摘要
本文用统计热力学的方法讨论了实际气体,指出:在实际应用中会出现在某些条件下满足pV=nRT但不满足U=(T);绝对满足理想气体状态方程的气体一定满足焦耳定律。
This article discusses actual gas by means of statistical thermodynamics and draws two conclusions： （1） In actual application there will be some gas which meets pV =nRT relatively,but don＇t meet U = （T）. （2）The gas which meets the ideal gas equation absolutely will be bound to meet Joule＇s law.
