is not large. As the reference of conductive paper, you can use “coordinate network analog conversion Law ”to solve any undulating terrain of magnetic topographic correction (second body conditions), which is easy to promote the field and effective method.
