The paleochemical characteristics of paleoseawater from the Permian conodont were reconstructed through contrastive researches of REE and Ce anomalies. The resuts show that geochemical characteristics of the conodont may be regarded as a useful proxy to reconstruct the paleoenvironment.

此外，作者对牙形石的稀土元素组成进行了分析，并且发现牙形石的REE组成和Ce异常与古海水氧化还原条件有一定的相关性，可以指示古海水的信息。

Shining light selectively on one eyespot changes the beating of the adjacent cilia. The resulting local changes in water flow are sufficient to alter the direction of swimming, computer simulations of larval swimming show.

计算机模拟幼虫游动图像显示：闪烁的光线在眼点上分布不均，这样就改变了临近纤毛拍打海水的幅度，由此引起的海水浮动足以改变生物游动的方向。

5The distribution patterns of rare earth element compositions in the hydrothermal components are similar to that of pacific seawater. This infers the complex and significant interactions of hydrothermal fluid with surrounding seawater during its diffusing process. Dissolved trace metals in the hydrothermal fluid can be removed by settling terrigenous or biogenic particulates and precipitated quickly from the hydrothermal plume round the vent. On the other hand, hydrothermal particulates would also scavenge some elements from the seawater to coprecipitate into the sediments.

5岩芯沉积物中热液源组分携带的稀土元素组成具有类似海水的分布模式，反映了热液流体喷出海底后与其它物源物质之间的复杂的相互作用：一方面大量生物和陆源碎屑物质的快速沉积导致溶解态的热液源物质被快速清扫，无法向外扩散，快速堆积在热液喷口附近；另一方面，随热液羽状体向外扩散的颗粒态热液源物质也清扫海水中的元素共同进入沉积物。

There are three basic processes that cause a c hange in oceanic salinity.

海水盐度如果我们分析海水的盐度，会发现地区间只有轻微的变化，然而有些小的变化是重要的。

The paleochemical characteristics of paleoseawater from the Early Ordovician of Yangtze Craton are reconstructed through contrastive research of REE and trace element composition, Ce anomalies and Sm/Nd ratio of conodonts.

利用激光剥蚀电感耦合等离子质谱对扬子克拉通宜昌三峡地区早奥陶世不同时期海相碳酸盐岩地层中的牙形石个体进行了原位分析，并与已发表的世界其他地区古海水的稀土元素组成进行了比较，利用REE和微量元素组成、δCe和Sm/Nd比值等地球化学指标恢复了该时期古海水的地球化学性质。

When it's time to lay eggs, the eels and their kidneys will return to their beginnings.

而当它们要产卵的时候，它们又会回到海水当中，而它们的肾脏又会发生变化来适应海水的高盐度。

When it's time to lay eggs the eels and their kidneys will return to their beginnings.

而当它们要产卵的时候，它们又会回到海水当中，而它们的肾脏又会发生变化来顺应海水的高盐度。

When its time to lay eggs, the eels and their kidneys will return to their beginnings.

而当它们要产卵的时候，它们又会回到海水当中，而它们的肾脏又会发生变化来适应海水的高盐度。

The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean.

海水盐度如果我们分析海水的盐度，会发现地区间只有轻微的变化，然而有些小的变化是重要的。

In the Weddell Sea Antarctica, the densest waterin theoceans is formed as a result of this freezing process,whichincreases the salinity of cold water.

在南极洲边缘的威德尔海中，结冰过程增加低温海水的盐度，从而形成了浓度最大的海水。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
