Temporal changes in zooplankton composition occurred in both ponds with Cladocera appearing in abundance later, in the fourth week, whereas copepods and rotifers were well represented since the beginning.

浮游动物组成短暂的变化在两个塘同时出现随着枝角类较晚出现一定丰度，在第四周左右，然而桡足类和轮虫自开始就出现。

Five water sampling collected from Miyun Reservoir were observed quantitatively. Thirty-six species of zooplankton including 11 protozoan, 15 rotifers,6 cladocero and 4 copepoda were found. The results showed the eutrophicational feature, such as lower biodiversity ,miniaturization and more amount.

浮游动物共检出4门，30属，36种；浮游动物群落具有原生动物数量多，轮虫次之，枝角类与桡足类量少的特点，呈现出浮游动物数量大、小型化、多样性低等伴随水体富营养化出现的特征。

Cage culture of the mandarin fish also decreased the dissolved oxygen concentrations, the species number and biomass of the zoobenthos around the cage area, but had no significant effects on the water temperature, pH, transparency, species composition of phytoplankton and zoobenthos, and the species composition and biomass of rotifers, cladecerans and copepods.

网箱养鳜同时减少了网箱周围的溶氧、底栖动物的种类数和生物量，但对水温、pH值、透明度、浮游植物种类、原生动物种类以及轮虫、枝角类和桡足类的种类和生物量影响较小。

Marine copepods are kinds of small crustacean zooplankton,and are high quality food for larviculture of marine fishes.

摘 要：海洋桡足类作为小型甲壳动物，是鱼虾类良好的天然饵料，其繁殖和培养将在现代海水养殖业中发挥重要的作用。

Pearson＇s Correlation Analysis showed negative correlation between meiofauna abundance and phytoplankton biomass in term of carbon and nitrogen (-0.969 and -0.947, P.05). The total of 14 meiofauna groups were identified.

按生物量，海洋线虫(35.9％)、介形类(32.6％)、多毛类(13.7％)和桡足类(8.3％)共同构成小型动物的优势类群，80％以上的小型生物分布在0—2cn以浅表层内。

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。
