For research of bivalve's effect on marine plankton community structure, we conducted Aug.—Dec. 1996 experiment to study the two bivalves' feeding selectivity and their filter－feeding rates. For observing the feeding selectivity, Chlorella sp., Chaetoceros muelleri, Lermmerman, Nitzschia closterium and Pyramidomonas sp.

于1996年8—12月，分别从青岛海洋大学太平角实验基地和胶南市水产养殖研究所采集海湾扇贝和太平洋牡蛎，采用室内实验的方法，比较研究了不同规格的两种贝类对4种不同大小藻类的选择性及水温对其滤除率的影响。

The productivity of Eustigmatophytes and coccolithophorid calculated by the concentrations of 〓 diol and long-chain ketones, respectively, indicate that the paleoceanographic environment and paleoclimate were unstable in Nansha area during the last glacial. The productivity of the two algae fluctuated greatly and was higher during the glacial than that in Holocene.

由〓烷基二醇和长链不饱和酮含量分别计算出的黄绿藻、颗石藻古生产力揭示出南沙海区末次冰期的古海洋环境及古气候是不稳定的，两类浮游藻类的生产力在冰期都出现了较大的波动：黄绿藻、颗石藻的生产力在末次冰期都比全新世高，特别是在H3时都出现了生产力增大的事件。

顺势疗法准备，特别是，一种含藻类的药，咖啡因，天然海盐和甲状腺激素。

Furthermore, according to the summing-up of water treatment for the Chaohu Lake, the measures, such as pre-oxidation to water source-polymeric aluminum-ferric and ferrous surplus chlorine coagulation- HCA concretional aid-cl.

文章对巢湖微污染水质的特点及形成原因进行了深入的研究；对氨氮、藻类、p H值、异味等四个特征指标的变化规律做了详细论述；对以巢湖为水源的水处理技术进行了总结，提出了源水预氧化—聚合铝铁、亚铁氯化联合混凝— HCA 助凝—除臭剂、活性碳联用去除异味—微絮凝的高效率水处理模式，不仅在合肥供水集团有限公司取得了非常良好的应用效果，也可为其它以内陆湖泊为水源的制水厂所借鉴。

It is shown from the assessment results that (1) both the TN and TP fluxes discharged from the Changjiang River to the Changjiang River estuary sea area increased continuedly, the DIN concentration in the sea areas increased continuedly, and the Si concentration decreased continuedly, which resulted in the significant changes in N/P/Si ratios;(2) the chlorophyll a concentration in the sea areas increased continuedly, and the significant changes in community structure of phytoplankton occurred;(3) the species and biomass of benthos declined greatly, and the bottom oxygen-poor water area increased significantly;(4) the range and occurrence frequency of red tide events in the sea areas increased greatly, and the algal toxic infection events of mussel were frequently found in the sea areas.

结果表明，长江向长江口海域输送总氮和总磷通量持续增大，长江口及其邻近海域无机氮浓度持续增高而硅浓度持续下降，并由此导致N/P/Si与比值的显著变化；该海域叶绿素a浓度持续增大，浮游植物群落结构也发生了显著变化；该海域底栖生物种类和生物量都大大减少，底层水低氧区面积也显著扩大；该海域赤潮事件无论是规模还是频率都大大增加，藻类毒素DSP/PSP贻贝传染事件也时有发生。

Manchurica, Eugonophyllum, cyanophyceae community and another is Formit-chevella community.

manchurica，叶状藻Eugonophyllum和菌藻类蓝细菌群落及珊瑚Formitchevella群落。

In March, May and July, Cyanophyta was the dominant one, with high proportions of 45.6%, 55.9% and 87.7%, respectively, whereas the proportions for Bacillariophyta decreased to 30.1%, 25.9%, and 1.1%, respectively. In November, proportions for Bacillariophyta and Chlorophyta were equivalent, 40% each, and the Cyanophyta composed below 20%. In December, Bacillariophyta made up 25.6% and Cyanophyta 38.2%. In March, May and July, dominant species of Cyanophyta were Microcystis aeruginosa, Pseudoanabaena, and Gloeothece linearis. In dry January, November and December, species of Bacillariophyta were dominated by A chnanthes sp., Melosira ambigua, Melosira granulata and Cyclotella meneghiniana.

全年中，蓝藻与硅藻比例变化较大，二者呈相反的变化趋势。1月份硅藻占较高比例（63.1％），蓝藻较低（〈20％）；3、5、7月份蓝藻比例较高（分别为45.6％、55.9％、87.7％），而硅藻较低（30.1％、25.9％、1.1％）；11月份硅藻与绿藻比例相当（各占40％），蓝藻低于20％；12月份硅藻与蓝藻比例分别为25.6％与38.2％。3月份和丰水期浮游植物优势种主要为铜绿微囊藻、假鱼腥藻和线形粘杆藻等蓝藻种类，枯水期的1月、11月和12月主要以曲壳藻类、模糊直链藻、颗粒直链藻和梅尼小环藻等硅藻种类为优势种。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
