藻类的

When algae bloom, they can discolor the water as they form dense areas near the surface.

当藻类爆繁时，它们能改变水的颜色，这是藻类在接近水面的地方稠密聚集造成的。

Microalgal technology is a developing technology built on phycology, phytoplankton ecology and aquatic ecosystem Generally, it focused on taking full advantage of physiological and ecological characters of phytoplankton, and then, built up a systemic technology for control and optimization on ecology system of aquatic environment.

微藻技术是一项有机结合藻类生物学、藻类生态学及水生生态系统学的新兴生物技术，它以水体中的浮游微藻为对象，充分运用微藻的生理、生态特点，进而用以调控和优化水体生态环境。

During the growth season in the year 1998—2000, through collecting、culturing and identifing the subaerial algae which is in 26 research sites of forest and 11 communities of steppe vegetation, there are 107 species of subaerial algae in Jilin's terrestrial ecosystem which are subordinated to 12 families, 29 genus in Cyanophyta.

在1998—2000年三个生长季节内，通过对设立在森林区内26块研究样地及草原植被带内多状态下的11种群落类型中的亚气生藻类标本采集、培养、鉴定，中国东北森林-草原样带中共有亚气生藻类107种，隶属于蓝藻门、绿藻门及黄藻门的12科29属。

Closed-system algal toxicity test was applied to evaluate the toxicity of secondary and tertiary propargylic alcohols to Pseudokirchneriella subcapitata. The effects of propargylic alcohols were evaluated by three kinds of response endpoints, i.e., dissolved oxygen production, cell density, algal growth rate.

bstract：本研究以藻类（Pseudokirchneriella subcapitata）利用BOD瓶进行一密闭式系统之毒性试验，使用溶氧变化量，藻细胞的数量变化，以及以藻类细胞密度变化量计算所得的生长率三个终点，评估二级以及三级炔丙基醇类之毒性，藉由Probit模式求出半致死浓度（50% Effect concentration，EC50）。

Periphyton are all organisms growing on solid substrata and have important contributions in primary production in shallow coastal ecosystems.

附生藻类是著生於固态基质上一切生物的集合群体，附生藻类在浅水域生态系中因高生产力有著重要的贡献与角色。

Research shows that algae from open water body are greatly trapped in the macrophyte-covered littoral zone ,and decomposed there.

研究发现植被型岸边带可以大量捕获来自开阔水体的漂浮藻类，并使之在岸边区迅速降解，从而减少了进入水厂的藻类生物量。

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。

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。

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。

Fancy gold-plated dangling earrings with facetted White Opal crystals.
