residual gravity anomaly

基本解释

In dealing with the gravity data of some basin, obtain the residual gravity anomaly applying finite element method.
在某盆地的重力资料处理中，用有限元插值法分离出该区的局部重力异常。
The residual gravity anomaly was mainly produced by rolling basement of the basin and the regional gravity anomaly by the Moho rolling.
推断引起剩余重力异常的主要原因是盆地基底的起伏，引起区域重力异常的主要原因是莫霍面起伏。
However, there occurs 5-70 milligals gravity anomaly in this region, the residual anomaly being 30-50 milligals after eliminating the effect of Mohorovicic discontinuity.
然而，在此区却出现了5—70毫伽的重力异常值，从中去除莫氏界面的影响，其剩余异常值还有30—50毫伽。
