藻类的

Many phytoplankton and autotroph absorb the DIN of the bottom water that decrease content of DIN in bottom water and change the fluxes of the DIN. And the activity of those phytoplankton and autotroph can even change the direction of DINS fluxes.

在有光的条件下，浮游藻类和一些光自养生物对沉积物水界面溶解态的营养盐的直接吸收，从而减少了上覆水中可与沉积物可交换的营养盐的含量；浮游植物的活动甚至有可能改变无机氮在沉积物水界面的扩散方向。

The comparison between the obtained EC50 values and toxicity data from the literature points out the good agreement between the BOD bottle test (Raphidocelis su.) and those of nine widely used test methods, i.e., Fathead minnow, Vibrio fi., Microtox, Polytox, Spriotox, Shk1, Activated sludge, Daphina ma. and Tetrahymena. In this study, log Kow values of narcosis Ι compounds (using the BOD bottle test and nine bioassays) were reported.

实验中选定DO观测终点所求得的毒性数据与其他物种进行回归分析，回归结果则皆呈现高度相关（R2值≧0.84），这可推论出藻类与其他物种的分析方法（不含Nitrosomonas）的致毒机制有很高的相关性，且可知本试验方法不仅敏感性高且与其他的物种且有良好的相关性可做为替代性试验。

The high pressure, shock wave, acoustic streaming andshear force caused by ultrasonic cavitation damaged the cyanobacterial cells,produced pits and holes on the surface, fractured the trichomes, and disrupted the gasvacuole of algae.

超声空化导致的高压、冲击波、声流和剪切力，在藻类细胞表面产生坑穴状的损伤，折断藻体的藻丝，破碎藻细胞的气囊结构。

The abundance of epiphytic algae on seagrasses, the result of interactions among many biotic and/or abiotic factors, can largely determine the impact intensity and the direction of the pros and cons.

海草叶片上的附生藻类负荷量很大程度上决定了其对海草影响的强度及利弊的方向，它是各种非生物因子及生物因子相互作用的结果。

Both three systems showed low abundance of herbivorous fishes. Relative abundance of fishes and coral reefs was least in the anthropogenically impacted systems. However, relative abundance of fishes did not differ in the protected and non-protected systems, suggesting the little effect of marine protection area.

而受人为活动影响的珊瑚礁生态系则显示，破坏的保护区之鱼类和珊瑚比例最少，但藻类最多；然而鱼类比例在保护区和非保护区间，除非是受到高度管制的保护区，鱼类比例会较高外，二区间的鱼类比例差异并不大，显示保护区可能未受到较妥当的保护，无法发挥其效能。

Clearly, Volvox evolved from similar algae that exist only as single cells, but until now the genetics of the process have been obscure.

显然团藻是从类似的只有单个细胞的藻类进化来的，但这个进化过程的遗传学机理迄今为止还不清楚。

Approximately 30 mg of fresh algal material was extracted by homogenising it in ice-cold 5% 5-sulfosalicylic acid solution containing 6.3 mM diethylentriaminepentaacetic acid, according to De Knecht et al.

大约30毫克的淡水藻类物质提取homogenising在冰冷的5％的5-磺基水杨酸溶液的载有6.3毫米三乙四胺五乙酸，根据De Knecht等人（1994年）。

Cloudy water in the aquarium is caused by a bacteria bloom, while green water is an algae bloom.

水族馆里的混浊水质是由细菌繁殖引起的，而绿色的水是由藻类繁殖引起的。

Antarctic krill, such as this specimen in the Weddell Sea with a stomach full of yellow algae, are a critical link in the ocean food web.

南极的磷虾，这样的标本在Weddell海有一个饱满的胃部充满黄色的藻类，是一种供不应求的海洋食物链网。

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

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
