浮游

The terrestrialand aquatic environmental impacts of veterinary drugs was expounded both on terrestrial environmental impacts of veterinary drugs upon plants, soil animals, soil microorganism and protozoa, and ecotoxicity of veterinary drugs to plankton, microorganism, fish and Crustacea.

综述了兽药对陆生和水生生态环境影响方面的研究进展，探讨了兽药对陆生植物、土壤动物、土壤微生物与原生生物等陆生生态环境的影响及对浮游类生物与微生物、鱼虾与水体甲壳动物等水生生态环境的影响及其生态毒理效应。

Significant differences in the structure of crustacean community were found among Stations Ⅰ,Ⅱ,Ⅲ and Ⅳ.

浮游甲壳动物群落结构在东湖Ⅰ、Ⅱ、Ⅲ、Ⅳ站间具有显著差异。

Other forms of food are planktonic crustaceans and algae that may develope on coral or nearby rocks.

其他形式的食物是浮游甲壳类动物和藻类，可能制定关於珊瑚或附近的岩石。

More experiences approved that the content of the cupper in African atmospheric particles is fatal to the phytoplankton.

更多的试验证实，对于两类浮游植物而言，非洲大气粒子中的铜含量是致命的。

More experiences approved that thecontent of the cupper in African atmospheric particles is fatal tothe phytoplankton.

更多的试验证实，对于两类浮游植物而言，非洲大气粒子中的铜含量是致命的。

Most research so far focused on the decline in calcification of corals, other reef organisms and some major planktonic groups of the open ocean due to this acidification. But less is known about the long-term effect of decalcification on the ecosystem.

目前大部分研究已注意到海洋酸化造成珊瑚钙化作用的减缓，以及礁石有机物、某些主要浮游生物群所受到的影响；但对生态系统「脱钙作用」的发生会造成什么长远的效果，则所知甚少。

The planktonic larvae of echinoderms and decapod crustaceans have increased in abundance from 1958 to 2005, and especially since the mid-1980s, as North Sea SST has increased.

棘皮类和甲壳纲的十足类浮游动物的幼体从1958年到2005年一直处于增长状态，尤其是在80年代中期，这是由于北海海水的表面温度增长的缘故。

This study shows that the bottom-water ventilation was relatively stronger during the postglacial period than during the glacial and deglaciation periods, which is indicated by the oxygen concentration of bottom-water and the changes of microfossil assemblages.

首次在冲绳海槽识别出了末次冰消期浮游有孔虫δ13C的宽幅低值事件，并发现该事件与热带太平洋及其边缘海表层水的δ13C低值事件具有非常好的可比性，说明末次冰消期冲绳海槽表层水体的δ13C值低值事件可能是直接受热带太平洋表层水的影响所致。

The grazing of micrzooplankton,especially heterotrophic dinoflagellate was one of the important factors of diatom bloom decline.

微型浮游动物的摄食，尤其是异养的螺旋环沟藻的摄食，是水华消亡的主要原因之一。

Preliminary analysis has shown that the diversity of Jiaozhou Bay dinoflagellate is rich.

研究表明胶州湾表层海水浮游甲藻具有丰富的遗传多样性。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
