And the cycle it's going to undertake is called a Carnot cycle, and it works the following way: we're going to do pressurevolumework.
它的循环过程，叫做卡诺循环，过程如下：，这是个压强体积系统。

I also want to assume for our present purposes that there's only pressurevolumework going on, which is to say I want to put pdV p dV in here minus p dV for dw.
同时假定,对于我们目前的目的而言，只有压强做功这就是说,我要把这里的dw替换为负。

Work by a pair of cavity mesh with each other in motor driver of rotor, next at high speed, and between the volume is constantly changing, so as to constantly pressure increase pressure condensed.
