斯特藩-玻尔兹曼定律（Stefan-Boltzmann law），又称斯特藩定律，是热力学中的一个著名定律，其内容为：一个黑体表面单位面积辐射出的总功率（称为物体的辐射度或能量通量密度）j*与黑体本身的热力学温度T（又称绝对温度）的四次方成正比。定律 即:其中辐射度j*具有功率密度的量纲（能量/(时间·距离²)），国际...

The meaning of STEFAN-BOLTZMANN LAW is a statement in thermal radiation: the total emissive power of an ideal black body is proportional to the fourth power of its absolute temperature.
Stefan-Boltzmann 定律Stefan-Boltzmann 定律提出:黑体的总发射功率 Eb 由以下公式计算出: Eb = σ T4 其中σ 是 Stefan-Boltzmann 常数, T 是黑体的绝对温度。Stefan-Boltzmann 常数的值是 5.67x10 -8 W/m2 K4 或3.3063 x 10-15 Btu/s.in2.F4。黑体辐射的光谱变化由 Planck 分布描述。在所有波长 (λ) ...

The Stefan-Boltzmann Law states that the magnitude of the radiation output of an object is directly proportional to the fourth power of its surface temperature. In other words, as the temperature of an object increases, the amount of radiant energy it emits increases rapidly. ...
Planck's law :The quantity is the radiated by a surface of area A through a in the frequency range .The Stefan–Boltzmann law gives the power emitted per unit area of the emitting body, To derive the Stefan–Boltzmann law, we must integrate over the half-sphere and integrate from 0 to...
