在最近的一篇论文中，Pennisi和Ruggeri（Ann Phys 377：414-445，2017）。 https://doi.org/10.1016/j.aop.2016.12.012 提出了耗散多原子相对论气体的因果双曲模型。封闭是使用最大熵原理获得的分布函数的广义矩，在经典的情况下，取决于一个额外的连续变量表示的能量的分子的内部模式;这使得理论考虑到平移模式和内部模式的分子之间的能量交换。封闭性取决于一个与气体自由度有关的参数。本文证明了场方程在奇异极限下收敛于Liu等（AnnPhys 169：191，1986）用单原子气体相对论热力学扩展理论得到的系统。
In a recent paper Pennisi and Ruggeri (Ann Phys 377:414–445, 2017. https://doi.org/10.1016/j.aop.2016.12.012 ) proposed a casual hyperbolic model for a dissipative polyatomic relativistic gas. The closure was obtained using the maximum entropy principle for the generalized moments of a distribution function that, as in the classical case, depends on an additional continuous variable representing the energy of the internal modes of a molecule; this permits the theory to take into account the energy exchange between translational modes and internal modes of a molecule. The closure depends on a parameterthat is related to the degrees of freedom of gas. In this paper it is proven that in the singular limit forthe field equations converge to the system obtained by relativistic extended thermodynamics theory of monatomic gas by Liu et al. (Ann Phys 169:191, 1986).
