摘　　要：利用李立新和刘辽导出的黑洞视界附近的辐射态方程计算了约束在一个球形盒子中的自引力辐射体系(含有中心黑洞)的熵的上限,讨论了该体系的引力坍缩的合理模式,证明了这一坍缩过程是一个熵增加过程:在坍缩过程中,整个体系的熵的上限等于具有相同质量的黑洞熵,这一结果为黑洞熵的起源提供了。一个合理的解释。The entropy bound of a self-gravitating radiation system (SGRS) confined to a spherical box with a central black hole is calculated by using the modified equation of state of radiation near black-hole horizon ,which was derived by Li and Liu. A reasonable mode of the gravitational collapse of a SGRS is given, and the collapsing process is proved to be an entropy increasing process, throughout which the upper bound on the entropy of the whole system is equal to the entropy of the final black hole with the same mass as the system. In this way,a possible explanation for the origin of biackhole entropy is provided,which is an extension of this author's previous work.
