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     

云贵高原湖泊沉积物─水界面碱度扩散通量研究

于１９９１－１９９５年间５次在云贵高原泸沽湖，洱海湖和贵州阿哈湖，百花湖的湖心采集沉积物柱芯，界面水和湖水样品，通过其ｐＨ值和ＨＣＯ３浓度剖面及界面碱度扩散通量的研究，首次定量评估高原湖泊界面扩散作用上不体碱度的影响程度，研究结果表明，云贵高原某些湖水寄宿时间对较长，湖水深度相对小的湖泊，界面扩散作用是水体碱度的重要来源之一，湖水寄宿时间较短，深度较小的湖泊，界面扩散对上覆水体的影响可以忽略不地。     

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     

LARGE-SCALE CIRCULATION CONDITIONS AFFECTING THE HURRICANE FORMATION OVER THE NORTH ATLANTIC OCEAN

A contrasting study of the large-scale circulation features responsible for months or seasons with many hurricanes and those with few hurricanes has revealed that the frequency of hurricane formation over the North Atlantic Ocean is enhanced by the following conditions:There exists a well-developed subtropical high-pressure belt displaced to the north; a deep Icelandic low; a stronger-than-normal polar vortex with a deep polar trough dipping far southward along the eastern part of the United States; a dominant high-pressure ridge over western Canada and the United States; and a jet stream displaced northward over these regions. At 200 hPa, an anomalous anticyclonic circulation prevails over the subtropical North Atlantic. A stronger-than-normal upper easterly flow prevails. Positive sea surface temperature anomalies prevailing on a seasonal or long-term basis tend to be favorable for the formation of hurricanes.     

SOLID-LIQUID INTERFACE PROCESS OF HEAVY METALS IN THE CHANGJIANG ESTUARYKINETICS OF ADSORPTION OF Pb, Cu AND Cd ON HFO

The adsorption kinetics of Pb, Cu and Cd on hydrous ferrk oxide (HFO) has been approached in tthe simulated environmental conditions of the Changjiang Estuary. The forward adsorption rate constants of different systems under different temperatures have been determined, and the activation energies of the adsorption for Pb and Cu evaluated (Pb=7 kcal/mol, Cu= 11 kcal/mol). The results show that Pb and Cu are strongly adsorbed by HFO; the order of their adsorption rate is found to be Pb≥Cu≥Cd, which follows thte order of their theonody-namic equilibrium constants. It has been demonstrated that the surface exchange-adsorption is the determining step of the solid-liquid interface process. The field investigation results are theoretically explained by the kinetic mechanism.     

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.
