The quantum state entropy of Schwarzchild-de Sitterblack hole cosmos horizon

采用由广义不确定关系得到的新的态密度方程 ,研究了Schwarzchild deSitter时空背景下黑洞宇宙视界的熵 .利用新的态密度方程 ,克服了用brick wall模型方法计算黑洞熵 ,在消除紫外发散需取截断的不完善之处 ,以此揭示了黑洞熵与其视界面积成正比这一内在联系 。

Using the new equation for density of states due to the generalized uncertainty relation, the entropy of Schwarzchild-de Sitter spacetime is discussed. By use of the new equation for density of states, it overcomes the shortcoming that on eliminating divergence the calculation of black hole entropy with brick-wall pattern needs a cut off. Thus, it gets the result of the direct proportion between black hole entropy and its horizon area, brings to light the relationship between Schwarzchild-de Sitter and its cosmos event horizon and makes clear that the black hole entropy is the entropy of quantum state near the event horizon.
