微重力与微重力梯度异常的广义逆综合反演

THE METHOD OF COMPREHENSIVE INVERSION FOR MICRO GRAVITY AND GRAVITY GRADIENT ANOMALIES BY GENERALIZED INVERSE MATRIX

将微重力异常与微重力梯度异常同时代入广义逆反演过程中，不需进行人为约束，在微重力异常和微重力梯度异常分别得到拟合的前提下，自动地综合修改模型参数，不仅其反演结果的多解性大大减少，而且其收敛速度比单一异常反演的收敛速度快；此外，综合反演还能使短剖面的异常对复杂地质体的反演成为可能。广义逆综合反演的基本原理可推广应用到其它地球物理方法中去。

The ambiguities in gravity inversion is reduced when the gravity and gradient anomalies are put into inversion in combination. The parameters are modified automatically as the gravity and gradient anomalies are being simultaneously imitated.And comprehensive inversion converges more quickly than single anomaly inversion does.It is possible that anomalies of short seetion can be inversed for bodies of complex shape. The principle is also valid for other geophysical methods.
