Taub-NUT黑洞的熵

Entropy of Taub NUT Black Hole

用ｂｒｉｃｋｗａｌ模型计算了ＴａｕｂＮＵＴ黑洞的自由能和熵，并分析了其不存在超辐射效应的原因．通过调整ｂｒｉｃｋｗａｌ的距离。

By using the brick wall method,we calculate the free energy and the entropy of Taub NUT black hole,and analyse the reason why there is no superradiant effect.Through adjusting the distance of the brick wall,we obtained the area formula of the entropy which satisfy the second law of thermodynamic.
