地形坡度对斜压大气扰动的影响

本文推导出σ坐标系斜压大气的准地转位涡方程，该方程形式与Ｐ坐标系的准地转位涡方程非常相似，但本质不同，本文还用ＷＫＢ方法讨论了大地形坡度对斜压大气扰动发展的影响。指出：东西走向山脉的南坡有利于低层大气槽线呈西北－东南向的扰动发展，也有利于高层大气槽线呈东北－西南向的扰动发展

Action of Cnoidal Waves on Vertical Walls

Based on the 2nd order cnoidal wave theory, the characters of shallow water standing waves and their action on vertical walls are studied in this paper. The theoretical expressions of the wave surface elevation in front of and the wave pressure on the vertical wall are obtained. In order to verify the theoretical results, model tests were made in the State Key Laboratory of Coastal and Offshore Engineering at DUT. For the wave surface elevation in front of the wall and the wave forces on the wall at the moment when the wave surface at the wall surface goes down to the bottom of the wave trough, the calculated results coincide quite well with the experimental results. For the wave forces on the wall at the moment when the wave surface at the wall surface goes up to the top of the wave crest, the theoretical expressions are modified by the experimental results. For the convenience of practical use, calculations are made for the wave conditions which usually occur in enginering practice by use of the inves     

臭氧化消毒技术在海水消毒中的应用

本文从理论出发，通过大量的小型模拟实验，确立了海水流量、臭氧投加量、消毒时间三者的关系，从而制定了利用臭氧进行海水消毒净化工程的工艺流程。又经过实际工程的验证，其工艺流程是可行的，结果优于设计要求，从而创立了国内第一家利用臭氧进行海水消毒净化的优质工程，为沿海城镇以海水替代淡水提供了一个新的途径。     

On the monitoring of the thermal state of the upper ocean

This paper discusses some problems related to the development of systems of global monitoring of the sea surface temperature (SST). The characteristics of the operational SST data are considered and estimations of their accuracy are given. The applications of varoous models to the computation of SST in relation to the development of an oceanographic data assimilation system are reviewed briefly.Translated by Mikhail M. Trufanov.

贻贝育苗中不同饵料的饲养效果比较

培育双壳类软体动物幼苗所需的饵料，是指池内培育阶段适合于幼虫和幼苗(壳长一般在1mm以下)的饵料。育苗成功的关键问题之一为是否已经选择到这样的饵料。自40年代找到适宜的饵料生物以后，双壳类幼虫的培养才取得较明显的成效。以往利用过的一些饵料生物巳有文献系统记载。我国贻贝人工育苗是在分离与培养出扁藻以后才获得成功的。随着研究工作的深入以及适应各种不同情况的需要，采用的饵料种类越来越多样化。从生产性育苗特别是多茬育苗考虑，必须因地制宜地筛选出一定种数的饵料，以便在不同培养条件下有机动选择的余地。同一时还应找出适宜的投饵数量，以求取得较好的育苗效果。为此目的，我们于1975-1978年结合生产性育苗的需要进行了一些饵料饲养实验。本文根据实验结果以及多年来生产性育苗的实践，对贻贝育苗的饵料问题进行总结，侧重于不同饵料的饲养效果比较。     

Current status of bacteriological parameters and DOC/POC in Xiamen coastal waters

The surface and bottom waters samples were collected from six locations in Xiamen western sea. The quantified estimation of bacterial production (3H-thymidine method) and observation of bacterial heterotrophic activity (14C-glucose method) have been made in order to have a better understanding of the role of marine bacteria and their activities. The results showed that the mean value of bacterial heterotrophic activity was 9×108 cells/(L.h) in the surface waters and 2.6×108 cells/(L.h) in the bottom waters. The mean value of bacterial production was 38×108 cells/(L.h) in the surface waters and 7.1×108 cells/(L.h) in the bottom waters. The relationship between bacterial production, heterotrophic activity, POC and DOC measured during this survey were discussed. The good understanding of the relationship between bacteria activity and total coliform was addressed.     

Test Study on Current Force on Mooring Ships

In respect of an offshore berthing pillar, the test study result of current force acting on mooring ships is described in this paper. Empirical and semi-empirical relationships of current force coefficient are given according to the angle between the flow direction and the ship's longitudinal axis, which are coincident with the result of theoretical analysis.
