摘　　要：宏观引力系统,比如黑洞,与非引力系统在热力学方面很不一样,其态函数熵与温度本质上是量子的,没有经典对应,因此对应的热力学在一定意义上来说本质上也是量子的,这为探讨量子引力提供了一个重要窗口.本文综述讨论作者及其合作者近期一系列有关黑洞的高维推广黑膜(超弦/M-理论中的基本动力学客体)的热力学相、相变及相关的临界现象的工作,希望为建立M-理论的完整理论框架提供重要的非微扰信息.A macroscopic gravitational system such as a black hole differs significantly from a non-gravitational system in thermodynamics in that its state functions entropy and temperature are quantum mechanical in nature without a classical limit.As such its corresponding thermodynamics,to certain extent,is also quantum mecanical in nature and this provides a window for the study of quantum gravity.This article reviews the recent work of the author and his collaborators on the thermodynamical phases,phase transitions and the related critical phenomena of the black branes in string/M-theory（the basic dynamical building blocks of this theory）,the higher dimensional generalization of the black hole,in hope of obtaining important non-perturbative information for the complete formulation of M-theory.
