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. The total tendence show that deepened gradually from the east coast to west, Its change range is from 30km to 45km, and avrage depth is about 33.6km.

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。

The wave characteristics of Mawan Bay to Chiwan Bay is statistically analyzed based on the data from a wave station in Chiwan Bay. By using the 15-30 year wind data from the Chiwan Bay and nearby stations, both the National Harbour Hydrology Standard method and the Ippen method are applied to predict the maximal water wave in Mawan Bay. The conclusions are as follows:1. The general wind direction is E-SE in the study area. The strong wind direction is SE or SW-NNW. Due to the restriction of topography, the water wave in this area is wind-wave dominative and not very strong. Annual average wave height is 0.2m. The maximal wave height observed is 1.92m with period of 4.6s.2. Typhoon is the only major factor generating the maximal wave in Mawan Bay. About 1.4 typhoons every year arrive the Pearl River Estuary and affect this area.By introducing the concepts of short fetch and equivalent fetch, the probability of maximal wave is forcasted with the wind directions respectively in S, SW,W, NW, and NNW.The probability of height and period of maximal wind wave in every 100, 50, 20, 10, 5 , and 2 years are obtained by using the standard method and the Ippen method.Both yield concordant results. Using the standard method, the maximal wind wave height in every 50 years is 2.0-3.5m with period of 5.0 -6.7s. This result is comparable to that obtained for Chiwan Bay and may be used as reference data for harbour constructions in Mawan Bay.
