We present a simple calculation of the Lorentz transformation of the spectral distribution of blackbody radiation at temperature T. Here we emphasize that T is the temperature in the blackbody rest frame and does not change. We thus avoid the confused and confusing question of how temperature transforms. We show by explicit calculation that at zero temperature the spectral distribution is invariant. At finite temperature we find the well-known result familiar in discussions of the 2.7 K cosmic radiation.
我们给出了温度为(T)时黑体辐射光谱分布的洛伦兹变换的简单计算。在此我们强调,(T)是黑体静止参考系中的温度且保持不变。因此,我们避免了关于温度如何变换这一令人困惑的问题。通过显式计算,我们表明在零温度下光谱分布是不变的。在有限温度下,我们得到了在讨论(2.7K)宇宙辐射时常见的熟知结果。
