摘要翻译：
我们建立了固定数目的非相互作用玻色子在方盒势中的配分函数和基态占据率的递推关系，并确定了基态比热和粒子数的温度依赖关系。与Feynman统计力学教科书中忽略基态的特殊作用的早期理论相比，本文建立了一个适当的半经典处理，得到了正确的小T行为。结果与精确的量子力学处理进行了比较。此外，我们还导出了系统的有限尺寸效应。

英文摘要：
We set up recursion relations for the partition function and the ground-state occupancy for a fixed number of non-interacting bosons confined in a square box potential and determine the temperature dependence of the specific heat and the particle number in the ground state. A proper semiclassical treatment is set up which yields the correct small-T-behavior in contrast to an earlier theory in Feynman's textbook on Statistical Mechanics, in which the special role of the ground state was ignored. The results are compared with an exact quantum mechanical treatment. Furthermore, we derive the finite-size effect of the system.
