摘　　要：采用半经典(Thomas-Fermi)近似方法,研究了有限重力场中广义测不准原理下理想费米气体的性质.得到了内能和定容热容在低温情况下的解析表达式,同时以铜电子气为例进行了具体模拟计算,并与不考虑广义测不准原理时的结果进行了比较分析,讨论了了广义测不准原理对体系性质的影响.T he properties of ideal Fermi gas are studied under the finite gravitational field of generalized uncertainty principle . The internal energy and the constant volume heat capacity in which the analytical expressions under the condition of low temperature are given . Meanwhile , the specific simulation calculation of copper electron gas is given as an example . T he effects of the generalized uncertainty principle on the properties of the systems are discussed .
