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) 上求 Planck 分布定律的积分可给出 Stefan-Boltzmann 定律。
Thermodynamics arguments have been employed to derive how the energy density ρ depends on the temperature T for a fluid whose pressure p obeys the equation of state p = (γ 1)ρ , where γ is a constant. Three different methods, among them the one considered by Boltzmann (Carnot cycle),...
The locus of the maximum spectral radiance for a given temperature is a line given by the Wien displacement law: (2)λmax=2897.7T The fundamental equation of IRT relates the irradiance Ncam (i.e., spectral radiant power incident on a surface per unit area) received by an infrared camera ...
