摘要:  建立了一个简单的模型来描绘空腔辐射中腔壁与辐射场的能量交换,由此可以得到空腔辐射平衡场能谱的性质,基尔霍夫定律,以及空腔与黑体的关系.

关键词: 空腔辐射, 黑体辐射, 基尔霍夫定律

Abstract: A simple model is introduced to depict the energy exchange between the cavity wall and the radiation field in the establishment of cavity radiation. Some conclusions are discussed concerning the property of the equilibrium field, Kirchhoff's law of thermal radiation, and the relation between the cavity and a black-body.

Key words: cavity radiation, black-body radiation, Kirchhoff's law of thermal radiation
