The circulation in bohai sea and yellow sea is basically of cyclone shape comprising the coastal currents and the yellow sea warm current . besides the real circulation simulation , numerical experiments were done to study the dynamic mechanism 另外，在真实环流模拟的基础上，本文又进行了一些数值实验，以考察各动力因子对冬季东中国海环流的影响。
Model results showed that tidal currents over the shelf from the continental edge to the entrance of the yellow sea rotated in a clockwise direction , while the currents in the yellow sea were rectilinear following and their direction of propagation along the coast 论文系统分析了东中国海四大分潮的潮汐和潮流特征，潮流模拟结果表明，东海陆架边缘到黄海，潮流基本呈顺时针方向旋转。而在黄海，其潮流基本呈往复流特征。
In a surprisingly short time , a wide range of topics has come up : economic and environmental co - operation ; mechanisms to ease territorial disputes in the east china sea , complicated by possibly large deposits of gas and oil ; even confidence - building measures between the two countries ' armed forces 在近期，一些话题迅速升温，经济和环保合作；由于东海存在大量天然气和石油，双方展开东中国海领土争端的谈判；甚至两国军方也开始建立互信。
A three - dimension baroclinic prognostic model on the o - coordinate is established based on pom to simulate the wintertime circulation and the eddies in the east china seas , considering the topography , inflow and outflow on the open boundary , yangtse runoff , heat flux and wind stress on the sea surface 本文在pom模式基础上，建立一个坐标系下的三维斜压预报模式，考虑了海底地形、外来流、长江径流、海面风应力、海面热通量等多方面因素的影响，模拟结果较好地体现了冬季东中国海环流及涡旋的特征。
This dissertation studies the inversion of sound speed profile ( ssp ) in shallow water , including the effects of sediment parameters on the multi - path arrival structure , the algorithm of the ssp inversion using multi - path arrival time differences and the ssp inversion based on matched beam processing ( mbp ) . 1 采用理论分析、数值仿真方法研究了沉积层参数对浅海多途到达结构的影响；推导和论证了到达时差反演浅海声速剖面算法、提出和研究了用匹配波束处理反演浅海声速剖面算法，并且应用东中国海实验数据对这两种算法进行了验证。
The studies of circulation in ecs were most based on the analysis of temperature and salinity data and diagnostic mode . aim at breaking this limitation , we had established a quasi - predictive model in the ecs by reconstructing the pom model to overcome the difficulties brought to the simulations by steep terrain and great density gradient in the new model , the monthly mean sst data in the ecs and the result of global ocean model were used as the boundary conditions to simulate the distribution of the temperature and the circulation structure in the ecs 针对以往温、盐资料分析和模式诊断方法为主的东中国海环流研究的局限性，通过改造pom模式，克服因陡峭地形和大密度梯度给模拟带来的困难，建立了东中国海环流准预报模式，运用本文第三章获得的sst资料和全球大区模式的结果作为模式的边界条件，模拟了东中国海温度分布与环流结构。
In the tsushima strait , the annual mean flux was 2 . 3sv and its monthly variation just was only 0 . 4sv . the thermockne structure and its variation affected the circulation system in the ecs . the weekly and monthly mean sea surface temperatures ( sst ) in the ecs were obtained by analysis and calibration of sst data from satellites during 1990 - 1999 通过获取、分析和校正1990 - 1999年间逐周的卫星遥感海表温度资料，并通过最优插值技术获得东中国海18x18km周平均和月平均海面温度场，论文还系统分析了东中国海月平均海表温度场的分布特征。
Based on mom2 model , a 3 - dimentional prognostic baroclinic z - ordinate model was established to study the circulation of east china seas , considering the real topography , inflow and outflow on the open boundary , wind stress , temperature and salinity exchange on the sea surface . the results are consistent with observation 本文基于mom2建立了一个三维斜压预报模式，采用真实海底地形，利用东中国海海面风应力、温度和盐度作为海面定解条件，并考虑其与外海界面处水体交换及温盐通量，对东中国海的冬季斜压环流实施了数值模拟研究。
