一种推导黑体温度变换的简易新方法

A new and simple way to deduce the blackbody temperature transformation

近一个世纪以来,对黑体相对论温度变换的讨论一直在进行着。其中最具代表性的变换是在上世纪六十年代,由R.N.Bracewell等人以从实验发现的3K宇宙背景辐射为基础、从与实验符合很好的Plank黑体辐射公式出发。

During the recent century, the blackbody temperature transfonnaton has always been discussed. The To most representative formula is T=T0/γ（1-βcosθ）, which was presented in different ways by R. N. Bracewell et al in 1960s based on 3K blackbody cavity radiation and Plank＇s blackbody radiation distributions which were all in agreement with experiments. But unfortunately, deducing the upper transformation was involved in a large number of complicated calculations. In this paper, according to Wien＇s displacement law and relativisitic Doppler effect, a new and simple method to deduce the relativistic temperature transformation of blackbody was presented.
