【摘要】 采用“ｂｒｉｃｋｗａｌ”模型研究了二维和四维带电黑洞的修正熵，得到了和用泛函积分计算一致的结果．对于极端黑洞，二维黑洞的修正熵为零，但四维黑洞的修正熵存在更高次的发散．更多还原

【Abstract】 The study of quantum correct entropy of the 2D and 4D charged black hole by “brick wall” model is reported.It is found that the results of this work are the same as those derived from the functional integral.The quantum correct entropy of the exetreme black hole is zero in 2D but divergent in 4D.更多还原
