摘要
本文把液体系统中的排斥势作为相互作用势的主要部分,吸引势作为微扰,由微扰方法导出计算潜热的有关公式,给出分子相互作用势,就可由这些公式求得潜热与温度的关系,为工程上的计算提供了理论依据。
This paper points out that in liquid the molecules that acttract each other is much smaller than that repel each other. A expansion on the heat of vaporization has been dirived by perturbation theory.If the interactions in liquid are known,we can transform the expansion into a relation between the heat of vaporization and the temperature, for calculation of the heat of vaporization has been afforded a theoretic basis in engineering.
