摘　　要：根据热力学理论,讨论了遵从推广的范氏方程气体的热容量,以及焦耳系数、焦汤系数的计算,应用v→∞时遵从推广的范氏方程气体趋于理想气体,表示出F,并由此导出内能U、压强P、埔S、烽H和吉布斯函数G,分析发现推广的范氏方程更苻合实际气体的情况。According to thermodynamic theory,discussed the heat capacity,Joule coefficient and Joule-Thomsen calculation of gas of Van der Waals on the Promotion of the equation To promote compliance with the application volume when the Van der Waals goes into the ideal gas.expressed free energy,and thus within the export to internal energy,entropy,and Gibbs function enthalpy,found that the promotion of Van der Waals gas equation was more in line with the actual situation.

关 键 词：范氏方程 焦耳系数 焦汤系数 范氏气体
