实际气体的玻尔兹曼因子方程

将玻尔兹曼分布律应用于实际气体紧靠容器壁处,厚度为气体分子有效作用距离s的边界区域保守力场中,用边界区域界面自由能作为状态参量之一,推导出实际气体的玻尔兹曼因子方程。进而应用该方程导出了理想气体物态方程、非理想气体物态方程、气体体系边界区域热力学函数和焦耳-汤姆逊效应的新解析。用与著名的范德瓦尓斯方程、维里方程对比分析的方式进一步论证了:玻尔兹曼因子方程不仅形式简单、物理意义明确,而且比范氏方程、维里方程更能如实地描写实际气体在各种压强条件下的自然状态、更具合理性与普遍性。

Boltzmann Factor Equation of the Real Gas

Applying Boltzmann distribution law on a conservative force field of the real gas close to the wall of the container which thickness is equal to S of a gas molecular effective action distance,and using the interfacial free energy of the gas on the border region as one of the state parameters of the gas,Boltzmann factor equation of the real gas is derived.Further,from this equation,the equation of state of the gas of the perfect and imperfect,the thermodynamic functions of the gas on the border region and the new analysis of Joule-Thomson effect are obtained.Then compare with the well-known Van Der Waals equation and virial equation,it is proved that Boltzmann factor equation of the real gas obtained here,is really not only form-simple and physical-meaning-clear but also more reasonable and universal than Van Der Waals equation and virial equation in depicting the real gas state in various pressure conditions.
