现在是可逆绝热过程，因此这里有一个关系式，我相信你们还记得。
Now, this is a reversible adiabatic path, so there's a relationship that I'm sure you'll remember.
可见可逆绝热过程都是熵不变的过程，可以把这种过程叫做等熵过程。
It follows that every reversible adiabatic process is one of constant entropy, and may be described as isentropic.
这里的末态温度,与经过可逆绝热过程,到达相同压强的末态温度相比哪个比较高呢？
T2 Is the temperature T2 in this process smaller or larger than if I were to do the process reversibly with the same endpoint pressure.
以经典理想气体为工质的卡诺热机循环由两个等温和两个绝热过程构成，热机可逆时，它的效率为最大。
A cyclic thermodynamic heat engine, which combines adiabatic and isothermal processes and consists of classical ideal gas as working substance, runs most efficiently if it is reversible.
绝热过程可以是可逆的，也可以不是，我们可能会在下一次或下下次课上，研究这个问题。
Adiabatic can be either reversible or not, and we're going to do that probably next time or two times.
模型考虑了燃烧过程气缸壁与环境间的热漏、循环工质在绝热过程中的内不可逆性以及循环时间的影响。
Our model considers heat leak between cylinder wall and environment in combustion process, internal irreversibility of cyclic working fluid in adiabatic processes, and cycle time.
