摘　　要：对Redlich-Kwong气体作了简要分析,并以Redlich-Kwong气体为工质,应用Dieterici气体的特性以及热力学理论,导得Redlich-Kwong气体焦汤系数的解析表达式,并计算了焦汤系数.A brief analysis of the Redlich - Kwong gas is given in this article. Using the fundamental equations of Redlich - Kwong gas, the characteristics of theory of thermodynamics, an analytical expression of Joule Thomson coefficient （JTC） of Redlich - Kwong gas is derived. The properties of JTC and the specific heat at constant pressure of Redlich - Kwong gas are discussed. It is shown that the Redlich - Kwong gas is suitable for cryogenic refrigeration system.
