最近的研究给出了BTZ黑洞质量的热力学焓的解释和相应的Smarr公式。所有这些都是在三维（3D）广义相对论的背景下进行的。在本文中，我们扩展到一般的三维重力模型这样的解释。结果表明，直接推广是不可行的，需要一些额外的条件来保持Smarr公式和黑洞热力学第一定律。因此，BTZ黑洞热力学对一般的3D引力模型施加了一些约束，这些约束与所有以前的讨论是一致的。
Recent studies have presented the interpretation of thermodynamic enthalpy for the mass of BTZ black holes and the corresponding Smarr formula. All these are made in the background of three-dimensional (3D) general relativity. In this paper, we extend such interpretation into general 3D gravity models. It is found that the direct extension is unfeasible and some extra conditions are required to preserve both the Smarr formula and the first law of black hole thermodynamics. Thus, BTZ black hole thermodynamics enforces some constraints for general 3D gravity models, and these constraints are consistent with all previous discussions.
