台湾暖流起源的研究

根据台湾东北海域的水文资料分析,作者对台湾暖流起源提出以下看法:台湾暖流起源于黑潮分支和台湾暖水,黑潮分支为主要源泉。台湾暖流的深层水完全来自黑潮分支的深层水,不具有暖流性质,而其上层水是由黑潮分支的上层水和台湾暖水组成。由于台湾暖水有明显的季节变化,与此相应,台湾暖流也发生相应的变化。     

溴素的有机化学──Ⅴ.溴代脂肪酸—2,3,5,6—四溴—1,4—苯二酯的合成

以1，4—苯二酚和不同的短链脂肪酸为基本原料，经溴代、加成、形成酰卤和酰化等反应，合成了六种新的溴化脂肪酸—2，3，5，6—四溴—1，4—苯二酯。通过对产物的碳、氢、溴等元素的定量分析，以及红外吸收光谱和氢核磁共振谱的研究，验证了化合物的结构。     

台湾海峡上升流区底栖生物数量动态的初步研究

不同季节底梄生物数量的动态由其组成种的种群特点所决定。在一些生命周期短(一年左右)、生长速度快(新生个体当年可以长成)的种处于优势的情况下,生物数量的季节变化就比较显著;而生命周期长、其种群由多个年龄组的个体构成的种占优势的情况下，一年之中种群数量就相对稳定。另一方面,底栖生物数量的急剧改变又决定于经济种的捕食活动和优势种的生物学过程。台湾海峡系经济鱼、虾类的集中分布区,尤以上升流区范围内的集群最密集。为了便于深入研究上升流与经济鱼、虾类资源的关系,本文着重探讨上升流范围内底栖生物数量的动态特点。

大窑湾海域水化要素分布及相关关系的探讨

本文依据大窑湾的环境调查资料为基础，系统地阐述了水体中化学要素ｐＨ、盐度、透明度、ＤＯ、ＣＯＤ、ＴＯＣ、浊度、悬浮物、ＮＨ４－Ｎ、ＮＯ２－Ｎ、ＮＯ３－Ｎ、ＰＯ４－Ｐ、ＳｉＯ３－Ｓｉ、Ｃｕ、Ｐｂ、Ｚｎ、Ｃｄ、Ａｓ、Ｈｇ、Ｃｒ、硫化物、六六六、石油等分布规律。诸要素主要是在潮流水动力支配下，形成扩散带。各要素中仅有无机氮和ＰＯ４－Ｐ两项含量超标，其余要素含量范围都是处于海水正常浓度水平，属于一类海水水质。文章并对各要素进行相关关系分析。     

济州岛南部海区的双跃层现象

本文分析了济州岛南部区域温度双跃层现象的类型及其成因。特别阐明了双跃层的波状现象,指出:强流锋区的侧向效应,黑潮次—中层混合水的爬升,黄海冷水团边缘密度环流引起的侧向流动,以及上、下层流速、流向不一致引起的剪切作用,是导致双跃层波状现象的主要原因。发现上、下跃层之间存在着“跃层间环流”,这是一个有趣的海洋学现象,它将导致双扩散的发生和有利于双跃层的维持。     

Morphology, reproduction, ecology and isoenzyme electrophoresis of Capitella complex in Qingdao

-Morphology, reproduction, ecology and isoenzyme electrophoresis of a Capitella complex in Qingdao were examined from 1983 to 1984. We determined that the Capitella complex in Qingdao was composed of at least three sibling species: Capitella cf capitata, Capitella sp. I and Capitella sp. IT. Although these three species are very similar in morphology, they differ in: three kinds of isoenzyme electrophoresis, staining reactions, developmental pattern, larval morphology and dispersal, reproductive strategies, breeding season and population ecology. In addition, they show a series of minor quantitative variations in adult morphology, especially in number and morphology of setae. Such differences can be detected only at the population level. Some ecological data such as density, growth rate, mortality and sex distribution are also provided in this paper.     

Cross-equatorial flow and its effects on the hurricanes occurrence over the Southern Hemisphere

Channels of cross - equatorial flow and their characteristics Winds at every 5 deg. grid point from 30°E to 180° over the equator at 850 hPa and 200hPa from December 1984 to February 1985 have been separated into U(zonal wind) andV(meridional wind).The V component has been used to represent cross- equatorial flow. FromFig. 1 we obtained that as during the Northern summer,there are also severa1 regions in which     

Siltation Prediction for Navigation Channels and Harbour Basins on Muddy Beach

- This paper, after briefly reviewing the experimental research on sediment transport on muddy beach since the 1950s, improves and perfects the method for forecasting siltation in navigation channels and harbour basins which was first put forward in China by the authors. In consideration of silty sediment and sand, some factors in forecasting methods have been changed and modified. Consequently, the modified methods can be used either to compute siltation in navigation channels and harbour basins on muddy beach or to compute siltation and scouring in navigation channels and harbour basins on both silty beach and sandy beach. The verification of field data from eleven large, medium and small natural harbours shows a good agreement between the forecasting by the modified method and the natural conditions. Finally, the paper deals with the rational utilization of water area after the construction of the West Dyke in Lianyungang, the maintenance of water depth of the navigation channel at the entrance, siltation distribution, siltation in the navigation channel and harbour basin for ships of 100 thousand tonnnage. Results once again prove that the prospect of constructing Lianyungang Harbour into a deepwater harbour is bright.
