一个南海热带气旋发展的环流特征分析

本文用ECMWF2.5×2.5网格点资料通过一个例子,对有利于南海热带气旋发展的环流场作了详细的分析,发现几点事实:(1)扰动在风的垂直切变较大的环境中仍可发展。(2)扰动位于中、低空西南急流左侧,高空南支东风急流右侧时,有利发展。(3)中,低空西南急流形成了扰动环流的强风潮,强风潮从扰动南侧入角,并包围扰动的东半圆。(4)扰动中、低层的入流和高层的外流呈现严重的不对称性。(5)当扰动发展到一定强度时,对南海热带季风环流圈的加强起到正反馈作用。     

中国沿海星虫动物门名录

取1980～1989年间在我国沿海进行星虫动物区系调查的标本和有关资料做了整理、鉴定,共39种,分隶于2纲,4目,6科,12属。其中1种在我国为首次记录。     

西沙群岛附近海域羽纹硅藻分类研究 Ⅰ

继“西沙、中沙群岛附近海域浮游硅藻类分类的研究”之后,作者又对西沙群岛所属岛、礁附近海域的羽纹硅藻进行了初步整理,共鉴定出羽纹硅藻11属27种及其变种(其中8种是我国首次记录)。本文对首次记录的种类进行了比较详细的说明和绘图。某些在我国其他海域已有报道的种类,如光辉针杆藻、串珠梯楔形藻、海生斑条藻、琴状舟形藻、流苏胸隔藻、双标胸隔藻、钝端双眉藻、细纹斜盘藻等,以往的描述较简单,并且与西沙群岛标本的形态也不完全雷同,为了便于应用和比较,本文根据西沙群岛的标本,又进行了较详细的描述或补充说明。对有图而无说明,或仅有名录的种类的国内资料,在地理分布内注明。为了保持西沙群岛所属海城硅藻分类研究的连续性,本文仍采用 Hendey 提出的分类系统排列。 为便于读者査找,每一种名下列出其同物异名。 标本多用小型浮游生物网采得,有些则取自珊瑚表面。插图均用描图仪描绘。     

钛型吸附剂的表面特性

用自装的BET容量法装置测定了几种粒状钛型吸附剂的比表面及其孔径分布。测定是在常温减压下进行的。结果表明:钛型吸附剂在加铀海水中的吸铀量与样品的比表面及孔径分布有一定的内在联系。这种表面性质的研究对吸附剂的筛选有重要的指导意义。     

The behaviour of 59Fe in marine microhabitat

Under the artificial condition the 59Fe morphology in sea water, its concentration in sediment and phytoplankton, its distribution and metabolism in tissue organs of marine animals were studied. The results showed that the morphology of 59Fe was in a particulate state in sea water. The adsorption rule of 59Fe by three kinds of sediments was similar. The concentration ability of 59Fe by phytoplankton was very strong. The critical concentration organs of S9Fe by marine animals were viscera. The gross radioactivity of 59Fe was mainly concentrated in protein. The concentration factor of 59Fe by DNA was the highest one. After excretion experiment, 59Fe of all the tissue organs was not detected. Small part of59Fe remained in the organic acid and protein state. There was a redistribution process in sediment for59Fe.     

几种养殖鲍同工酶生化遗传的比较研究

运用聚丙烯酰胺凝胶电泳对我国主要养殖鲍(皱纹盘鲍、盘鲍及九孔鲍)12种同工酶(LDH、ME、MDH、GPI、PGM、IDH、IDDH、SOD、EST、ODH、ADH、AAT)26个基因座位进行了分析．结果表明：EST、PGM可以作为区分三种(亚种)鲍的生化遗传标记；在所分析的位点中，未发现多态现象，表明三种养殖鲍杂合子缺失严重，其主要原因可能在于哑基因、近交与自然选择。     

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.     

中国鱼类学会第四次全国代表大会暨1993年学术年会在青岛召开

随着人类活动的频率不断加强，高额掠捕重要经济鱼类资源、环境污染直接威胁鱼类生态栖息地、人工增养殖培苗系统对天然鱼种遗传多样性的破坏等，已在相当程度上导致物种绝灭、传统鱼种资源衰退和种质资源的退化。因此，尽快查明我国鱼类物种多样性特征，研究持续利用重要鱼类资源和开展濒危鱼种的保护生物学研究，已成为当今鱼类学研究的优先主题，更需委我国鱼类学研究工作者的共同努力。本着这一热衷愿望，中国鱼类学会第四次全国代表大会暨1993年学术年会，于1993年10月25日-30日在青岛召开。这次会议得到了全国鱼类学界的积极响应，应…
