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) ...
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」Rrad (單位面積的輻射功率),..
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...
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.
(b)The Stefan-Boltzmann law can be written as In L = 4In T + In oA The student obtains a range of values for L and T and plots a graph of In L against In T.(i) Explain clearly how she could use this graph to obtain a value for o.(2)(ii)She realises that she cannot ...
Stefan's law (redirected fromStefan-Boltzmann law) Encyclopedia Wikipedia Stefan's law (ˈstɛfənz) n (General Physics) the principle that the energy radiated per second by unit area of a black body at thermodynamic temperatureTis directly proportional toT4. The constant of proportionality ...
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 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. ...
