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，虽然北京的冬夜气温已经零度以，但他们的工棚当然不会有暖气。

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,熵的绝对值,利用卡诺循环证明绝对零度不能达到。
