| 摘 要： | 运用van der Waals状态方程讨论焦汤系数和转换温度,通过对CO2实际气体等焓膨胀的焦汤系数及转换温度与van der Waals理论值比较发现,CO2实际气体的焦汤系和转换温度与理论值偏差不大,基本能反映实际气体的焦耳-汤姆逊的各种基本关系,可应用于一般热力学的定性分析。

| Abstract: | The Joule-Thomson coefficient and inversion temperature were discussed by means of the van der Waals equation of state.The Joule-Thomson coefficient for isenthalpic expansion of CO2 real gas and inversion temperature were compared with theoretical value of the van der Waals.It is found that the theoretical value between the Joule-Thomson coefficient of CO2 real gas as well as inversion temperature and the van der Waals equation of state is not quite deviated.The various basic relations for Joule-Thomson of real gas can be reflected basically,and the general qualitative analysis can be applied. |
