南极

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。

An Australian Antarctic Division glaciologist said the ice chunks, spottedby satellite photography, had passed the Auckland Islands and were heading towards the main South Island, about 450 kilometres (280 miles) northeast.

一名澳大利亚南极署的冰河专家说，卫星图像显示，这些冰块已经通过了奥克兰群岛，正向着距东北部450公里外的新西兰主要的南岛飘去。

The map itself was finished in the middle of last year, but the previous Interior Department didn't want to release it and other Antarctic maps, said map co-author Richard Williams Jr., a glaciologist for the USGS.

地图合编者美国地质调查局的冰川学家Richard Williams Jr。说这张地图本身是于去年中旬绘制完成，可是前内政部并不想公布它和其它的南极地图。

During the 26th Antarctic expedition to study deep ice core drilling team will carry out the preparatory work, in the Kunlun station to build a deep ice core drilling site, while continuing to carry out the Zhongshan Station-Dome A cross-section of glaciology observations, Dome A site measurement of the Hong Kong Observatory and astronomical observations and mapping study visits, and will complete the second phase of the Kunlun station, including the installation and commissioning of sewage treatment and other equipment.

第26次南极考察期间，考察队员将进行深冰芯钻探的前期准备工作，在昆仑站构筑深冰芯钻探的场地，同时继续开展中山站-Dome A断面的冰川学观测、Dome A天文台址测量和天文观测以及测绘学考察，并将完成昆仑站的二期工程，包括安装调试污水处理等设备。

The team members were expected to continue their journey to Kunlun Station, some 7000m southeast of Dome A. They will conduct research in multiple scientific fields, including glaciology, astronomy, mapology and geophysics.

按计划，考察队将继续向位于冰穹A西南方向约7公里的中国南极昆仑站挺进，进行冰川、天文、测绘、地球物理等多学科综合考察。

Glaciology|Glaciologically,''ice age'' is often used to mean a period of ice sheets in the northern and southern hemispheres; by this definition we are still in an ice age ( because the

冰河通常用来指一段冰盖在南北半球；由这个定义，我们还处在一个冰期(因为南极和格陵兰冰盖存在)。

Australian Antarctic Division glaciology program head Ian Allison said sea ice losses in west Antarctica over the past 30 years had been more than offset by increases in the Ross Sea region, just one sector of east Antarctica.

澳大利亚南极冰川项目负责人伊恩·艾利森表示，近30年来，南极洲西部地区海冰消失已被东部罗斯海这一个地区海冰增加所抵消。

The Grove Mountains expedition is one of the highlights of this expedition, after surveying and mapping personnel have conducted four times the Grove Mountains mapping, geology and glaciology comprehensive survey, field mapping of the Grove Mountains, the surface of the core area of 110 square kilometers topographic maps and maps of protected areas; emplaced 10 geodetic control points, seven ice-flow monitoring stations; the use of different resolution optical images, SAR images, carried out the distribution of the ice fissure information extraction research, production of the Grove Mountains region Flat satellite image maps, digital elevation models and a wide range of blue ice distribution maps, for my recovery to the 9834 Antarctic meteorites have made contributions.

格罗夫山考察是本次考察的亮点之一，此前，测绘人员已进行过4次格罗夫山测绘、地质与冰川学综合考察，实地测绘了格罗夫山核心区110平方千米表面地形图和保护区地图；布设了10个大地测量控制点、7个冰流速监测站；利用不同分辨率光学影像、SAR影像等，进行了冰裂隙分布信息提取研究，制作了格罗夫山地区平面卫星影像图、大范围数字高程模型及蓝冰分布图，为我国回收到9834块南极陨石作出了贡献。

Various people including Charles Hapgood and Erich von Daniken considered this as a sign of the discovery of the continent of Antarctica many centuries before the traditionally accepted date, and even as a proof for the presence of extraterrestrial civilizations, which were supposed to have drawn the original map.

不同的人，包括查理斯和冯丹尼肯认为这是比传统上承认的日子早许多世纪就发现南极大陆的标志，正巧是证明存在着地外文明，是他们绘制了最初的地图。

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。
