藻类

Alkylbenzene, normal alkanes and alkylcyclohexane on the pyrolysates of P. Boryanum at 300℃ had uniform distribution and the relative content of them was similar, indicating that they originated from same precursors. Fatty acids, alcohol and ketone in algal cell are the possible precursors. For example, the precursor of relatively abundant C〓 alkylbenzene and alkylbenzene with C〓 side chain perhaps related with palmitic acid. N-alkylnaphthalene in pyrolysates at 300℃ probably derived from alkylation of cleavage products of aromatic steranes and terpanes.

在盘星藻300℃热解产物中，烷基苯、正烷烃和烷基环己烷碳数分布一致、各化合物的相对含量接近，表明它们有相同的来源，藻类体内的脂肪酸、醇和酮及细胞壁等物质可能是其母质，相对含量较高的碳数为16及侧链碳数为16的烷基苯类化合物，其前身物可能与软脂酸有关。300℃热解产物中的正烷基萘类化合物，可能由芳香甾、萜类的降解产物与直链烃类加成烷基化而形成。

In the absence of planktivorous fish, large-bodied cladocerans effectively control the abundance of algae of a broad size spectrum.

当缺乏食浮游生物性鱼类时，大型枝角类有效地控制了较大范围的藻类丰度。

The results pointed out that the environmental factors, such as nutrient enrichment, littoral zone sunlight and substrate types were very important in controlling community distribution.

结果表明沿岸带的光照、营养水平和基质类型可能是影响底栖藻类群落分布的扛要环境因子。

In temperate regions vascular epiphytes are rare: here most epiphytes are lichens, mosses, liverworts, and algae.

温带几乎没有附生的维管植物，附生植物大多为地衣、藓类、苔类和藻类。

Non-flowering plants include coniferous trees, mosses, liverworts, algae and fungi. You cannot see many non-flowering plants around you.

不开花植物包括针叶树，苔藓，欧龙牙草，藻类和真菌类，但是在我们周围见不到多少不开花植物。

The results indicated that the toxicity of malachite green to Isochrysis zhanjiangensiswas higher than Chlorella pyrenoidosa, and the 96 h EC50 of malachite green to the two algae were 0.133 mgl^(-1) and 0.017 mgl^(-1), respectively.

结果表明，孔雀石绿对两种藻类的生长具有较强的抑制效应，96 h的半抑制效应浓度(EC50)分别为0.133 mgl^(-1)和0.017 mgl^(-1)时属于高毒，而且对金藻的毒性大于小球藻。

The numerous macro-plants during the Doushantuoian were branching and semi-floated and erected on seafloor. They advanced the photosynthetic efficiency and increase oxygen in water to improve in environment for metazoans; and they served as a primary producer in the paleoecosystem to provide an alternative and new food of metazoan.

陡山沱期的宏体藻类多分枝并直立固着于海底，提高了光合作用的效率，增加了海中水体中的含氧量，不仅改善了环境，为依赖一定氧而生活、生长和繁殖的后生动物给予了必要的支持，而且作为生态系统中的必要基础，为宏体后生动物的快速发展和演化提供了一个新的食物源。

Algae and lichens may directly colonize and live on the surface of carbonate rocks. Through biochemical and physical processes, they bore and corrode the substrate, thus producing distinct biokarst microforms.

藻类、地衣可以直接殖居在碳酸盐岩表面，通过生物化学、生物物理过程对其基质产生钻孔溶蚀作用，并产生相应特征性的微形态。

Livebearing toothcarps, such as guppies, platies, black mollies and swordtails also eat algae.

卵胎生鳉科鱼类，例如孔雀鱼、月光鱼、黑摩丽和剑尾鱼也吃食藻类。

The algae are grown in narrow-necked glass bottles to produce hydrogen in the lab.

在实验室里，藻类生长通过狭窄的颈玻璃瓶生产氨气的环境下。
