正反演是重磁解释中很重要的一个步骤,过去这部分工作都是在空间域中进行的,如各种规则形体的正演公式,点元线元或面元的正演程序,最优化选择法(如马奎特方法)反演程序等,这些在实际工作已取得一定效果。近一年来,频率域位场转换工作已在数据处理中广为利用,同时,频率域正反演工作也在逐步开展,如组合斜顶面棱柱体正演程序,功率谱计算基底深度程序等已在开始使用,此外对频率域其他反演方法也在研究与试用。考虑
Forward and inverse inversion is a very important step in the interpretation of gravity and magnetic field. In the past, this part of the work was carried out in the space domain, such as the forward formula of various regular forms, forward program of point-element line element or element Optimization selection method (such as Marquardt method) inversion procedures, which have achieved some results in the actual work. In the past year, the field work of frequency domain conversion has been widely used in data processing. In the meantime, the work of forward and inversion in the frequency domain has also been carried out gradually. For example, the combination of oblique top prism forward program and power spectrum calculation base depth program Already in use, in addition to other inversion methods in the frequency domain are also being researched and tested. consider
