第二章建立狄塞尔热机循环的有限时间热力学模型。

In Chapter 2, we propose a finite-time thermodynamics model for a Diesel heat engine cycle.

为了接近卡诺效率，所涉及的过程，在热机循环必须可逆且涉及没有改变熵。

In order to approach the carnot efficiency the processes involved in the heat engine cycle must be reversible and involve no change in entropy.

引入两个内不可逆性参数，分别用于描述热机循环的内不可逆性和制冷循环的内不可逆性。

Two internal irreversibility parameters, the heat engine cycle and the refrigerator cycle were introduced to characterize the irreversibility inside the cycle.

We're building up to entropy and to engines, Carnot cycles, etcetera.

我们要研究，熵，热机，卡洛循环等概念。

And you know, you could have a reversible engine with lots and lots of steps, but you could always break them down into some sequence of adiabatic and isothermal steps.

你们知道，我们可以设计一个由，很多很多个,循环步骤的热机，但是总可以把它分割成,一系列的绝热,和等温过程。

Now what I want to do is put up a specific example of the cycle that can be undertaken inside here in an engine, and we can just calculate from what you've already seen of thermodynamics.

现在我想做的是,举一个例子,来具体说明热机内部的循环过程，同时我们可以利用热力学定律进行计算,看看热力学参量发生了什么变化。
