空腔辐射中辐射压强与辐射能量密度之间关系

The Relation between Radiate Pressure and Radiate Energy Density in Cavity Radiation

统计物理学中,在推导空腔辐射的u(T)=αT4公式和求辐射场的熵公式时,两次都用到了辐射压强与辐射能量密度两者之间的关系.本文从能量守恒的角度对两者之间的关系进行分析和推证.

In statistical physics, when deriving the equation u（T） = φT^4 for cavum rad for radiation this paper w eld＇ s entropy, both use the relationship between rediation pressure and ra use the law of conservation of energy to analyze the relationship. iation and the equation diation energy density.
