【摘要】 计算了ＮＵＴ－Ｋｅｒｒ－Ｎｅｗｍａｎ黑洞视界的高斯曲率、横向周长和极向周长，并讨论了这类黑洞的热力学性质．结果表明ａ，ｌ的耦合项影响到黑洞视界几何，而对黑洞热力学性质无影响更多还原

【Abstract】 The Gaussian curverture,transverse and polar circumferences are calculated for the event horizon of NUT Kerr Newman Black Holes.The thermodynamical properties of this kind of Black Holes are also discassed.The rusults show that the geometrical property of the Black Holes horizon is affected by the coupling term of a l ,but their thermodynamical properties are not be affected.更多还原
