热力学第二定律理论体系的讨论

热力学第二定律原有的两个理论体系都有明显的不足之处，为此，综全各种方法的优点，利用我们提出的简单物质可逆补热循环以及微分方程基本理论，简单明确地直接由热力学第二定律的开尔文表述推导克劳修斯等式、不等式，在推导过程中自然地引出绝对温度，得到热力学熵和增加原理，从而建立起热力学第二定律的新理论体系。

A discussion on theoretical system for the second law of thermodynamics

Two old theoretical systems for the second law of thermodynamics have obvious disadvantage.An alternate theoretical system for the second law is advanced.In the latter,the Clausius equality and inequality are derived from the Kelvin form of the second law and the absolute temperature is introduced in a very simple manner by use of a reversible cycle of a simple system,in which the heat is compensated for the external heat reservoirs.
