论文摘要
在一般相对论的几个可能的扩展中，标量调整理论是最受欢迎的，原因是多种原因。由于对重力的量子描述尚未正确表述，因此对引力理论的理解一直不完整，直到研究热力学和流体重力方面，这提供了一种理解重力理论的替代观点。在这篇综述中，我们以严格而简洁的方式研究了这些特征（热力学和流体重力类比），以表达标量调整的重力，这在我们最近的作品中已经揭示了。此外，已在动作级别以及从热力学和流体 - 雷神对应的角度上以明确的方式探索了共同连接的框架（\ textit {i.e。}是否具有物理上相等的两个框架）。
Out of several possible extensions of general relativity, the scalar-tensor theory is the most popular for several reasons. Since the quantum description of gravity is yet to be formulated properly, the understanding of a gravitational theory remains incomplete until the study of thermodynamic and fluid-gravity aspects, which provides an alternative viewpoint to understand the gravitational theory. In this review, we study these features (thermodynamics and the fluid gravity analogy) in a rigorous and yet in a concise manner for the scalar-tensor gravity, which has been revealed in our recent works. In addition, the issue of conformally connected frames (\textit{i.e.} whether the two frames, which are conformally related are physically equivalent) has been explored in an explicit manner at the action level as well as from the viewpoint of thermodynamics and fluid-gravity correspondence.
