摘　　要：本文利用量子统计的方法推导玻色系统的热力学量的统计表达式,得到了玻色系统由巨配分函数表示的内能、熵、压强,并分别讨论了有外势和无外势影响下的巨热力势的表达式,给出了弱简并作用时玻色气体的内能形式。同时,将光子气体作为玻色气体的一个特例结合其特点,对光子气体的热性能进行研究,推导出普朗克公式,得到了光子气体的内能、热容量、焓、自由能、吉布斯函数的表达式。This thesis deduced the statistical expression of thermodynamic quantity in Bose system with methods of quantum statistics,and obtained the internal energy,entropy and the intensity of pressure in Bose system,which are indicated by grand partition function.The expression of grand thermodynamic potential with the influence of outside or not is also discussed.And we also give the form of internal energy of Bose gas under weak degeneration.The thermal properties of photon gas are studied as a special case of B...
