摘　　要：本文研究三维理想费米气体的热力学性质,应用局域密度近似(LDA)方法求出处于幂函数型外势下的三维理想费米气体的总能E,费米能,高低温极限下的化学势和热容量C的表达式。讨论外势对三维理想费米气体热力学性质的影响。并对自由费米气体和外势下理想费米气体的热力学性质进行比较。Thermodynamic properties of an Ideal Fermi Gas are studied basing on the local density approximation. The total energy E,Fermi energy,chemical potential and heat capacity C in the high-and low-temperature approximations in a Three-Dimensional Space trapped in a generic power-law potential are derived.The influence of thermodynamic properties of an Ideal Fermi Gas by the power-law potential are discussed.And the thermodynamic properties of a freedom Fermi Gas are compared with an ideal Fermi Gas trapped in a generic power-law potential by using the list.
