驻波的能量特点与普朗克黑体辐射公式

Standing Wave Energy Characteristics and Planck Blackbody Radiation Formula

在分析介质中驻波形成时波的能量特征的基础上,阐述了驻波中的波节数、振动方式数与谐振子数之间的对应关系,把两相邻波节之间的能量等效成谐振子的能量,从而使求解驻波的能量问题转化为求谐振子的能量问题,并以黑体空腔为模型的热辐射问题为例,采用了一种较为简明的方法推导出黑体辐射的瑞利-金斯公式和普朗克公式。

By analyzing standing wave formation of the energy characteristics in some medium,one explains the corresponding relationship among the wave-node number in the standing wave,the number of oscillator vibration mode and the number of harmonic oscillator.To make the energy problem in solving standing wave into the one in harmonic oscillator,the paper gives the equivalence for the energy between two-phase neighboring wave node and the resonance.The problem in blackbody cavity as a model of thermal radiation as an example,it adopts a more concise method to derive blackbody radiation Rayleigh-Kings Planck equation and the formula.
