摘要
重磁界面的正反演方法研究是地球物理解释方法中的重要课题。本文在前人研究Raker反演方法的基础上采用了一种增强反演稳定性的快速正反演方法,并较好地解决了稳定因子中参数选择问题。本文还对该方法的收敛性及影响反演效果的诸因素加以详细讨论。理论模型及应用实例说明该方法是一种令人满意的快速正反演方法。
Abstract The study of the forward and inverse calculation of the gravity and magnetic
relief seems to be one of the important problems in the geophysical interpretaion method.Based on
Parker's inverse formula of gravity and magnetic fields, la new method for rapid,forward and
inverse calculation of the potential field anomalies is advanced in this paper, which can enhance
the stability in the inversion and solve the problem of selecting parameters in the stable factor.
In addition, the paper discusses improperly posed phenomena and other factors affecting the inve-
rse result. The results of both mode ng and field application are satisfactory.
