The law of heat spontaneous transfer and the law of heat-work conversion are correspondence between positive energy spectrum(PES) and negative energy spectrum(NES).

具体分析了负能谱系统中“热”的自发传输规律和“热-功”转化规律。

The invention relates to a high efficiency heat engine having combined heat-work conversion process, especially an heat engine integrated with multiple working strokes and multiple working media.

本发明涉及带组合式热功转换过程的高效率热机，尤其是集成了多种做功冲程和多种工质的热机。

He observed when people were machining cannon barrels, a lot of heat was generated, and there was a lot of work done.

他发现人们在制作炮管时，会产生大量的热，同时有大量的做功。

Real refrigerators actually work with liquids that go into gases so use the latent heat of the liquid, so it doesn't really work like the Joule-Thomson expansion. So this is real.

液体变成气体来工作,以运用液体的潜热，所以这不是,真正像焦耳-汤姆逊膨胀一样工作,这是真实的气体，不像焦耳。

There's no change in them, and then we also looked at some at non-state functions, work and heat, and saw that those aren't zero going around a cycle. Of course you can do work in a cyclic process, and heat can be exchanged with the environment at the same time.

它们不会有变化，然后我们研究了,一些非态函数，功和热量，并看到,沿着循环行进一周的话,它们并不是零，当然你可以在,一个循环过程中做功，而同时热量可以在系统,与外界环境之间进行交换。

The discovery surveys done under the RCAHMW flying programme in extreme weather conditions - they carry out the work in the heat of summer too - mean "sometimes the story of Wales gets flipped on its head, " said Dr Driver.

In a vacuum, a conventional circuit breaker -- which measures heat across a load -- doesn't work, because there, there's less or no atmosphere there to draw the heat off, so a conventional circuit breaker would trip.
