摘要:
本文构建广义的f(R)引力即物质与曲率耦合的f(R)引力理论，在以动态表观视界为边界、其内部充满具有霍金温度的普通物质的FRW宇宙背景下，由广义f(R)引力的场方程可推导出广义热力学第二定律，并利用广义热力学第二定律对具体模型参数进行限制。
The generalized f(R) gravity with curvature-matter coupling is studied in this paper. The genera-lized second law of thermodynamics (GSL) can be given by considering the FRW universe filled only with ordinary matter enclosed by the dynamical apparent horizon with the Hawking temperature. Furthermore, as a concrete example, by utilizing the GSL, the constraints on the gravitational model are also discussed.
