成山卫沙坝潟湖链的形成和近期演化

山东荣成市成山头南侧发育了一条沙坝和一系列的湖 ,组成成山卫湖链 ,以面积最大的天鹅湖有关资料为主 ,运用粒度分析、软体动物鉴定、14 C测年等方法 ,对So5 ,Sh5 ,Sh1和Sh6孔岩心进行分析 ,揭示了该湖链的形成过程 :距今 70 0 0a左右 ,海水开始入侵 ,形成了荣成湾 ,距今 6 0 0 0a左右 ,沙坝和坝内的一系列半封闭湖形成 .根据沙坝层理的观测资料分析了湖形成后自然作用下的演化动态 ,并指出近年来由于人类活动加剧 ,严重影响了湖的演化过程     

鱼类消化道细菌及其作用研究Ⅱ.鲻鱼

本文报道了从鲻鱼消化道分离的好气性异养细菌数量为（1．5×108±0．4×108～6.4×108±2.0×108）个／g，共分离220株细菌。其种群组成为弧菌、气单胞菌、不动细菌、假单胞菌、微球菌、黄杆菌、葡萄糖细菌、纤维单胞菌、节细菌和棒状杆菌。测定其生化特性，表明该类菌对有机质的分解能力比较强，这些特性有利于鱼类对营养物质的消化和吸收，并进一步促进其生长和发育。     

九州西侧海域129°E断面的流速和温盐结构特征

根据中、日合作黑潮调查研究期间（1987－1993年）在九州西侧海域获得的水文资料，计算了129°E断面的地转流速和流量。着重提出129°E断面北侧存在一支较稳定的西向流；分析这支西向流的去向，指出它是向对马暖流输送黑潮水的重要途径；给出了这支西向流及黑潮通过该断面的流速、流轴、流幅及流量的变化特征。     

新生相形成的模拟实验研究

通过模拟实验制备了硅酸盐类不溶性固体，从Ｘ射线衍射特征和红外光谱特征两方面看，制得的硅酸盐类与河口新生相成分，结构相似，表明铁水解成的β－ＦｅＯＯＨ胶体吸附Ｓｉ，Ａｌ，Ｍｇ，Ｋ等元素，经结构重组可形成硅酸盐矿物，这可能是河口体系新生相的形成原因。     

假晴东方鲀人工育苗研究

假晴东方鲀人工育苗获得４１．８ｍｍ种苗３５１０００尾，每立方水体出 苗８６０尾。越冬成活率９１．６％，增重率６１．８％。利用室内水泥池及养虾土池 养成商品鱼，分别获得１９６９ ｇ／ｍ３和 ２０８ ｋｇ／亩的收成。     

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。     

厌氧沉积中有孔虫组合特征

厌氧沉积的有孔虫组合中,底栖有孔虫主要由Bolivina诸种和Buliminella tenuata组成,同时含有少量厌氧标志种Suggrunda eckisi;浮游有孔虫中以Globigerrina bulloides和G.quingueloba为数较多。底栖有孔虫与浮游有孔虫数量相比,浮游有孔虫数量很少。     

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.
