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.
先前已经表明，基于空间的出现和能量平衡关系来描述宇宙的演化更为常见。在此，我们研究由这样一个模型所描述的宇宙的热力学性质。我们表明，对于两个典型例子，热力学第一定律和广义热力学第二定律（GSLT）都得到满足，并且弱能量条件也得到满足。最后，我们检验当前模型的物理一致性。结果表明，对于这样一个宇宙存在良好的热力学描述。
