The extinction or appearance of these Ostracoda always occurred in a short time interval, and can be correlated locally and globally, so they are of importance in bioeventstratigraphy. This article listed six such biological events in Qaidam Basin and discussed their causes. The extinction of Cetacella reflected temperature decrease at global scale and changes of palaeoclimate zones during the latest Jurassic and the earliest Cretaceous; The rapid decline of Cypridea in the earliest Cretaceous may be a result of the strikes of small planets; at the latest middle-Eocene Austrocypris became extinct, and at Oligocene Hemicyprinotus disappeared. These events related to the changes of the geological conditions at that time. The explosion of Cyprideis at the middle-Miocene was because the rise of Qinghai-Xizang Plateau which resulted in the dry climate and development of salt lakes.

这些水生生物的绝灭或发生均很迅速，在区域或全球范围内均可对比，具有生物事件地层学意义：Cetacella属的绝灭可能是侏罗、白垩纪之交全球性的古气候降温和气候带变化在柴达木盆地的反映；早白垩世之后Cypridea的迅速衰退是地外因素灾变的结果；中始新世晚期的Austrocypris的绝灭、渐新世Hemicyprinotus的绝灭都与当时地质条件的改变存在著内在的联系；中中新世Cyprideis的爆发推断是青藏高原隆升，导致气候乾燥、湖水咸化的结果；而晚更新世晚期1。

Three main methods with lacustrine carbonates have been used to reconstruct the lake water palaeo-temperature at present. First, the technique of isotopic geological thermometer, since being put forward to reconstruct sea-water paleo-temperature, was subsequently introduced into lacustrine carbonate sediments for constructing lake-water based upon the function relationship between lake-water temperature and the oxygen isotopic compositions of lacustrine carbonate and lake-water. Second, paleo-temperature of the lake-water can be reconstructed by determining Mg/Ca values of the lacustrine ostracode shells. And third, paleo-temperature of the lake-water can be reconstructed based upon the statistic model between the oxygen isotopic composition of lacustrine carbonate and the Lake-water temperature by testing the modem hydrogeological parameters and some relevant isotopic data of the lake basin.

目前利用湖泊碳酸盐对湖泊古水温进行重建主要有三种方式，一是运用同位素地质温度计原理，利用水温与湖泊碳酸盐氧同位素值和湖水氧同位素值三者之间的函数关系，对湖泊古水温做定量研究；二是通过测定介壳[Mg(上标 2+)]/[Ca(上标 2+)]进而重建古水温；三是通过测定湖泊流域范围内现代水文气象参数及一些相关的同位素资料直接建立起湖泊自生碳酸盐氧同位素值与温度间的统计模型。

露珠对湖水说道；你是在荷叶下面的大露珠，我是在荷叶上面的较小的露珠。

You have destroyed your vow to Eul when you met on that fateful summers noon as a young and lost map developer who didn't have a true purpose in the world and decided to ask those with more wisdom because you were afraid of being unable to live up to the great expectations bestowed upon you, down at the serene windy lake with it's glassy surface and lone fisherman in a small and easily overturnable boat hovering quite near the center worrying about feeding his family and the deers trotting off in the distance being jealously eyed by small rabbits who envied their youthfulness but at the same time were glad they were such innocent symbols of cuteness that were sometimes ignored by the American MEDIA, you have destroyed the oath you took with him as he decided to leave the glowing jeweled crown with the more exuberant youth of his dying generation.

在那个命运中的夏午，当时还是一个年轻且彷徨的地图开发员的你破坏了你和Eul的约定。因为你在世上没有一个确定的目标。所以你决定去请教那些更有智慧的家伙们，因为你无法承受如此大的期待而你为此感到恐惧，低着头看着碧波荡漾的湖水、那玻璃一样的湖面的非常靠近中心的位置有一个乘着简陋的随时都有沉船危险的轻舟的孤独的渔夫正在为养活他的家庭而感到担心。林中的小鹿们踏着碎步而在另一边小兔子们则充满嫉妒地注视着它们。兔子们羡慕它们的活力同时又为自己的可爱能作为纯真的象征而感到高兴。因为有时这一点能够迷惑美国媒体，你已经破坏了你和他在他决定把镶嵌着炽热宝石的皇冠留给更有朝气的年轻人作为他的继承人时的誓约。

Example: natural lake in the middle of remote forest, BOD10, COD15, iron 3.6, no other oxidable material.

偏远森林中部的天然湖水，BOD10， COD15，铁3.6，无其他氧化物。

As we paddled on the still water, we felt like we were the only two people on Earth.

我们在静止的湖水上划桨前进时，觉得自己像是地表上唯一的两个人。

An abrupt increase of seasonal inflow occurred at about 10.2 ka BP, as suggested by a layer rich in Ruppia L.

正是由于湖区夏季风降雨增大，湖水位迅速升高到4米以上，沉水植物川蔓藻从此未能在湖中央生长。

Scarily, it did not take much estrogen to affect the fish — just 5 or 6 nanograms, or billionths of a gram, per liter of lake water.

令人吃惊的是，每升湖水中仅仅5'6纳克或者十亿分之一克的雌激素就能对鱼类产生如此影响。

Addition of wastewater or nutrientsto lake water in various doses had stimulated the growth of alga Scenedesmus obliguus.

在东湖湖水样品中添加排入东湖的主要污水或营养物进行藻类测试，观察它们对斜生橱藻的生长促进作用。

When the culture medium was the mixture of lake water and sediments, the average absorption velocity of DP was 2 ng for per 10000 Microcystis aerugilnosa and 7.6 ng for per 10000 Scenedesmus obiquus respectively everyday. And the average increasing velocity was 1.19×10~5 per mL and 3.7×10~4 per mL respectively everyday.

在沉积物和湖水作培养基的情况下，每1万个微囊藻吸收水中的溶解性磷的平均速率约为2ng／天，斜生栅藻约为7.6ng／天，微囊藻和栅藻的平均增长速率为1.19×10~5个／mL·d和3.7×10~4个／mL·d。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
