摘要： 根据欧拉-麦克劳林（Euler-MacLaurin）公式，导出有限理想量子气体的热力学量表达式，揭示系统尺度和边界形状对其性质的影响．结果表明，有限尺度效应导致了一系列与热力学极限条件下不同的性质特征，如系统的非广延性和压强的各向异性等．

Abstract: Based on the Euler-MacLaurin formula, the expressions of thermodynamic quantities of a finite-size ideal quantum gas are derived and the effects of the size of the system and the shape of the boundary are revealed. It is shown that the finite-size effects result in several novel characteristics such as the non-extensively of the system, the anisotropy of the pressure, and so on, which are different from those obtained under the thermodynamic limit condition.
Key words: ideal quantum gas, finite-size effect, thermodynamic property
