低温热源的温度又是多少?
高温热源的温度是多少?
任何有长期历史价值的物品都应收藏在远离热源的地方。
Anything with long-term value should be housed away from heat sources.
In principle, this value, this efficiency, can approach 1 as the low temperature approaches absolute zero.
这个值,效率,当低温热源的温度1,是据对零度时可以达到一。
And then there's a cold reservoir T2 at some lower temperature T2.
另外有一个冷的热源,温度为。
And we had the similar statement by Kelvin about the heat engine that required that some heat gets dumped into a cold reservoir in the process of converting the heat from the hot reservoir into work.
相同的陈述,同样的有开尔文表述:,把热量完全从高温热源,转移至低温热源的过程中,必然有功的输出。
