藻类

Algae are common on "slimy" rocks in streams and as green sheens on pools and ponds.

利用藻类的历史或许与人类的历史一样悠久，沿海的居民食用海藻，许多餐馆里都提供藻类食品。

Our field research was the first time to compare the biomass and production of phytoplankton and periphyton before and after the removal of oyster-culture pens at a scale of whole lagoon.

本研究是第一篇藉由大尺度牡蛎养殖移除的野外实验，比较有、无牡蛎养殖对於浮游藻类及附生藻类生物量及生产力的差异。

In order to reveal the effects of tilapia on phytoplankton and periphyton, an experiment with two treatments, one with tilapia and one without tilapia (non-fish group) was carried out, and the biomass of both phytoplankton and periphyton was analyzed.

为了解罗非鱼对浮游植物和附着藻类的影响，实验在室外模拟条件下，分别设置罗非鱼组和无鱼对照组的两组处理，分析了罗非鱼对附着藻类及浮游植物生物量等的影响。

4Both filamentous periphyton and unicellular periphyton showed significant effects on TSS and Chla removal and increase of DO concentration.

4无论是丝状周丛藻类还是颗粒态周丛藻类，均表现出对TSS、Chla的去除效果和对DO浓度的提高。

This paper has studied the removal of nitrogen and phosphorus in polluted urban waters by filamentous periphyton and unicellular periphyton through designing a simple wastewater treatment system,under the near-natural conditions.

本文通过设置简易的水质处理系统，在近自然条件下，分别研究了丝状周丛藻类和颗粒态周丛藻类对上海市劣Ⅴ类黑臭水体氮、磷的去除效果。

6Unicellular periphyton has also shown good adaptability to sewages,with remarkable increases of Chla(58.2%)and biomass (54.0%).It was also observed that community compositions were successfully changed from original unicellular Bacillariophytes and chlorophytes dominated community to filamentous and unicellular Cyanobacteria dominated community.

6水质处理期间，颗粒态周丛藻类也表现出对污水环境很好的适应性，其Chla在整个试验期间增长了58.2%，生物量增长了54.0%，群落组成由试验初期的颗粒态硅藻、绿藻为主，转变为试验后期的以丝状和颗粒态蓝藻、绿藻为主的藻群，水绵、丝藻、纤维藻、颤藻等藻类大量出现。

Also it influenced the growth of algae and the living of shrimps at level of 0.033 mg/L, but no significant toxic effects on other zooplankton such as Daphnia magma, ostracods, rotifers and so on was detected.

结果表明，莠去津浓度为0.023 mg/L时对藻类生长会产生影响；浓度为0.033 mg/L时对藻类生长和河虾生存均会产生影响，但对其他浮游动物，如大型溞、介虫、轮虫等未产生显著的毒性效应。

From results, we can presume that UV-B enhancement may be one of factors, which cause red tide.

另外这三种藻类分泌到细胞外的物质的紫外吸收情况对于不同藻类有所不同。

In addition, as important indicators of water quality, COD was effectively controlled and SD increased remarkably.

在有机肥实验中，生物水净化剂对藻类有明显的抑制作用，浓度越高，对藻类的抑制作用越明显。

Various effects imposed by tracemetal nutrient on red tide algae might bring changes of dominant species.

微量金属元素对赤潮藻类影响的不同可能改变水体中赤潮藻类的优势种群。

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。
