摘　　要：利用赝势法求出无外势时低温、低密度量子费米气体的化学势、压强、熵、内能和定容热容等物理量的解析表达式,探讨了粒子间相互作用对系统低温性质的影响。The weakly interaction universally exists in actual quantum gases,the analytical expressions of chemical potential,pressure,trophy and heat capacity at a constant volume for actual quantum gases in the absence of external potential are derived using total energy deduced by pseudo potential method,then based on the derived expressions,the effects of inter-particle interaction on the properties of Fermi gas systems are discussed.

关 键 词：费米气体 弱相互作用 赝势法 低温
