| 摘 要： | 研究有限重力场中弱简并理想费米气体的热力学性质.采用Thomas-Fermi半经典近似方法,从有限重力场中理想费米气体的状态密度出发,给出系统的化学势、内能和压强解析表达式,分析重力场对弱简并理想费米气体热力学性质的影响.结果表明,有限重力场的存在使弱简并理想费米气体热力学量出现一个附加的修正项.

| Abstract: | The study is on the thermodynamic properties of finite gravitational field weak degenerate ideal Fermi gas.Base on the Thomas-Fermi semiclassical approximation,after deriving the density of states of an ideal Fermi gas in finite gravitational field,the analytic formula of the chemical potential,internal energy and pressure under the condition of weak degeneration is obtained in this paper.The specific impact of the gravity field on the thermodynamic properties of weakly degenerate ideal Fermi gas is analyzed.The result showed that finite gravitational field has effect on the thermodynamic property of the system. |
