摘要

本文提出了双界面模型重力场正演时级数求和的快速收敛方法和反演时保证反演问题稳定快速收敛的具体措施.这些方法和措施不但可用于密度界面的正反演,而且也可用于简单或复杂形体的正反演.通过模型试算和实际资料处理均取得了很好的效果.

Abstract

In this Paper, the method that ensures fast convergence for the summing of scried in forward problem is dcvclopcs and some specific measures that ensure stable and rapid convergence for invcsc problem arc studied for a gravity model with dual interfaces. They can be used in both density interface cases and simple /complicated geological body cases. Good processing results have been achieved on field data.
