Using culture medium selection, diluted separation, plate lineration, centrifugal separation, capillary separation, droplet separation, pH separation, temperature separation, inhibitor separation and so on, ten species were obtained. There were Cyanophyta Nostoc punctiforme, Phormidium tenue, an undetermined alga; Chrysophyta Chromulina ovalis; Chlorophyta Cholorella ellipsoidea, Scenedesmus bijuga, S. quadricauda, Elakatothrix sp., Selenastrum minutum and Bacillariophyta Navicula sp.

采用培养基筛选法、稀释分离法、平板划线分离法、离心分离法、毛细管分离法、小滴分离法、pH值分离法、温度分离法、抑制剂分离法等9种不同方法，最终分离纯化出4门9属10种藻类，其中包括蓝藻门念珠藻属的点形念珠藻、席藻属的小席藻和一未定种；金藻门单鞭金藻属的卵形单鞭金藻；绿藻门小球藻属的椭圆小球藻、栅藻属的双对栅藻和四尾栅藻、纺锤藻属的一种、月牙藻属的小形月牙藻和硅藻门的舟形藻属的一种。

The sequence of rDNA Intergenic Spacer Regionwas determined for the species Oscillatoria sp.. The spacer sequences was 427bp in lengh exclusive of 16S and 23S rDNA coding regions,containing a Ile tRNA gene.

采用末端终止法对蓝藻类颤藻科Oscilatoriasp.rDNA16S－23S基因间隔区进行了序列测定，获得了Oscilatoriasp.rDNA基因间隔区427个核苷酸，其中包含1个异亮氨酸tRNA基因。

It was shown that there are 226 species,105 genera and 9 phyla of algae in the reserve and they are composed of Bacillariophyta,Chlorophyta and Cyanophyta in the majority and Phaeophyta,Pyrrophyta,Xanthophyta...

怀九河源头的物种丰度和硅藻多度均最大，洞台、黄坎丝状蓝藻占优势，怀柔水库绿藻占优势；在时间分布上，7月物种丰度和藻类多度最大。

In order to disclosure the formation rule of predominant species in different nutrition conditions,three kinds of nutrition concentration were selected for the competition experiments with the common species of blue-green algae bloom Microcystis aeruginosa and the common species of green algae bloom Scenedesmus quadricauda .

为了揭示不同营养条件下，藻类优势种的形成规律，选取了3种具有代表性水体的营养盐浓度，对于蓝藻水华的常见种铜绿微囊藻和绿藻水华的常见种四尾栅藻进行了竞争实验。

The study of taxology and ecology of sub-aerial blue-green algae of Neimenggu was comparatively deficient in the past. As a result, my research will supply datatostudy the particular function of sub-aerial blue-green in terrestrial ecosystem.

目前国内学者对内蒙古亚气生蓝藻的分类及生态研究较少，因此这一课题有其特殊的理论价值和应用前景，为进一步探讨亚气生藻类在陆地生态系统中的详细功能提供了本底资料。

Objective To investigate the contaminative condition of planktonic algae,cyanobacteria,toxigenic microcystis and microcystin in Huayuankou Conservation Pool of Yellow River.

目的了解黄河花园口某调蓄池浮游藻类、蓝藻、产毒微囊藻和微囊藻毒素污染情况。

According to concerning chief introduction, at present blue green alga of domestic and international processing basically has put in chemical reagents, machinery to catch, biology pulls alga, shading to be divided except alga, electrochemistry alga, artificial wait for measure wetly except alga.

据有关负责人介绍，目前国内外治理蓝藻主要有投放化学试剂、机械捕捞、生物拉藻、遮光除藻、电化学除藻、人工湿地除藻等办法。

At the heart of The Lifting Face Serum is a rare blue algae that flourishes in pristine waters fed by ancient glacial waters and underground springs.

面部提升血清是一种罕见的蓝藻是蓬勃发展的原始水域靠古老的冰川水和地下泉水。

When the algae die (or are eaten and egested by zooplankton), they decompose on the bottom, depleting the oxygen, suffocating sea life and hurting livelihoods.

当蓝藻死亡后（或是被浮游生物吃掉排出），他们在河底部腐烂分解，消耗氧气，导致海洋生物窒息死亡，还会伤害到生态环境。
