The Pan-Pearl River Delta region is located at a juncture connecting China with ASEAN countries, bordering with several ASEAN countries and sharing with them more than 5,000 kilometers of border demarcations. It is linked with ASEAN countries by rail, road, water and air accesses. The Pan Pearl River Delta is located on the forefront of China's economic interaction and win-win cooperation with ASEAN. This gives the region a unique geographical advantage in the course of building the China-ASEAN FTA.

Simulation and prediction of reservoir lithology is one of the main subjects of reservoir sedimentology and oilfield production. By fan-delta lithology simulation study, a set of technology about reservoir structure simulation and prediction of fan-delta had been established. Through test calculation of different lithologies by using many simulation methodogies, the best simulation methodology for this depositional system had been determined and it is proved to be reliable by practice.

储层岩石相的模拟与预测是储层沉积学和油田实际生产的主要课题之一，通过对扇三角洲露头岩石相的模拟研究，总结出了该类扇三角洲沉积体储层建筑结构的模拟与预测方法，经对不同岩石相多种模拟方法的试运算，给出了对于该类沉积体系的最佳模拟方法，并通过实际检验证明是可信的。

Separate chapter merits the Ebro's delta, to the one that the report augurs little future: Forecast than, due to the rise in waters of the sea level, half the system the little delta will disappear before 50 years.

单独的一章，值得引起ebro的三角形，将其中的说，该报告预示着小的未来：比预测，由于上升海域的海平面的一半，系统的小三角洲将消失之前， 50年。

Sediment from river is not the main source of the Rushan Bay now any more ,which leads to the change of balance of sedimentation power. Sediment will transport because of the drive of hydrodynamic elements in macroscopic view .Direction of suspended load is basicly the same as tidal current .Flood tide makes suspended load transport to tip of the inner Bay and to the Mouth in exterior Bay .The direction of longside sediment transport in two sides of the Mouth mainly focus in the Mouth .Because the coastline along the exterior Bay is very meandering and it belongs to the type of bedrock ,besides some sediment going into the inner Bay ,so actual net sediment discharge rate is less than calculation .It develops an ebb delta out of the Mouth and forms tidal sand ridge ,tidal washing canal ,barrier bar and marine physiognomy ;The result of model simulation disclosures that differences of sediment erosion and siltation between single tidal action and wave-current action are very big .From the analysis of sediment composition、sediment sources and stability of beach and ridge ,this article gets the conclusion that the channel has the possibility to silt ,though the course maybe very slow.

通过分析研究文章得出如下结论：沉积物平面分布与水动力的时空变化存在很好的相关性；口门外发育落潮流三角洲，形成潮流沙脊、潮流冲刷槽、浅滩、拦门沙等水下动力地貌；乳山湾河流来沙已不是湾内泥沙主要来源导致沉积水动力平衡发生改变，宏观上表现在泥沙受水动力驱动发生不断运移；悬沙运移方向与涨潮流方向基本一致，湾内涨潮流带来的悬移质泥沙向湾顶运移，湾外悬移质泥沙主要向口门方向运移；湾口两侧岸段沿岸输沙方向均指向口门方向，由于乳山湾外海岸线曲折，两侧岸段以基岩为主，加之部分泥沙进入湾内，实际净输沙量小于计算值；数值模拟发现潮流单独作用与波流共同作用下泥沙蚀淤模拟差别较大；从沉积物组成、泥沙来源及滩槽稳定性三个方面分析，文章认为研究区存在航道淤积的可能性，但过程相对较慢。

Boundary polynomial point interpolation mesh-free method and boundary radial point interpolation mesh-free method were presented, based on polynomial basis and radial basis respectively for transient eddy current analysis, and their interpolation shape functions satisfy the Kronecker delta function and the essential boundary conditions can be directly imposed on the boundary nodes. An example on analyzing transient eddy current of a square metal column was set to prove the validity of the proposed methods, and a comparison on accuracy between BPPIM and BRPIM was analyzed as well.

运用多项式点插值法和径向基点插值法构造形函数，推导了适合于工程电磁场瞬态涡流问题的多项式基点插值边界无单元方法和径向基点播值边界无单元方法，这两种方法的空间插值形函数满足Kronecker delta条件，从而强加边界条件可以直接施加在边界点上，以金属长方柱的瞬态涡流分析作为数值算例，证实了两种方法的正确性和有效性，并对两种基类的点插值法进行了精度分析和比较。
