| Abstract: | The properties of a weakly interactlng Fermi gas in homogenous gravitational field are studied when the temperature is higher than Fermi temperature,based on the local-density approximation(LDA).The general analytical expressions of several important thermodynamic quantities are derived and the rules of distribution of particle-number density and energy density of the system are analyzed.Both of systems in homogenous gravitational field with and without internal interactlons are compared.The effects of gravitational field and inter-particle interactions on properties of Fermi gas are discussed. |
