| 摘 要： | 指出目前教科书和文献所用的热波长概念仅适用于非相对论性系统，而本文引进了普遍热波长的概念。由此可使理想量子气体的热力学函数表示成统一的简洁形式，并进一步揭示了热波长的物理内涵。另外还导出玻色－爱因斯坦凝聚温度和费米温度间的普遍关系。

| Abstract: | It is pointed out that the concept of thermal wavelength used in current literature and textbooks is only suitable for the nonrelativitic systems. The concept of general thermal wavelength is introduced. It makes the thermodynamic functions of an ideal quantum gas may be expressed in a unified compact form,and the physical connotation of the thermal wavelength is revealed further. Moreover,the general relation between the BEC critical temperature and Fermi temperature is derived. |
