    The Moho depth calculated by inversing the gravity data of South China Sea region by means of matrix and 2-D sinx/x methods conforms better with actual data. The empirical formula used to estimate the Moho depth under South China Sea is presented in this paper. The selection of initial point in employing the matrix and sinx/x methods is approaced, and high frequency noises are also analysed in the paper.

    In this paper, the deep gravity anomalies obtained through field potential transformation from the Bouguer anomaly data, in Anninghe area are inversed to get the Moho depth, by method of the Compressed Mass Plane. Characteristies of the deep structure in the area have been studied, and the deep faults have been qualitatively confined by vertical second derivative of gravity. The tentative study of the relation between deep structure and earthquakes has also been carried out in the paper. The results are. ( 1 ) Since the area is located in the joined area of Qingzang block and South China block, features of the deep structure have also shown such a complexity of the joined area; ( 2 ) The deep crust is severely constrained by approximately E-W tending structure, while the south segment of the N-S tending Anninghe fault at Xichang has not shown on the deep structure; ( 3 ) The area of strong seismic activities has close relation with the deep structure. The Xichang-Mianning segment, located at a specially structural area, is still the very segment for repetition of strong earthquakes in the future.

    Based on the recording data of head wave of 164 observed points from five artificial explosions in central and east area of China, the Moho discontinuity is studied with time term method after correction of the travel-time for elevation in this paper.In order for save of memory capacity in electronic computer, increment of velocity and calculation accuracy, and convenience of calculation in small-sized computer, the velocity V_(pn)=8.005±0.028km/sec. of head wave along the Moho discontinuity and time terms a_i at 164 observed points are found using the methods of the characteristic number group T(i, j) made from the specified regularity and partitioned matrices to inverse.Taking average wave velocity V_0=6.25km/sec of the overlying medium over moho surface, the moho depth at each point is obtained by reversion based on the data of reflection wave on Moho discontinuity, and Moho outline figure with isobathy lines inthis area is mapped.It will be seen from this figure that depths of Moho discontinuty increase in the Dabeishan region and the region to the of NS- gravity gradient zone in EastChina, which reach 36km and 45km respectively, but that of Moho surface become shallow in basins and/or great lakes and plain, which is 30km generally.

    本文根据华中、华东地区5次人工爆破时164个观测点上的首波P_n的记录资料,对P_n走时经过高程校正后采用时间项法研究该地区莫霍界面的形态。 为了节省计算机内存,提高计算速度和精度,便于在小型机上计算。本文采用了按一定规则形成的特征量数组T(i,j)和矩阵分块求逆的方法。计算得到英霍界面首波的速度v_(pn)=8.005±0.028公里/秒以及164个观测点的时间项a_i。根据本地区M—面反射波的结果。取M—面上覆介质的平均波速v_0=6.25公里/秒。反演得到各点的莫霍界面深度,并且给出该地区莫霍界面等深线轮廓图。由该图可见,区内大别山和我国南北重力梯级带以西,M—面显著变深,分别达到36公里和45公里;而盆地和大湖区,M—面变浅,一般为30公里深。莫霍界面变化的总趋势是,从东部沿海往西逐步加深,变化范围为30—45公里,平均深度为33.6公里。
