热量传递是一种复杂的现象,常把它分成三种基本方式,即导热、热对流及热辐射。生产和生活中所遇到的热量传递现象往往是这三种基本方式的不同主次的组合。应该指出,热量传递的基本方式虽然只有三种,但与生产和生活的各个领域密切相关的热量传递问题却是多种多样的,而且需要在认清其基本规律的基础上作进一步的探索才能获得较满意的结果。
热量传递(heat transfer): 物体被加热或冷却的过程也称为物 体的传热过程。凡是遵循传热基本规律的单元操作,到可以用 热量传递的理论去研究。

热量传递曲轴箱并散发热量。
This heat is transferred to the crankcase. Here the heat is dissipated.
在可逆过程中,火积是守恒的,不发生热量传递能力的耗散。
In reversible process, there is the entranspy conservation, that is, no loss of capability of heat transport.
原因是这不过是一个物理规律,描述了流体或者其他介质中粒子的热量传递。
The reason for that is basically physics of how heat is transported between particles in fluid, or actually any medium.
Adiabatic meaning there's no heat involved, and we're going to see how that differs from the isothermal expansion and compression.
绝热意味着没有热量的传递,我们将看到它,与等温过程的区别。
The boundary is impervious to transfer of heat like a thermos Anything that happens inside of the thermos is an adiabatic change because the thermos has no connection in terms of energy to the outside world.
边界不能传递热量,像热水瓶一样,热水瓶里发生的任何事,都是绝热变化,因为热水瓶与外部世界,没有能量方面的联系。
We're going to find other properties that do care about the history of the system like work, that you put in the system, or heat that you put in the system, or some other variables But you can't use those to define the equilibrium state.
我们还会发现其他一些,与系统的历史有关的性质,比如你对系统做的功,或者你向系统传递的热量,或其他的变量,但你不能用它们,来定义平衡态。
