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。
史蒂芬-波茲曼 定律 (低溫) Stefan-Boltzmann Law 實驗目的:量測熱物體的溫度T (300 ~ 400 K) 和其熱輻射的「輻射強度」R rad (單位面積的輻射功率),藉以驗證「史蒂芬-波茲曼定律」並求「史蒂芬常數」σ。 實驗儀器:熱輻射感應器 (Radiation Sensor)、熱輻射盒 (Thermal Radiation ...
