The application of three-dimensional inversion of gravity and magnetic fields are very important not only in geophysical researches, but also in the study of geological structures. A formula of potential field in frequency-domain, developed by Parker in 1973, can be used as a rapid and effective algorithm in gravity and magnetic inversion. The technique has been improved then by Oldenburg, Sprenke, Feng and others.

Parker位场公式可做为一种十分快速的算法用于重磁反演计算中。本文给出了有关的正反演公式及其应用范围,并从程序设计的角度做了具体讨论。在单界面反演中采取了平移下界面和递推界面修正量的措施,分析了压低边界效应和低通滤波技术;文中指出密度与界面的变化对重力谱的影响存在着二阶差异,据此在对密度和界面同时反演时,可采用交替加权迭代的办法,并给出了相应的权因子;相似的处理技术也可以用于对多界面的同时反演。针对解的非唯一性,讨论了引用地震测深资料进行约束的途径。
