The Antarctic species have few special adaptations for polar life.

南物种对地生活几乎没有什么特别适应性改变。

Polar surface waters most likely will become undersaturated for aragonite before the end of this century.

在本世纪结，地海水表层有可能变得对霰石不饱和。

In this area the climate changes from cool, humid, and subpolar to the frozen conditions of Antarctica.

这个地气候变化大，副地气候凉爽湿润，到南洲冰天雪地。

The relationship between arctic tropopause height and surface air temperature is discussed by using the aerological sounding and surface data during 1977-1990 in Beijing area.

利用北京地1977—1990高空、地面资料，讨论了地对流层顶与地面温度关系。
