先前已经表明,根据空间的出现和能量平衡关系来描述宇宙的演化是更常见的。在这里,我们调查的热力学性质的宇宙所描述的这样一个模型。我们证明了两个典型的例子都满足热力学第一定律和广义热力学第二定律,并且满足弱能条件。最后,我们检查本模型的物理一致性。结果表明,这样的宇宙存在一个很好的热力学描述。
It has previously been shown that it is more common to describe the evolution of the universe based on the emergence of space and the energy balance relation. Here we investigate the thermodynamic properties of the universe described by such a model. We show that the first law of thermodynamics and the generalized second law of thermodynamics (GSLT) are both satisfied and the weak energy condition are also fulfilled for two typical examples. Finally, we examine the physical consistency for the present model. The results show that there exists a good thermodynamic description for such a universe.
