摘要
对低温气体作了简要分析,并以低温气体为工质,以低温下气体高精度三参数方程为基础,结合低温气体的特性以及热力学理论,导得低温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 low temperature gas has been given in this article. Using the fundamental equations of low temperature gas, the characteristics of theory of thermodynamics, analytical expression of Joule Thomson coefficient （JTC） of low temperature gas is derived in this paper.The properties of JTC and the specific heat at constant pressure of low temperature gas are discussed.It is shown that the low temperature gas is suitable for cryogenic refrigeration system.
