1·Certain species of phytoplankton produce powerful biotoxins, making them responsible for so-called "red tides," or harmful algal blooms.
某些种类的浮游植物会产生强大的生物毒素，它们会形成所谓的“赤潮”，也叫做有害藻华。
2·As a secondary metabolite, the synthesis of algal toxin may be considered as an inhibition or rejection response to other phytoplanktons in the competition among communities and species.
作为次级代谢产物，藻毒素的产生可能是一种压制或清除其它藻类竞争者的一种反应，在群落演替、种间竞争中发挥重要作用。
3·The formation of algal limestone reservoirs has mainly been controlled by the stability of sedimentary environment, early eluviation and late cementation filling.
藻灰岩储层的形成主要受沉积环境的稳定性、早期淋溶和晚期胶结-充填作用的控制。
4·Tertiary algal (cyanobacteria) limestones reservoirs in the western Qaidam basin are characterized by widespread distribution and being the most important in the carbonate reservoirs.
柴达木盆地第三系藻(蓝细菌)灰岩储层分布较广，是柴达木盆地第三系碳酸盐岩储层中最重要的油气储层。
5·Distributed in extensive areas, Tertiary algal limestone reservoirs in Qaidam basin are the most important oil and gas reservoirs in the Tertiary carbonate rock reservoirs in the basin.
柴达木盆地第三系藻灰岩储层分布较广，是柴达木盆地第三系碳酸盐岩储层中最重要的油气储层。
1·Sewage nutrients do increase algal growth in the harbour.
污水中的营养物的确会加快海藻的生长速度。

2·Viewing the salamanders under a fluorescent microscope, the researchers were able to see the algal pigments "shine" when they were illuminated with light of a certain wavelength.
采用荧光显微镜对火蜥蜴进行观察，研究人员能够看到海藻色素“发光”当它们被一定波长的光照射的时候。
3·It takes roughly a pound and a half of dried, pressed algae to make a pound of the algal portion of the plastic, he says.
他说，通常一磅半左右干的经过压制的海藻可以获取一磅的用来制取塑料的海藻。
4·These cause the algal cells to expel the oil almost as soon as they have manufactured it.
这使得海藻细胞可以在制造出油料的同时便迅速排出。
5·Increasingly, though, swimmers, sailors and even those who monitor the sea with the help of satellites are encountering highly visible algal blooms known as red tides.
然而，由于海藻爆发生殖产生的赤潮现象，发生次数却越来越多，这是游泳者、水手、甚至是通过卫星检测海域的人有目共睹的。
