| 摘 要： | 用解析的方法分析了二维自由理想玻色气体的热力学性质,结果表明,在没有外势约束的情况下,二维理想玻色气体不能形成了玻色--爱因斯坦凝聚.同时讨论了在强简并和弱简并两种情况下二维自由理想玻色气体的热容、熵和压强.在弱简并情况下,二维自由理想玻色气体的热力学性质趋于经典情况.

| Abstract: | The thermodynamic characteristics of the two-dimensional idea Bose gas have been studied by using approximate analytic calculations. The result shows that there is no Bose-Einstein condensation without external trap. The capacity entropy and pressure are studied under strong degeneroy and weak degeneroy. In the case of weak degeneroy, the thermodynamic characteristics of the two dimensional ideal Bose gas tend to be that of classical condition. |
