略论热力学方法在科研和理论工作中的作用

本文讨论了封闭简单理想气体体系,只作体积功的可逆过程。应用热力学方法导得的公式中,把难测的物理量可转变为易测的物理量(如温度、压力、体积等)来求得,反之亦然。从而使科研工作化难为易,并将测定的数值上升为理论,提高科研水平。还论证该体系,分别由热力学第一定律和第二定律开始,用热力学方法可得到殊途同归的效果,这对理论研究工作也极重要。

On Thermodynamic Method in Scientific and Theoretical Research

Discussed is a simple closed system of an ideal gas regarded as reversible process,in which only work of volume expansion is dene.In the same formula derived from thermodynamic theory, some physical quantities difficult to measure are changed into easy (such as temperature,pressure,volume) and vice versa. In scientific research, it is very helpful to turn difficulties into convenience, the measured data will be raised to theory,improving its level. It is also proved that starting with the first and second laws of thermodynamics, the system under discussion will give the same results via different routes, which is very important to theoretical research work.
