摘　　要：根据理想量子气体的粒子数和能量的密度 ,通过严格的理论推算 ,给出理想量子气体在高温低密度条件下非相对论和极端相对论能量 ;再由巨正则系综中能量和压强相对涨落的公式 ,采用合理的近似方法 ,给出巨正则系综能量和压强相对涨落的严格解 ,并将其与正则系综对比 。According to density of particle numbers and energy of perfect quantum gas ,by strict theoretical calculation ,the energy of non relativity and relativity about perfect quantum gas under high temperature and low density is given. Strict solution of relative fluctuation about grand canonical ensemble energy and pressure is derived from the formulae of relative fluctuation about grand canonical ensemble energy and pressure and adopting reasonable approximate method. In comparison with canonical assemblage, thermodynamic equipollence character and personal differences in the fluctuation of intensity quantity about two assemblage are totally revealed.
