北冰洋

The arctic tundra forms a circumpolar band between the Arctic Ocean and the polar ice caps to the north and the coniferous forests to the south.

北极冻原在北部的北冰洋和极地冰盖与南部的针叶树森林之间，形成了一个环绕极地的带。

"The thing is, the Canadian Arctic has a totally different ice regime than the Arctic Ocean," says Stephen Howell, a climatologist at the Interdisciplinary Center on Climate Change at the University of Waterloo in Ontario.

"问题是加拿大北极区域的冰层情况与北冰洋的完全不同。"斯蒂芬。豪威尔说。他是安大略省滑铁卢大学气候变化跨学科研究中心的气候学家。

Eric DeWeaver, the physical climatologist on the International Polar Bear Science Team and a professor of atmospheric and oceanic sciences in the University of Wisconsin-Madison, evaluated existing climate models to identify those that best represent observed changes in sea ice - a crucial component of polar bear habitat - and which are expected to best predict future conditions in the Arctic.

Eric DeWeaver 是国际北极熊科考队的一名物理气候学家，也是威斯康星大学麦迪逊分校研究大气及海洋科学的教授，他对现存的气候模型作了评测以确定哪些模型最能显示：在北极熊栖息地的重要组成部分——海冰中观测到的变化以及哪些是人们所希望的最能预测北冰洋未来情况的模型。

Remember as a child in the yard of the large shade trees, the Arctic Ocean to the soft drink bottle, the players eating noodles, cucumber root again, more than indescribably happy.

记得小时候在院子里的大树下乘凉，来瓶北冰洋的汽水，吃着大腕的炸酱面、再来根黄瓜，别提多开心了。

Our data will help scientists better understand how fast the volume of Arctic ice is decreasing and how soon we might see a nearly ice-free Arctic in the summer.

我们的数据能够帮助科学家们更好的了解北极冰层的体积减少的如何快和或许我们多快在夏季就能看到一个几乎无冰的北冰洋。

The crystal profile of the ice core (its length is 4.86 m) located at 74°58.614′N, 160°31.830′W shows the evidence of an ice ridge changed into hummock.

由位于北冰洋74°58.614′N，160°31.830′W，长4.86 m的冰心样的晶体结构分析发现它过去为冰脊，后经融化-冻结改造形成冰丘的证据。

金色和紫色的夕阳把冰点以下的北冰洋水染成了五颜六色。

In Turkey and China and among the Inuit, both men and women wore trousers.

在土耳其和中国以及因纽特人（北美特别是加拿大北冰洋地区和格陵兰岛的爱斯基摩人），男子和妇女都穿裤子。

However, the Finnish troops in the balance of forces is very adverse circumstances, by virtue of 1927-1939 in the Karelian Isthmus built "Mannerheim line" of the strong fortifications, the use of cold and swamp forests, a favorable position to fight back war , positional warfare, and expendable to surround and annihilate war, except in the Arctic Ocean so Soviet Moldova and Sara Bei Cai rapid progress in the region outside, in the Karelian Isthmus and Ladoga Lake area suffered heavy casualties, the main positions of the Finnish Army did not Jiugong grams.

然而，芬军在力量对比非常不利的情况下，凭藉1927—1939年在卡累利阿地峡修建的"曼纳海姆防线"的坚固工事，利用严寒和沼泽森林的有利地形，展开反击战、阵地战和消耗性围歼战，因此苏军除在北冰洋的贝柴摩和萨拉地区进展较快外，在卡累利阿地峡和拉多加湖一带伤亡惨重，对芬军主阵地久攻不克。

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。
