黄河三角洲桩西101站潮沟地貌形态及其水动力学研究

在潮沟下游，横跨且生趣与潮沟的横断面设了５个观测站，进行了２４ｈ的水动力测量。结果表明，涨落潮流速流向不对称，在潮沟内，涨落潮流流速差别很大，涨潮流流速最大为９ｃｍ／２，而落潮流流速最大可达３８ｃｍ／ｓ。据推测，潮沟内之所以落潮流流速明显大于涨潮流流速，可能是由于潮沟与岸线斜交有关。

春季东海不同水域的表层叶绿素含量

利用１９９４年春季在东海及台湾海峡首次获得的表层水中绿素含量大面走航连续观测资料，结合温盐分布及以往的有关东海及台湾海峡的海流和上升流的结论，分析了春季东海表层叶绿素含量在不同水域的分布特征。结果表明，叶绿素含量分布与水文结构关系密切。叶绿素含量值随不同海流流域而变，但在各海流流域内基本不变，黑潮表层水的叶绿素含量最低，其次是台湾暖流表层水，长江冲淡水与江浙沿岸流域的叶绿素含量较高；黑潮西侧弱流剧     

An infinity of conservation laws of fKdV equation

An infinity of conservation laws of fKdV equation is derived in terms of the Miura and Gardner''s transform.The pseudo-mass and energy theorems are studied by the first two conservation laws.As a typical example,the theoretical mean wave resistance and the regional distribution of energy of the precursor soliton generation are determined by means of the first and the second conservation laws.

春季东海表层水叶绿素a含量分布特征

依据“科学一号”调查船１９９４年４月在东海１０个断面上所进行的表层水连续走航观测资料，研究东海表层水叶绿素α含量在不同空间尺度上的分布特征和变化规律。结果表明，叶绿素α含量在陆架区高，在外海低；测区南部海域的含量一般高于北部海域。叶绿素α含量的分布形态变化很大，在某些外海深水区，叶绿素α含量连续百科公里没有显著变化，变化幅度小于０．２ｍｇ‘ｍ＾３；而在某些近海浅水区，叶绿素α含量在不到１公里范围内     

Morphology, reproduction, ecology and isoenzyme electrophoresis of Capitella complex in Qingdao

-Morphology, reproduction, ecology and isoenzyme electrophoresis of a Capitella complex in Qingdao were examined from 1983 to 1984. We determined that the Capitella complex in Qingdao was composed of at least three sibling species: Capitella cf capitata, Capitella sp. I and Capitella sp. IT. Although these three species are very similar in morphology, they differ in: three kinds of isoenzyme electrophoresis, staining reactions, developmental pattern, larval morphology and dispersal, reproductive strategies, breeding season and population ecology. In addition, they show a series of minor quantitative variations in adult morphology, especially in number and morphology of setae. Such differences can be detected only at the population level. Some ecological data such as density, growth rate, mortality and sex distribution are also provided in this paper.     

Experiments in numerical modelling of the Pacific sea surface temperature anomalies

By using the atmosphere-ocean coupled model (CGCM) which is composed of a 2-level global atmospheric general circulation model and a 4-layer Pacific oceanic general circulation model developed in the Institute of Atmospheric Physics of Chinese Academy of Sciences, and two model climatological fields got from the two independent models' numerical integrations respectively, the Pacific sea surface temperature anomalies (SSTA) from 1988 to 1989 are simulated in this paper with observed atmospheric general circulation data and sea surface temperature fields as initial conditions and monthly coupling scheme. In order to remove systematic biases of the model climatological fields, interaction variables between atmosphere and ocean are also corrected simultaneously. The experiments show that the simulation results can be improved effectively if these interaction variables are corrected in spite of the fact that there always exist systematic biases in independent numerical simulations of atmospheric part and oc     

大黄鱼(Pseudosciaena crocea)转铁蛋白(Tf)基因克隆及序列分析

提要应用RNeasy animal mini试剂盒抽提大黄鱼total RNA,逆转录合成模板cDNA;同时综合分析从GenBank数据库查询到已报道的转铁蛋白(Tf)基因序列,先设计并合成扩增引物扩增出大黄鱼转铁蛋白部分基因序列,再应用RACE技术,克隆出大黄鱼转铁蛋白全长cDNA基因,全长2461个核苷酸,编码661个氨基酸。应用WCG软件包,采用DNADIST和NEIGHBOR分析方法,构建了转铁蛋白系统进化树。树图显示与传统的分类地位大致相符,可以看出转铁蛋白在海水鱼和淡水鱼的进化上的差异,同时也显示大黄鱼Tf与真鲷的同源性最高。
