An ecological study on the fouling organisms in Yantai Harbour

Yantai Harbour (37°33′15″N , 121°23′42″E) is situated at the north coast of Shandong Peninsula and is a large fishing and commercial port of North China. From June 1983 to May 1984, a yearly panel test on fouling organisms was carried out at the non-fixed jetties in the inner and outer harbour. The test method was according to "the Marine Survey     

On the radiation and diffraction of linear water waves by an infinitely long rectangular structure submerged in oblique seas

The radiation and diffraction of linear water waves by an infinitely long rectangular structure submerged in oblique seas of finite depth is investigated. The analytical expressions for the radiated and diffracted potentials are derived as infinite series by use of the method of separation of variables. The unknown coefficients in the series are determined by the eigenfunction expansion matching method. The expressions for wave forces, hydrodynamic coefficients and reflection and transmission coefficients are given and verified by the boundary element method. Using the present analytical solution, the hydrodynamic influences of the angle of incidence, the submergence, the width and the thickness of the structure on the wave forces, hydrodynamic coefficients, and reflection and transmission coefficients are discussed in detail.     

普里兹湾陆缘水边界的变化

利用１９９８年１１月－１９９９年２月中国第１５次南极考察资料,讨论了普里兹湾附近陆缘水边界（ＣＷＢ）两侧的水团分布,以及ＣＷＢ的中心位置、锋面宽度、锋面强度、锋面的垂直深度和垂直厚度等物理特征的空间变化。并与１９９２年１２月－１９９３年２月中国第９次南极考察资料进行了比较,说明了ＣＷＢ的时间２变化。同时,还进一步分析了ＣＷＢ两侧海水运动的各向异性,以及动力高度场的形势,指出了动力高度槽,ＣＷＢ锋面

头足类视觉特性的电生理研究 Ⅰ.无针乌贼视网膜电图的特性

乌贼是重要的海洋水产资源之一,对其视觉特性的研究在理论上和实践上显然都有一定的意义。视网膜电图(ERG)作为网膜的综合电活动是反映视觉特性的一个良好指标。乌贼的ERG的特性至今缺乏系统的研究。本文对其ERG的波形和适应特性作了较详细的描述。续文将报导对ERG的光谱敏感性的分析。     

东海黑潮及琉球群岛以东海流研究进展

东海是西太平洋的一个边缘海,它西部有广阔的大陆架,东面以九州岛、琉球群岛(由奄美诸岛、冲绳诸岛、先岛诸岛组成)和台湾岛连线为界,具有较深的海槽。黑潮是一支高温、高盐、高流速的西边界流,它起源于菲律宾以东海域、流经台湾东岸进入东海,沿东海大陆架外缘向东北向流动，穿越吐噶喇海峡返回太平洋。通常的把自台湾东北端起至吐噶喇海峡一段称为东海黑潮。此外,在琉球群岛以东海域也常年存在一支稳定的西边界流,称为琉球海流。 对于东海黑潮和琉球海流的硏究,主要起步于20世纪80年代,通过进行中日联合调查研究、中日副热带环流调查研究等,取得了许多重要成果,苏纪兰(1994)、袁耀初(2000，Yuan,2006)、管秉贤(2002)等人都做过评述。本文基于以上研究评述,主要叙述200年以来对东海黑潮及琉球海流的硏究新进展。     

海浪日最大波高序列的一种标度性质

应用重标度分析方法研究小麦岛海洋观测站１９６１－１９８０年二十年海浪日最大波高序列时发现，该序列并不是相互独立的，而是具有记忆性和持久性，详细的论证表明分式布朗运动模型是描述海浪日最大波高序列的一个较好的模型，同时，应用分式布朗运动模型我们找到了存在于海浪日最大波高序列中的一种标度性质－累积离差（ｔ）的统计自仿射性。
