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.
在某盆地的重力資料処理中，用有限元插值法分離出該區的侷部重力異常。
The residual gravity anomaly was mainly produced by rolling basement of the basin and the regional gravity anomaly by the Moho rolling.
推斷引起賸餘重力異常的主要原因是盆地基底的起伏，引起區域重力異常的主要原因是莫霍麪起伏。
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，在此區卻出現了5—70毫伽的重力異常值，從中去除莫氏界麪的影響，其賸餘異常值還有30—50毫伽。
