珠江口伶仃洋温度分布特征

依据实测资料，分析了伶汀洋冬、夏季的水温分布特征及其变化。冬季湾内水温的分布和变化较单一，夏季由于河流入海流量增大，河流与海洋水体的相互作用加强，明显可见两个冷、暖水锋在河口湾中段相交，上段为高温的河流淡水控制区，下段为低温的陆架水控制区，两者显著的特点是其控制区内温度变化很小，而在锋面转折地带的河口湾中段，盐淡水混合强烈，其温度变化大，温度等值线呈倾斜分布。     

N,N-二烷基酰胺类物质的膜状态及其在水面溢油集油剂中的应用研究

合成了 5种 N,N-二烷基酰胺型表面活性剂 ,并对其所成膜的状态进行了测定。表明当N,N-二烷基酰胺类物质单独成膜时获得的集油膜为多层膜 ,而当选用合适的溶剂与其配制成溶液以后 ,所成的集油膜则为转变膜或液态凝聚膜。在 5种 N,N-二烷基酰胺类物质中 ,酰基碳链越长、氮烷基碳链越短则其集油能力越强。应用 N,N-二烷基酰胺类物质配制了 4个配方 ,均具备良好的集油能力 ,并且对原油的集油能力大于对柴油的集油能力

海岸沉积物中微量金属的早期成岩作用行为用作指示过去生成环境的变化

沉积物中有机质在氧化降解作用时，结合态金属Ni、Cu和Cd被释放入孔隙水中和返回水柱中．海岸沉积物的最上部沉积物层的孔隙水中，溶解的Cu．Ni和Cd通常比底层水富集．在较深的缺氧沉积物中，溶解的金属含量一般较低．     

珠江河口西南风强迫下潮流场的数值模拟

采用Backhaus三维斜压模型模拟了均匀西南风场对珠江口近岸海域的影响，并与无风情况作了对比；通过对珠江河口盐度场及风生环流的分析比较，结果表明，模型较为真实地再现了夏季珠江河口的水动力学特性。     

Stuidies on the Technology for Mass Production of Abalone Breeding

Based on the traditional way of abalone breeding,the technological process of industrial abalone breeding suitable for the coastal areas of southern China has been developed.The process is simple and easy to handle,and results in a high yield of young abalones after being applied.     

浮体间距对多浮体系统水动力系数的影响

根据三维线性势流理论，采用格林函数法，对多浮体系统的水动力系数进行了数值分析。数值算例中给出了在固定波频下水动力系数与浮体间相对位置关系曲线。水动力系数的变化幅度随着浮体间距离增大而变小。随着浮体间距的变化，水动力系数极值的出现具有明显的规律，相邻的极大值(或极小值)的间距为半个波长或一个波长。     

Elemental geochemical records of seafloor hydrothermal activities in the sediments from the Okinawa Trough

The major and minor element contents in the sediment core H9 from the hydrothermal fields of the Okinawa Trough show a sharp change at the depth of 80 cm. The elements enriched in the upper 80 cm core are those enriched in the hydrothermal deposits and in the surface sediments recovered from the hydrothermal fields in the trough, which indicates the input of hydrothermal materials. Comparing with other hydrothermal sediments from Mid-ocean Ridges or the Lau Basin, the degree of the enrichment of elements iron, copper,cobalt, and nickel is relatively low. However, the enrichment of elements manganese, lead, arsenic, antimony and mercury is remarkable. The average contents of these elements in the upper 80 cm core sediments are three to six times those in the lower section, and 3~12 times those in the surface sediments which are not influenced by hydrothermal activities. Hydrothermal activities have contributed significant manganese, lead, arsenic, antimony and mercury to the sediments, and these elements are distinct indicators for the hydrothermal activity in the Okinawa Trough. The significant enrichment of these elements in Core H9 upward from the depth 80 cm indicates the start or the significant enhancing of the hydrothermal activity in this area at about 5 740 aB.P. The average accumulation rate of manganese during this period is about 40 461 μg/(cm2·ka), which is similar to the hydrothermal sediments in the Lau Basin or the East Pacific Rise.     

黑潮水入侵南海的水文分析：Ⅱ.1994年8—9月期间的观测结果
