特殊相对论流体力学中的瑞利-布里渊谱
The Rayleigh-Brillouin Spectrum in Special Relativistic Hydrodynamics
摘要：
在本文中，我们计算瑞利布里渊频谱的相对论简单流体根据三个不同的版本可用于相对论方法的非平衡热力学。这些计算的结果是，Eckart的版本预测这样的光谱不存在。这为质疑其有效性提供了论据。剩下的两个结果，它们彼此不同，提供了一个有限的形式，这样的频谱。这就提出了一个相当有趣的问题，即这两个理论中哪一个更适合作为相对论性非平衡热力学的可能版本。答案显然需要对这一问题进行更深入的研究。
英文摘要：
In this paper we calculate the Rayleigh-Brillouin spectrum for a relativistic simple fluid according to three different versions available for a relativistic approach to non-equilibrium thermodynamics. An outcome of these calculations is that Eckart's version predicts that such spectrum does not exist. This provides an argument to question its validity. The remaining two results, which differ one from another, do provide a finite form for such spectrum. This raises the rather intriguing question as to which of the two theories is a better candidate to be taken as a possible version of relativistic non-equilibrium thermodynamics. The answer will clearly require deeper examination of this problem.
