热力学第二定律

There is another principle, independent of the first law and not derivable from it, that is the second law of thermodynamics.

在热力学第一定律之外还有其它定律制约着热功转换的效率。那就是热力学第二定理。

Energy, work, heat and the first law of thermodynamics

第二章：能量，功与热力学第一定律

Clearly, a refrigerator, which is a physical system must obey not only the first law but the second law of thermodynamics as well.

很明显，冷冻机是一种物理系统，因此它不仅必须遵从第一定律，也必须遵从热力学的第二定律。

The first and second law of thermodynamics, as the universal rules in the nature, can be invoked to describe the energy dissipation.

热力学第一定律和第二定律作为自然界普遍适用的规律，能够用来描述能量耗散。

Cycle process, efficiency of heat engine, refrigerator coefficient, Carnot cycle, thermodynamic second law and its physical meaning.

循环过程，热机效率，致冷系数，卡诺循环；热力学第二定律及其物理意义。

Starting from the graphs of P-V and T-S and the second law of thermodynamics, and on different aspects and with different methods, this article studies the maximum value of the efficiency of heat engine in the process of arbitrary cycles, and presents the conclusion that the efficiency of the heat engine in Carnot cycle is the greatest among all arbitrary cycles.

卡诺定理给出了热机的循环效率极大值问题。由P-V图、T-S图、热力学第二定律出发，从不同的角度，采用不同的方法，对任意循环过程的热机效率极大值问题进行了研究，证明了任意循环过程热机效率以卡诺循环的热机效率为最大极限值的结论

The application of Clausius inequality is mainly introduced during the teaching; however, the application of the verbal expression of the Second Law of Thermodynamics was less mentioned.

热力学第二定律是用来判断过程的方向和限度的，在教学中主要介绍Clausius不等式的应用。

"The concept, first propose d in 1850 by the German physicist Rudolf Clausius (1822-1888), is sometimes presented as the second law of thermodynamics,"

&熵的概念是德国物理学家克劳修斯(Rudolf Clausius，1822～1888)于1850年提出的，孤立系统的熵上能增加不能减少，有时也被说成是热力学第二定律。&

The chemist Dalton first gave a proof of the existence of atoms and the engineer Sadi Carnot first gave a proof of the Second Law of Thermodynamics.

化学家道尔顿最先证明了原子的存在，工程师萨迪。卡诺第一个证明了热力学第二定律。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
