In the Antarctic, the temperature rarely rises above freezing point.

南极，很少升到零上。

The temperature is below zero.

零。

Ice forms at 0'c.

摄氏零时结冰。

There is no heat for the subfreezing temperatures, and the bunks are planks of plywood attached to metal scaffolding.

他们睡木板搭成的高低铺上，虽然北京的冬夜经零，但他们的工棚当然不会有暖。

Some controversal points, like the absolute value of entropy and the proof of the unattainability of absolute zero by means of Carnot cycle, are discussed.

本文还讨论了一般所争论的问题,如熵的绝对值问题,利用卡诺循环证明绝对零不能达到问题。
