It is two-toned - one half is black, the other shining white - and strangely shaped, flattened at the poles and squashed at the sides as well.

它有一个较亮的半球面和一个较暗的半球面，并且有着古怪的外形，两极平坦凹陷，并且有着环绕球体半圈的赤道脊，使它看上去像一个核桃的外形。

Between the poles of amoral cynicism and rank religious hypocrisy was a messy space in which people tried to find ways of dealing with their insecurity and self-doubt.

在非道德的犬儒主义与恶心的宗教伪善这两极之间，是一片混乱地带，人们为缺乏安全感及自我怀疑所困扰着。

This time, however, the rush to the poles is more of acrawl, which means we could be headed toward a very weak solar maximum in2013—and it may delay or even prevent the start of the next solar cycle.

然而，这一次，向两极移动的冕流却慢腾腾的，它意味着我们可能将在2013年经历一个非常弱的太阳活动峰值——这也许会延迟甚至阻止下个太阳活动周期的开始。

The ice sheets at the poles can disintegrate rapidly once they start melting, and sea-level rises of a few meters per century are not unheard of.

地球两极的大冰原一旦开始融化就会快速地分解，而海平面每世纪升高几米也不是危言耸听。

「These buried ice sheets that extend from the poles all the way down to 45 degrees or so (north and south latitude) don「t quite cover half of the planet, but (they) come close,」 he said.

「这些埋藏着的冰原从两极一直延伸到(北纬和南纬)45度左右，没能完全覆盖半个火星，但(覆盖面)接近这一水平。」Shane Byrne表示。

Ozone recovery at the poles will be minimally affected by climate change.

两极地区的臭氧恢复将受气候变化的影响最小。

THERE is a lot of water on Earth, but more than 97% of it is salty and over half of the remainder is frozen at the poles or in glaciers.

尽管地球上水资源丰富，但是超过97%的水为咸水，而在剩下的不到3%的水又有一半以上要么是冻结在两极，要么是构成了冰川。

The history and romanticism of 「formidable and difficult to reach」 places drew Seaman to the poles as a photographic subject.

「可怕而难以触及的」两极的历史和浪漫主义吸引了希曼将其作为摄影主题。

Aurorae are caused by the interaction of the solar wind with Earth」s magnetic field and so are particularly prevalent at the poles where the magnetic forces are strongest.

极光是太阳风与地球磁场相互作用产生的，在两极磁场最强烈的地方，极光很常见。

The researchers found the most notable phytoplankton declines in waters near the poles and in the tropics, as well as the open ocean.

研究人员发现，在两极附近的水域和热带地区浮游植物的跌幅最为显着，在开阔的海洋也是如此。

The Earth is an ellipsoid, slightly flattened at the poles and bulging at the equator.

地球是椭圆体，在两极稍扁，在赤道凸起。

As on Earth, the particles are channelled to the poles by the planet's magnetic field.

在地球，原子内粒子在地球磁场的作用下呈流状分布在两极。
