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.     

均匀水底上二维随机波面的二阶谱

本文用摄动方法导出了均匀水底上精确至二阶的二维随机波动解。依据此解并将二阶谱定义为三阶矩函数的Fourier变换,首次给出了精确至二阶的二维随机波面二阶谱的理论表达式并简略地考虑了它的各个组成部分的物理意义。     

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。     

FINITE ELEMENT METHOD IN CALCULATION OF KUROSHIO CURRENT

We establish the equations of finite element approximation for three-dimensional ocean current and calculate the Kuroshio current in the eastern sea area off Taiwan Province. The interpolation error of finite element approximation is given as Eq. (3. 14).     

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.

西太平洋暖池变异及其对西太平洋次表层海温场的影响

应用热带太平洋上层XBT温度资料,分析研究了西太平洋暖池区(0°～16°N,125°～145°E)上层海洋的变化特征以及与西太平洋次表层海温场之间的关系.研究表明,西太平洋暖池区的垂向温度存在显著的年际变化,尤其在次表层(120～200m)的变化最为明显.西太平洋暖池区的次表层冷暖信号明显早于西太平洋次表层的海温异常.分析发现,西太平洋暖池区的海温异常是导致整个西太平洋次表层海温场变异的关键区,当西太平洋暖池区的次表层冷暖信号加强时,3～4个月后西太平洋海温场出现大范围的冷暖异常.
