温度、光强和盐度对鹧鸽菜幼体生长发育的影响

从野外采集鹤鸪菜Ｃａｌｏｇｌｏｓｓａｌｅｐｒｉｅｕｒｉｉ（Ｍｏｎｔ．）Ｊ．Ａｇ．幼体，在室内控制条件下，以温、盐、光等不同条件进行模拟培养试验。所获得的数据经生物统计检验表明：鹧鸪菜幼体生长最适水温为２３℃；光照强度为４０００ｌｘ；海水盐度为１８。此结果与我们多年来在汕头港内观察鹧鸪菜的生长及其季节变化相似。     

大气污染物质SO2对雾水酸度的控制作用

主要研究了青岛大气污染物质ＳＯ２对雾水酸度的控制作用，用实测结果统计得到雾得水ＰＨ值与Ｃｓｏ２的经验关系式，青岛、烟台等地雾水ｐＨ值与计算值吻合一致，表明统计关系的合理性。通过对青岛雾水中ＳＯ２清除率的估算，说明在青岛雾期，人为污染物质所占比值越高，其污染物质沉降百分率也越高，存留在大气雾中百分率就愈低。     

青岛局地风特征的分析

本文根据位于胶州湾东岸的青岛沧口和流亭两机场气象台和唠山区气象台资料及现场实验资料对胶州湾东岸的海陆风气候特征,来自胶州湾与来自南面黄海水域的两支海陆风相互作用及其对沧口地区的影响,崂山西坡下坡风的气候特征及影响进行了分析。文中还提出了一种根据常规气象观测资料估算海陆风发生频率的方法。     

Observations of the countercurrent on the inshore side of the Kuroshio northeast of Taiwan

Intensive current measurements in the area northeast of Taiwan indicate subsurface, southwestward flow existed between the inshore edge of the Kuroshio and the East China Sea continental slope. At 70 km away from Taiwan, this countercurrent has a mean speed about 30 cm s^–1 at mid-depth. Closer to Taiwan, the flow turns along with the topography, and subjects to sidewall and bottom friction. Both the magnitude and the vertical shear of this countercurrent are comparable with that inferred from hydrographic survey. The wind field features short-period (a few days) fluctuations associated with the cold front passages, however, this is not reflected on the current records. It appears that the countercurrent is fairly steady. Together with similar reversing flow found at places much further to the north, the overall pattern seems to be a general quasi-steady feature along most part of the shelf edge of the East China Sea.     

Cross thermocline mixing effect due to tide in the shallow sea

Using the data specially observed on the Bohai Sea oil platform by the authors for studying thermocline for two weeks, the thermocline depth, the temperature and the salinity of the layers below and above the thermocline were numerically modelled. The model is based on the Stigebrandt model and some important supplements are made in this paper in accordance with the local condition of the sea. The modelling results fit well in the observations. It is proved that the entrainmem due to both the tide and the wind can give rise to rather intense mixing cross the thermocline. This process makes the temperature rising below the thermocline,and causes the nutrient increasing above it,which has important significance for the marine physical environment and the marine organism.     

南海中北部表层沉积物的矿物沉积

本文研究了南海中北部500多个样品的矿物学。认为,本区表层沉积物中矿物种类繁多,分布较为普遍,碎屑矿物(含火山物质)、粘土矿物、自生矿物常有出现。以前者为最显著(共60多种,其中重矿物50多种,轻矿物近10种),主要分布于陆架区及深海盆;粘土矿物次之,多分布于陆坡～深海盆;自生矿物较少,陆架～深海盆均有分布。文中根据矿物沉积特征和环境差异,把它划分为6个矿物区。     

用纤维素乙酸平板电泳测定中国卤虫的同功酶变异(英文)

本文报导了应用纤维素乙酸平板电泳方法,测定采于中国山东省东方红盐场卤虫(Artemia)的同功酶。经测定,8种同功酶其中有6种是多态的,即:苹果酸脱氢酶(MDH)、异柠檬酸酶(IDH)、谷氨酸草醋酸转移酶(GOT)、葡糖-6-磷酸盐脱氢酶(D6PHD)、6-磷酸萄糖脱氢酶(6PGDH)和磷酸葡糖异构酶(PGI)。本文所提供的研究方法,不仅适用于基础研究,而且在水产养殖业上有助于对卤虫的筛选和确证。
