The paper is organized as follows. In chapter 2, we introduce some concepts about SEA, the abstract SEA model and the convergence definition of algorithm. In chapter 3, we describe firstly the evolution of PMA as an abstract stochastic process, and by characterizing axiomatically the properties of the fundamental selection and evolution operators, we conclude that PMA is essentially a kind of SEA.

本文结构安排如下：第二章介绍了模拟进化算法的一些基本概念、形式化随机过程描述以及收敛性定义；第三章对改进后的 PMA 各操作作了抽象定义，得到了 PMA 的形式化随机过程描述，并公理化地证明了各操作算子为选择或繁殖算子，从而得出 PMA本质上也是一种模拟进化算法；第四章先对选择算子特征数定义作了适当改进，并通过各进化算子的具体特征数指出，如果 PMA 不采取任何执行策略时，算法本身并不收敛。

ABSTRACT The Yellow River delta located in the land and sea interaction zone and is being formed with the coaction of the River and Bohai sea. The three parts of the whole delta, i. e. the delta plain, tidal zone and submerged delta, are in different dynamic environments. The delta plain is controlled by the land surface processes. The tidal zone is under the coaction of the river and the sea.

黄河三角洲处于海陆交错地带，是河流与海洋因素共同作用的堆积体，从陆上三角洲平原到潮间带直至水下三角洲受不同动力因素的作用，陆上三角洲平原主要受陆地表层过程的影响；潮间带受陆、海动力的共同作用，而水下三角洲主要受海洋动力的作用。

This paper analyses the regional relative changes in sea level and causes along the east China coast over the last decades, and concludes that there are different features for south and north of the Changjiang Estuary, the relative sea level rises along the south coastline, while alternate rise and fall occurs along the north, which is associated with tectonism and eustatic sea level change.

本文对近期中国东部区域性海平面相对变化和原因进行了分析与探讨，得出了以长江口为界的中国南北沿岸海平面的差异特征。长江口以南的相对海平面主要表现为上升趋势，而以北则呈交替升降变化。这主要与全球性海平面变化和中国东部沿岸现代构造运动有关。

Based on the high-resolution analysis of planktonic foraminiferal isotope and organic carbon of 91 sediment samples from two box cores located respectively in the southern and northern slopes of the South China Sea, the changes of sea surface temperature and paleoproductiviy of the past 2400 years were reconstructed. The sea surface temperature and the depth of thermocline varied in different stages during the late Holocene, with some short-term climate events such as the Little Ice Age.

对南海南、北陆坡两个箱式柱状样中91个沉积物样品进行了高分辨率的稳定同位素和有机碳分析，获得最近2400年以来上部海水温度和表层古生产力的记录，发现晚全新世南海的表层海水温度和温跃层呈现阶段性变化，且有小冰期等短期气候事件。

Thus, for three tropical cyclones occurred on different regions, three sets of altimeter-derived data of the sea surface wind and wave are selected, their structural features and relations between the wind and the wave under the influence of the tropical cyclones are analyzed respectively, finally, the most frequent occurring relations between the sea surface wind and the wave of the tropical cyclone over the South China Sea and two hindcast methods for wind field of typhoon based on altimeter-derived wind speed are presented.

据此，选取了高度计获取的3个出现在不同海域的热带气旋影响下的海面风、浪资料，进一步分析各个气旋影响下的海面风、浪结构特征及其关系，并给出了南海海域气旋海况下最可能的海面风、浪关系以及基于高度计风速资料的两种台风风场后报方法。

On the basis of sea resources analysis, some argues of important scientific theory and technological assembly in the exploitation of oceanic resources are discussed in the paper, such as the technological assembly of deep-sea creature resources commercial applications, the study on the hydatogenesis of sea bottom, the study on the reaction between water and rocks, the discriminating and exploitation technology of natural hydrate and solid metallic deposits.

在各种海洋资源可利用性分析的基础上，针对应用开发，提出的海洋资源开发中的重大科学理论与技术集成应引起科学界与管理部门的充分关注，包括深海生物资源商业应用开发的技术集成、海底热液成矿作用理论研究、水－岩反应研究、天然气水合物与固体金属矿产的识别与开采技术集成。

On the one hand, The empirical model is remedied to investigate themicrowave emissivity of sea surface under wave breaking. In this model, we havediscussed the effects of spherical bubbles and droplets of whitecaps and difference intemperature between air and sea water on the emissivity of sea surface. Themodel results indicate that the effective seawater emissivity increases with DTBASincrease.

在被动遥感方面提出了一个改进的研究海浪破碎产生白冠时海水有效发射率的模式，讨论了白冠层中主要成分为球形气泡和水滴的情况，并着重分析了海-气温差对海水发射率的影响，研究表明海水发射率随着海-气温差的增大而增大。

We,therefore,suggest that the kuruma shrimpin the East China Sea and the Taiwan Strait can be discriminated into two stocks.One isin the north of the East China Sea,and the other is in the south of the East China Sea andthe Taiwan Strait.

因此，东海及台湾海峡产斑节虾应可分为二个系群：一为东海北部群；另一群则分布於台湾海峡与东海南部。

When sea level drops, forced by Kelioli, river mouth extends eastward and migrates southward, cutting down deeply. On the contrary, when sea level rises rapidly, river mouth jumps northward dramatically and moves westward, goes backward step by step. While sea level changes and river discharge is harmnize, as the geological depositional center is moving eastward and southward, driving by Keliolli and longshore drift, river mouth moves southward slowly, keeps relative stability, and forms the delta towards south slightly.

海面下降过程中，河流河口在科氏力作用下，南移东伸，下切迅速；反之，海面快速上升的过程中，河口则迅速北跳西移，逐步退缩；两者力量对比相当时，在沉降盆地沉降中心东移，并向南掀斜的背景下，在科氏力与沿岸流作用下，发育微微南偏的三角洲，河口缓慢南移，相对稳定。
