北极的

The model of three-dimensional temperature field of Arctic sea ice is established, andthe two-dimensional velocity of tidal motion in the horizontal direction is considered,meanwhile a way to determine the boundary is found.

2建立了关于北极海冰温度场的三维模型，考虑了水平方向的二维流速问题，给出了确定开边界条件的方法。

Don Gautier, who works for that agency, retorts that it has never done a systematic study of the Arctic, or put a figure on its energy riches.

在该机构工作的唐·戈蒂埃反驳说，该机构从来没有做过对北极地区的系统调查，或公布其能源财富的数字。

The T-Touch Multi-function will indicate the degree of magnetic deviation between the geographic and magnetic North Pole on the digital display.

在T -触摸多功能将表明之间的地理和磁北极磁场偏差的数字显示的程度。

Compass needles point to the earth's north geographic pole because the dipole's south magnetic pole lies near it.

（北针的磁针之所以会指向地球的地理北极，就是因为上述偶极的磁南极正好在那附近。

In this study, they constructed a ground squirrel protein database using computational methods. They further analyzed the protein expression in hibernating ground squirrels using high-throughput label-free LC-MS/MS.

在这项研究中，该研究组通过计算手段构建了全新的地鼠蛋白库，并首次使用无标记的高通量蛋白质谱技术系统分析了北极地鼠在冬眠各个过程中蛋白质水平的变化。

We constructed a ground squirrel protein database for protein identification and used a label-free shotgun proteomic approach to analyze protein expression throughout the torpor-arousal cycle during hibernation in arctic ground squirrels.

在这项研究中，该研究组通过计算手段构建了全新的地鼠蛋白库，并首次使用无标记的高通量蛋白质谱技术系统分析了北极地鼠在冬眠各个过程中蛋白质水平的变化。

The loss of pack ice also makes sea-transport in the Arctic easier for longer periods each year.

浮冰块的减少也使得北极区的更长时期的海运变得更容易。

In the 4.6 billion year history of our planet, the present arrangement of cold ice-covered regions at the northern and southern poles represents a recent development.

在地球46亿年的历史中，现有南北极寒冷的覆冰区域分布代表了地球最近的发展。

这些图像是在2008.11.17得到的，覆盖了月球南极的霍沃斯火山口和西部的Seares火山，接近北极。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
