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) 上求 Planck 分布...
Three different methods, among them the one considered by Boltzmann (Carnot cycle), lead to the expression ρ = ηTγ/( γ 1), where η is a constant. This result also appears naturally in the framework of general relativity for spacetimes with constant spatial curvature. Some particular ...
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. ...
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 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 ...

ステファン・ボルツマンの法則では、黒体の総放射強度 Eb が次の式で与えられます。Eb = s T4ここで、s はステファン・ボルツマン定数、T は黒体の絶対温度です。 ステファン・ボルツマン定数の値は、5.67x10-8 ...
The formula for Stefan-Boltzmann law is represented by the relation: F=σT4 where, F = energy flux T = temperature in Kelvin σ = constant = 5.67×10−8 J/(sm2K4) It is evident from the formula that by doubling the temperature of an object, the energy radiated per second per ...
