摘　　要：基于非广延统计物理中的广义量子气体理论,研究极端相对论自由费米气体的非广延热力学性质,运用近似方法简化并给出总能、热容量、化学势的解析式,利用数值模拟得出这些物理量在高温、低温下具体的曲线,并且分析温度、极端相对论效应及非广延参数对系统热力学性质的影响机制.Basing on the generalized quantum gas theory in non-extensive statistical physics, thermodynamic properties of non-extensive Fermi gas under the condition of ultra-relativity are investigated, and using the approximate method, analytical expressions of energy, heat capacity and chemical potential of the system are given and simplified. Harnessing the numerical simulation, the curves of those thermody- namic properties are provided under the condition of the high temperature and the low temperature. In addition, according to those curves, the influential mechanism of temperature, the ultra-relativistic effect and non-extensive parameter of the system are analyzed.
