摘　　要：利用广义不确定关系计算量子态数目,进而计算Vaidya-Bonner-de Sitter黑洞的熵。此方法与brick-wall模型相比,优点为不必引入截断因子,从而避免了发散问题。Using the generalized uncertainty relation,the number of quantum states was calculated, and the entropy of Vaidya-Bonner-de Sitter black hole was obtained.Compared with the brick-wall model, the divergence problem is removed without introducing any cutoff using this method.

关 键 词：黑洞 熵 广义不确定关系 BRICK-WALL模型
