两层分层流体中初始内孤立波分裂的数值研究

本文导得了1个研究内波分裂的射线型二维KdV方程。利用这一方程的一维退化方程进行了实验室尺度下孤立子型内波分裂的数值研究。数值结果表明,深水区的初始内孤立波和实测的内孤立波(内潮)在通过陆坡区时都会产生分裂,并在陆架上(浅水区)生成一内孤立子波列。这表明在实际海洋条件下,深海区内潮的分裂是陆架上海洋内孤立子波包(或波列)生成的主要机制之一。     

Investigation on the Deposition in an Excavated Trough at the East Shore of Jiaozhou Bay, China

- Based on field investigations, this paper analyzes three types of harbour basinns and navigation channel excavated on seabed in Jiaozhou Bay, get a general rule of deposition for excavated trough, it found that pollution is one of crucial factors resulting in the deposition of the excavated trough in the east shore of Jiaozhou Bay. With these results, it predicted the annual deposition thickness for the excavated trough and disclosed the fact that it can't be deposited deadly during one storm. At the same time, with two-dimensional numerical model, it studied the effects of the excavated trough and the reclamation near shore on tidal cureent and said that the excavated trough can decrease the current velocity passing through the trough about 10- 15%, but only limited inside and near the trough and there are no effect on other regions; reclamation can cut off the pollution sources and no obvious effect on the currents of the Jiaozhou Bay. Connecting the deep trough and Cangkou tidal channel with a new     

南极磷虾年龄组成的体长频数分布混合分析

本文依据１９８９／１９９０和１９９０／１９９１两个南极夏季在普里兹湾以北海域所获的拖网样品，应用分布混合分析方法，研究大磷虾种群的年龄结构。结果表明，种群内最多可能包括６个年龄：发年幼体，１＾＋，２＾＋，３＾＋，４＾＋和＾５＋龄虾。     

青岛文昌鱼的生活史──年龄、生长和死亡研究

于１９８９年８月－１９９０年７月对青岛文昌鱼的生活史进行研究。结果表明：（１）青岛文昌鱼种群由４个齿组组成，它至少生产４ａ以上，甚至可达６ａ左右。（２）在Ⅰ、Ⅱ齿时生长较快，平均年生长１３－１５ｍｍ，Ⅲ龄后生长速度减慢，即使同一年龄组的文晶鱼，在不同季节其生长速度也不同。（３）在冬春采集的文昌鱼中Ⅲ龄组的峰值较小。（４）繁殖季节过后，老龄文昌鱼因衰老而死亡。     

中国马尾藻属的研究Ⅲ.丛伞托序族

对中国马尾藻属，真马尾藻亚属，滑托组，丛伞托序族的种类进行系统研究。此族种类的主要特征是生殖托光滑，聚伞状排列在小校上，生殖托柄状部位都有生殖窝。多孢马尾藻是该族的非常特殊种类，它的分校和小分枝上密生刺和羽状分裂的藻叶。文中还报道了一个新种一长干马尾藻。模式标本产自广东省徐闻，还见于海丰。至今为止，丛伞托序族在中国共有两种。     

不同生长期坛紫菜多糖中组分含量的变化

于１９９０－１９９１年，运用＾１３Ｃ－ＮＭＲ和化学分析方法研究南方产和移植北方养殖的不同生长发育阶段坛紫菜多糖的组分变化，结果表明，随着藻体生长发育，坛紫菜琼胶中３，６－内醚－Ｌ－半乳糖和６－ＯＣＨ３－Ｄ－半乳糖的含量逐渐增加，而硫酸基的含量呈现先增加后减少的规律；北移坛紫菜琼胶中３，６－内醚－Ｌ－半乳糖的含量高于南方坛紫菜，而硫酸基和６－ＯＣＨ３－Ｄ－半乳糖的含量低于南方坛紫菜。

黄茅海河口湾现代动力地貌体系和冲淤过程分析

1980—1993年对黄茅海河口湾进行沉积物采样和水流测定及水深测量。根据水动力和地形条件，冲淤分析及Mclaren模型研究河口湾的动力地貌体系、冲淤特征和现代沉积物运移。结果表明：（1）水下地形主要为下泄流或上溯流控制的“深槽－槽沟－浅滩－湾口”的动力地貌体系，反映了河口湾“东进西出”的水流格局；（2）整个河口湾以淤积为主，只有崖门深槽有较明显的优势冲刷特征，并随着崖门深槽向海推移和河口湾“东进西出”水动力作用，黄茅海落潮三角洲相应向西南进积；（3）应用Mclaren模型揭示了黄茅海河口湾现代沉积物运移规律，同样反映了河口湾具有“东进西出”的运移趋势。     

A three-dimensional ocean general circulation model for mesoscale eddies——Ⅱ Diagnostic analysis

A three-dimensional density field associated with mesoscaie unstable waves generated by the 3-D, primitive-equation model (Wang and Ikeda, 1996) is provided to the quasi-geostrophic pressure tendency and ω-equations, and to the (ageostrophic) Q-vector equation. Diagnostic analyses, analogous to the approaches in meteorology: ω-equation and Q-vector method, are for the first time developed to examine the mesoscaie dynamical processes and mechanisms of the unstable waves propagating in the mid-latitude ocean. The weaknesses and strengths of these two diagnostic approaches are evaluated and compared to the model results. The Q-vector method is then recommended to diagnose the vertical motion associated with the mesoscaie dynamics from a hydrographic CTD (conductivity-temperature-depth) array, while the quasi-geostrophic equations produce some small-scale features (errors) in the diagnosed fields.
