高精度重力勘探的测量精度已从毫伽级提高到微伽级。
The measurement precision of the high accuracy gravitation exploration technology has been increased from rank of milligal to microgal.
在JX地区，由莫氏界面的起伏只能引起21—42毫伽的重力异常值。
The undulation of Mohorovicic discontinuity under JX region only causes the gravity anomaly of 21-42 milligals.
理论计算表明其影响值可达10毫伽左右，与观测的重力异常值大致相当。
Theoretical calculations show that the influence value can reach 10 milligals or so, and matches fairly well with the observed gravity anomaly value.
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。
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.
