对南海海洋重力资料运用矩阵法和二度的sinx/x法进行反演,所获得的莫霍界面深度比较合乎实际情况。文中进一步提出估算该区莫霍界面深度的经验公式,还对矩阵法和sinx/x法中起始点的选择及高频干扰等问题作了讨论。
Using the matrix method and the second-order sinx / x method to invert the gravity data of the South China Sea, the Moho interface depth obtained is more realistic. The empirical formula for estimating the Moho interface depth in this area is further proposed in this paper. The selection of starting points in the sinx / x method and the high frequency interference are also discussed.
