摘要
应用热力学理论以及费米积分的特性 ,导出理想费米气体焦汤系数的解析表达式 ,详细讨论了低温下费米气体的定压热容和焦汤系数 ,并阐明了费米气体的量子本性对焦汤效应的影响 .结果表明理想费米气体的焦汤效应为负效应 .
Using the characteristics of Fermi integral function and the theory of thermodynamics, an analytical expression of Joule Thomson effect (JTE) of ideal Fermi gas is derived. The properties of Joule Thomson coefficient and the specific heat at constant pressure of ideal Fermi gas in low temperature are discussed. The contribution of purely quantum nature of system on JTE is examined. It shows that JTE is negative.
