论文摘要

在最近的一篇论文中(Coll {\ em等} 2019 {\ itClass。tastumgrav。} {\ bf 36} 175004)在本地热平衡中研究了II类Szekeres-Szafron解决方案的家族。在本文中,我们针对所有其他II类Szekeres-Szafron解决方案进行了类似的研究,而无需对称。分析了局部热平衡中的这些模型(常规模型),并获得了相关的热力学方案。特别是,我们专注于与状态的通用理想气体方程兼容的解决方案($ p = \ tilde {k}nθ$),我们在深度进行了两种明显的解释中分析了两个特定的热力学方案的选择:首先是当地的热量量中的一个普通温度,是一个普通的温度,是一种模型,是一个模型,第二个模型,第二个模型。上面的模型显示,在时空的广泛域中,在物理现实,内部能量和温度的阳性,内部能量和温度,能量条件和可压缩性条件上满足了一般必要的宏观宏观要求。

In a recent paper (Coll {\em et al} 2019 {\it Class. Quantum Grav.} {\bf 36} 175004) we have studied a family of Szekeres-Szafron solutions of class II in local thermal equilibrium (singular models). In this paper we deal with a similar study for all other class II Szekeres-Szafron solutions without symmetries. These models in local thermal equilibrium (regular models) are analyzed and their associated thermodynamic schemes are obtained. In particular, we focus on the subfamily of solutions which are compatible with the generic ideal gas equation of state ($p = \tilde{k} n Θ$), and we analyze in depth two notable interpretations that follow on from the choice of two specific thermodynamic schemes: firstly, as a generic ideal gas in local thermal equilibrium and, secondly, as a model having the homogeneous temperature of the FLRW limit. The models above are shown to fulfill the general necessary macroscopic requirements for physical reality (positivity of matter density, internal energy and temperature, energy conditions and compressibility conditions) in wide domains of the spacetime.
