裸藻

Analyses by RAPD and 18S rRNA sequence both support that A. longa is closely related to Euglena gracilis.

RAPD和18S rRNA序列分析结果都显示长变胞藻和纤细裸藻有着密切的亲缘关系。

Its location varies. In Chlamydomonas it is just inside the chloroplast; in Euglena it is near the base of the flagellum.

眼点的位置各不相同，在衣藻中，它位于叶绿体内，在裸藻中眼点临近鞭毛基部。

The phytoplankton community was mainly composed of Cyanophyceae, Euglenophyceae, Bacillariophyceae, and Chlorophyceae, and the dominant species were Oscillatoria subtillissima, Dactylococcopsis irregularis, Euglena caudata, Melosira granulata, Cyclotella meneghiniana, Chlorella vulgaris, and Scenedesmus quadricauda. The main environmental factors affecting the distribution of phytoplankton species in July were ammonium-nitrogen, dissolved oxygen, water temperature, and total phosphorus, while those in September were pH, water temperature, dissolved oxygen, transparency, and total nitrogen. Water transparency and zooplankton were the main factors affecting the biomass of Cryptophyceae, Pyrrophyceae, and Bacillariophyceae; while nitrogen, phosphorous, and dissolved oxygen were the main factors affecting the biomass of Cyanophyceae, Euglenophyceae, and Chlorophyceae.

结果表明：调查期间共鉴定出浮游植物384种，隶属于8门，浮游植物密度范围为2.01×105～57.60×105 cells·L-1；群落组成以蓝藻、裸藻、硅藻和绿藻为主，主要优势种有细微颤藻、无常蓝纤维藻、尾裸藻、颗粒直链藻、梅尼小环藻、普通小球藻、四尾栅藻等；7月影响浮游植物分布的主要环境因子依次为铵态氮、溶解氧、水温和总磷，而9月的pH值、水温、溶解氧、透明度和总氮含量对浮游植物的分布产生影响较大；其中，透明度和浮游动物量是影响隐藻、甲藻和硅藻藻类生物量的主要环境因子，而蓝藻、裸藻、绿藻主要受水体氮磷营养盐浓度和溶解氧的影响。

Gracilis were applied to investigate the effect of proplastid on adaptability, in which such structure was found to be important to the competitiveness during heterotrophic growth in the dark; 2 a new procedure for differential display technology was developed and used to study the influence of plastid on nuclear gene expression, with which it was shown that the loss of plastid could cause remarkable changes in expression of certain nuclear genes.

本文主要有两点突出之处：1）应用裸藻褪色突变株与野生型的生长竞争实验探讨了原质体对于裸藻的适应意义，发现在黑暗环境和异养生长条件下原质体对于细胞的生存竞争有重要作用；2）改进了一种差异显示技术并利用该技术来研究质体的有无对基因表达的影响，证明质体丢失可导致某些核基因表达的显著变化。

Paramylum A starchlike polysaccharide composed of β(1,3)-linked units of glucose, which is the assimilation product of euglenas.

裸藻淀粉：一种淀粉状多聚糖，由β-1，3键连接的葡萄糖单位组成，是裸藻属的同化产物。

In most modern classifications, replacement for the Protista; includes: Protozoa; Euglenophyta; Chlorophyta; Cryptophyta; Heterokontophyta; Rhodophyta; unicellular protists and their descendant multicellular organisms: regarded as distinct from plants and animals.

在大部分分类中，取代protista；包含原生动物；裸藻门；绿藻门；隐藻门；红藻门；单细胞原生生物及它们的多细胞有机体后代；与动植物截然不同。

Results 18 microalgae species were detected from the 42 samples including 4 species in Cyanophyta, 9 in chlorophyta, 4 in bacillariophyta and 1 in Euglenophyta.

结果 共发现18种微藻，包括4种蓝藻、9种绿藻、4种硅藻、1种裸藻。

The dominant microalgae species in the early period of shrimp culture ponds were Bacillariophyta and Chlorophyta, which was up to 80%~90% of total microalgae abundance.

处于养殖后期的8口池塘，微型藻类种类数量相对较少，藻细胞密度相对较高，优势种类主要是颤藻和裸藻。

Euglenophyta Formerly, a phylum of aquatic single-celled protoctists that swim using one or more UNDULIPODIA, now classified as a class, the Euglenida, of the phylum Discomitochondria.

裸藻门：以前分为水生单细胞原生生物的一个门，用一条或多条波动足游动，现在作为一个分类等级，被分为 discomitochondria 门的裸藻类。

The experiments also showed that Eclean restrained the growth of some blue algae such as anabaena flos-aquae and Oscillatoria tennis and some green algae such as chlorella. vulgaris. This shows that the seaweed extract Eclean is very important and very useful in controlling the blue algae water bloom.

EClean对不同藻类的抑制性试验表明，EClean对蓝藻门的水华鱼腥藻(Anabaenaflos-aquae)、小颤藻和绿藻门的小球藻有明显的抑制作用，对绿藻门的斜生栅藻和裸藻门的血红裸藻的生长有一定的促进作用，显示出EClean对蓝藻性水华的治理具有重要意义。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
