摘　　要：有质量引力理论作为修正引力理论之一,对探究宇宙加速膨胀,以及解释暗能量和暗物质问题等有重要意义。研究了在常规相空间中de Rham-Gabadadze-Tolley(dRGT)有质量引力下球对称黑洞的热力学第一定律、热力学第二定律与弱宇宙监督假设是否成立;并通过图像探究熵的微分变化量随事件视界r_(d)变化的影响,以及与dRGT黑洞无量纲自由参数α,β与引力子质量对该图像的影响。在研究过程中,通过引入标量粒子的能量-动量关系,来验证黑洞热力学第一定律是否成立,通过观察事件视界对熵的微分变化量的影响,来验证黑洞热力学第二定律是否成立。研究发现,黑洞在吸收粒子的同时,其视界半径始终存在,从而使奇点始终没有裸露出来。结果表明,在dRGT有质量引力下球对称黑洞的热力学第一定律,热力学第二定律与弱宇宙监督假设均成立。As one of the revised gravity theories,the theory of mass gravity is of great significance for exploring the accelerated expansion of the universe and explaining the problems of dark energy and dark matter.In this paper we study whether the first law of thermodynamics,the second law of thermodynamics and the weak cosmic supervision hypothesis are valid for the spherically symmetric black holes under de Rham-Gabadadze-Tolley(dRGT)mass gravity in conventional phase space.The influence of the differential change of entropy with the change of event horizon r_(d),and the influence of dimensionless free parametersα,βand graviton mass related to dRGT black hole on the image are explored.In the research process,the first law of black hole thermodynamics is verified by introducing the energy-momentum relationship of scalar particles,and the second law of black hole thermodynamics is verified by observing the influence of event horizon on the differential change of entropy.The study finds that the black hole absorbs particles at the same time,its event radius always exists,so that the singularity is never exposed.The results show that the first law of thermodynamics,the second law of thermodynamics and the weak cosmic supervision hypothesis are valid for the spherically symmetric black holes under dRGT mass gravity.
