藻类

While in summer, phytoplankton becomes the main effect factor of spectrum absorption in water.

而夏季由于浮游藻类含量较高，使其成为水下光谱的主要影响因素。

In spring and autumn, non-algal particles were the predominant spectrum absorption factor in water, because the concentration of inorganic matter is higher than organic matters in the two seasons.

春、秋季由于无机悬浮物含量较高，非藻类颗粒物对总吸收的贡献大于其他组分，是水体总吸收的主导因子。

In this paper,effect of acetanilide herbicides butachlor on Phsiological and Biochemical Characteristics of Microalgae Dunaliella salina was studied in the laboratory.

在海洋生态系统中，海洋微藻起着十分重要的作用。藻类不仅对毒物敏感，而且具有易获取、个体小、繁殖快的特点，是一类很好的测试生物。

Currently, the impact of excessive phosphorus on water bodies focuses on eutrophication and algae overrun, which have been the hotspots and intractable problems for environment protection in China, essentially an outcome of the concentration of the compounds of nitrogen and phosphorus, and the heavy reproduction of aerobe.

当前过量磷对水体产生的影响集中地表现为富营养化和藻类繁生现象，其实质是耗氧有机物及氮、磷化合物的生态环境效应。它们已成为我国环境保护的热点甚至是十分棘手的控制治理问题。

The result showed that Limnanthemun nymphoides can apparently decrease the concentrations of total nitrogen and total phosphorus in overlying water, control the growth of agal and improve water quality.

结果表明，在培养实验过程中，荇菜生长使上覆水体中的氮、磷营养水平逐渐降低，藻类的生长明显受到克制，水体透明度增加，水质逐渐改善。

In the fishpond ecosystem, heavy metals moved and transformed by a complicated process such as aggradation, release, accumulation and excretion.

由底泥、水体、藻类和鱼类组成的鱼塘生态系统中，重金属可通过沉积、释放、积累、排泄等复杂过程构成其在生态系统内的迁移转化。

Although there is 34,500 tons of gaseous nitrogen in the air column above each acre of the earth's surface, this cannot be used by plants until it has been fixed by nitrogen-fixing bacteria and algae.

虽然在地球表面每英亩空气柱中有34，500吨气态氮，但是如果这些气态氮不被固氮菌和藻类固定，是不能被植物利用的。

Simple organisms such as bacteria and alga have been found fossil in rocks more than 3000 m.

简单的生物，如细菌和藻类，它们的化石已在三十多亿年的岩石中发现。

AQUASHADE gives water an unpleasant green algae appearance, while CLEAN-FLO LochNess Pond Dye gives pond algae control and aquatic plant control by producing a beautiful dark Loch Ness Lake color while hiding submerged trash from view.

AQUASHADE使池塘的水显示令人厌恶的绿色藻类的外观，而CLEAN-FLO的尼斯湖水色染色剂，带给您的池塘卓越的藻类和水生植物控制，使您的池塘呈现美丽的黑尼斯湖的颜色，同时从视线中隐藏垃圾。

The light quantum yield of algae particles is one of the important parameters characterizing the algae response to the environmental factors.

藻类光量子产额是表征藻类对环境因素响应的重要参数之一。

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。
