运用Dieterici状态方程讨论J-T效应，对J-T系数以Virial形式的Dieterici方程加以探讨，通过对CO2实际气体等焓膨胀的J-T系数及转换温度与Dieterici理论值比较发现，CO2实际气体的J-T系数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。

J-T effect is discussed by means of Dieterici state equation and J-T coefficient with Dieterici equa-tion in the form of Virial is explored. Based on the actual CO2 gas such as the expansion of the enthalpy of J-T coefficient and the transformation temperature and compared with Dieterici theoretical value, it has been found that there exists a small deviation between J-T coefficients and the transformation temperature and the theoreti-cal value, which can basically reflect the actual gas joule-Thomson various basic relationships, and can be ap-plied to general qualitative analysis of thermodynamics.
