摘　　要：计算出弱简并理想气体的化学势μ,与非简并理想气体和简并性理想气体的化学势μ比照发现,理想气体的化学势μ随温度T而减小,且是粒子数密度n(=N/V)的函数;结合所导出的多元系粒子的最概然分布,揭示了理想气体化学势μ的统计关联本质.The chemical potential of weak degenerate ideal gas is calculated and the most probable distribution of the multi-component system is deduced in this paper. The calculated chemical potential as a function of the temperature (T) and the particle density (n) is compared with the chemical potential of degenerate ideal gas and non-degenerate ideal gas. It is found from the comparison that the chemical potential of ideal gas decreases as the temperature (T) increases; the property of statistical relevancy about the ideal gas is expounded through the deduction and the comparison process.
