As shown by the results of the qualitative and quantitative micropaleontological analyses, the basic factor controlling the distribution of the foraminiferal and ostracod assemblages is water depth and offshore distance, although water temperature, currents and salinity have strong influence on their distribution.

东海沉积中有孔虫、介形虫定量研究的结果表明：河口、陆架内部、中部、外部、陆坡与海槽，分別具有不同的有孔虫、介形虫组合，它们受水深，水温与盐度等因素控制。

The benthic meiofauna was quantitatively investigated from 19 stations in the sea areas of the First-phase Project of Yangshan Deepwater Port in November, 2005 and ten meiofauna groups, including nematodan, copepodan, polychaetan, bivalvian, ostracodan, amphipodan, tanaidacean,cumacean, gastropodan and foraminiferan, were recorded.

2005年11月对洋山深水港一期工程海域19个站位的小型底栖动物进行了调查，共获得10个主要类群，包括线虫、桡足类、多毛类、双壳类、介形类、端足类、异足类、涟虫、腹足类和有孔虫。

Different plant expression vectors had been respectively transferred into upland cotton cultivars Jinman12, Jinmian7, Xinluzao1 and Jihe321 via Agrobacterium tumfaciens transformation. These vectors carried cryIAc3 gene, which encodes Bacillus thuringiensis δ-endotoxin, under the control of chimeric OM promoter, CaMV 35S promoter, and cotton leaf curl virus RP promoter respectively; snowdrop lectin gene (Galanthus nivals agglutinin, gna) trans-regulated by rolC promoter controlled TGAla factor; and multivalent expression construct of both cryIAc3-cpti fusion gene and gna gene. A large number of transgenic plants and their progenies had been obtained.

为了提高外源基因的表达量，延缓害虫产生耐受性，本文通过将携带有分别在高效复合OM启动子，CaMV35S启动子及棉花曲叶病毒RP启动子控制下的苏云金杆菌杀虫毒蛋白基因cryIAc3；反式调节因子增强韧皮部表达的雪花莲外源凝集素(Galanthus nivals agglutinin，GNA)基因；以及同时含有cryIAc3、豇豆胰蛋白酶抑制剂基因和gna三价抗虫基因的植物表达载体，以根农杆菌介导法分别将这些表达载体导入了陆地棉新陆早1号、晋棉7号、晋棉12号和冀合321等我国西北棉花主要栽培品种，经体细胞胚再生获得了大批转基因再生植株。

Results The morphology and asexual reproduction of Cloudina are broadly similar to modern serpulid annelids and its flourishing is somewhat coeval and corresponding to a positive excursion of δ13C.

结果 Cloudina可能是多毛类龙介虫，二者在管体形态特征、无性繁殖方式等方面存在可比性；Cloudina的出现都对应着碳同位素的明显正漂移，具有基本等时的特点。

Liew thought they were likely to be tiny crustaceans called ostracods (also known as 'sea fireflies').

他认为它们大概是一种称作种虾的细小介虫。

Also it influenced the growth of algae and the living of shrimps at level of 0.033 mg/L, but no significant toxic effects on other zooplankton such as Daphnia magma, ostracods, rotifers and so on was detected.

结果表明，莠去津浓度为0.023 mg/L时对藻类生长会产生影响；浓度为0.033 mg/L时对藻类生长和河虾生存均会产生影响，但对其他浮游动物，如大型溞、介虫、轮虫等未产生显著的毒性效应。

The greyish-green mudstone in the Member 4 of Quantou Formation richs in pyrite. The grey and grayish-black mudstone in the Member 1 of Qingshankou Formation is of Ostracods、Esthenaus fossils and grainy pyrite .

泉四段上部为灰绿色的泥岩，青一段下部为深灰色、灰黑色的泥岩，可见介形虫、叶肢介，部分层位见粒状黄铁矿分布。

Cloning of insecticidal crystal protein gene and its expressing in E.

本研究从苏云金芽孢杆菌克隆得到野生型杀虫晶体蛋白基因，构建了用于细胞核或叶绿体转化的植物表达载体，并用激光微束穿刺法、土壤农杆菌介导法和基因枪法将杀虫蛋白基因导入油菜，获得了具有抗虫性的转基因植株。

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。
