渤海湾及其附近海域沉积物中Cu,Pb,Zn,Cd环境背景值的研究

根据渤海湾及其毗邻河口区10柱岩芯样细颗粒（＜0．063mm）（GF 1983－1985年采集）中重金属含量特点，结合^216Pb年代学编年资料，用未受人类影响沉积层中元素含量，藉统计学方法获得渤海湾岩芯样中Cu，Pb，Zn，Cd的分布类型，并根据各区重金属的含量水平，用t检验法获得了渤海湾Cu，Pb，Zn，Cd的环境背景值。     

中国陆架海绿石分布特征及其意义

本文根据实际资料,简要概括了中国大陆架海绿石的分布规律和形成环境。海绿石的富集区与氧化环境,粗粒沉积和残留沉积区相一致。该研究为恢复古沉积环境提供了依据。     

A NUMERICAL COMPUTATION OF THE WIND-DRIVEN CURRENT IN THE BOHAI SEA

On the basis of shallow water equations, a 2-dimensional model for the wind-driven current is developed in this paper to simulate the mean wind-driven circulation and sea-surface elevation fields respectively in winter and summer, and to describe the general nature of the wind-driven current in the Bohai Sea.Numerical results show that the patterns of the wind-driven circulation in Bohai are mainly the cyclonic circulation in winter and both cyclonic and anticyclonic circulations in summer. A theoretical argument based on vorticity is put up to explain the generating-mechanism of large eddies near the strait, which are considered to be the direct results of the wind stress interaction with topography gradients.     

Annual and interannual variations of large-scale circulation over the tropics as revealed from OLR data

In this study, the outgoing longwave radiation (OLR) data of eight years have been used to investigate the annual and interannual variations of large-scale circulation over the tropics. The results of EOF analysis indicate that the first three eigenvectors reflect the essential features in OLR annual variation. However, they contribute little to the interannual change. In comparison, the fourth to the sixth components have very large year-to-year variations. The pronounced anomalies are located over the tropics with east-west dipole pattern. It implies that ENSO events are related closely to the variation of the Walker circulation.     

海水盐度对牙鲆仔稚鱼的生长、存活率及白化率的影响

１９９３年１１月２０日自鹿儿岛养殖业购得自然产卵获得的牙鲆受精卵，经空运、陆驼至福冈的九州大学附属水产试验所，仔鱼翌日孵出，３ｄ后开口。以此材料观察研究试验室条件下不同海水盐度对牙鲆仔稚鱼的生长，存活率及白化率的影响。试验分４组，盐度分别为：１组（自然海水对照组），３０．５－３１．８；２组，２６．０：３组，２１．０；４组，１６．０。每组设２个重复，使用１００１透明玻璃钢水槽，每槽放２０００尾刚开口

超浅海风暴潮的数值模拟(一)——零阶模型对渤海风潮的初步应用

由我国北方的寒潮或冷空气所引起的渤海风潮,按文献的分析,该属于“超浅海风暴潮”类型.以渤海风潮为例,按超浅海风暴潮理论进行数值计算,不仅对该理论是一有力的检验,且对探讨渤海风潮的机制和预报也是一个有益的参考. 将冷锋所造成的大风风场重现在计算网格上,在现场海面风资料极度贫乏的情况下,显然是一较难的课题.本文仅就发生渤海风潮时,渤海上空风场的几个主要力学特征,设计了几个理论模式风应力场,对渤海风潮进行了数值计算,以期获得全过程概貌及主要特征.计算结果达到了这一预期目的.     

我国东部邻海恶劣天气的时空分布及其成因初探

本文利用1930～1979年NCDC海洋船舶观测的气象资料,分析了中国东部邻海恶劣天气的时空分布。结果表明,海区恶劣天气的分布在冬季和夏季是不同的;在东北和西南季风期间,台湾东北和西南海区也有差异。影响恶劣天气条件的分布因子非常复杂,主要是季风和极锋、天气系统、冷暖洋流及地形等因子。     

磁通门罗盘的原理

磁通门罗盘是一种新型罗盘。此罗盘的关键部件是探头,探头主要是由高导磁的软磁材料做成的磁环和线圈组成。当在初级线圈加上交变的激励信号时,即可得到与次级线圈在地磁场中相对应的磁方位角。本文介绍其原理,并对其进行了理论分析。
