| 摘 要： | 空窖内的平衡辐射可看作光子气体,本文使用玻色分布,推导出了光子气体的碰壁数表达式。为了显示此碰壁数表达式的应用价值,还使用它导出了斯特藩-玻尔兹曼定律,这是与教材中斯特藩-玻尔兹曼定律推导方法不同的另一简单方法。

| Abstract: | Equilibrium radiation in a cavity can be regarded as a photon gas.In this paper,Bose distribution is used to deduce an expression for the number of collisions between photons and the wall.To illustrate the importance of the expression,it is applied to deduce the Stefan-Boltzmann law,which provides a simple alternative approach that differs from derivation methods in textbooks. |
