Demianski-Newman黑洞的热性质及广义Bekenstein-Smarr公式

THE THERMAL PROPERTY OF DEMIANSKI-NEWMAN BLACK HOLE AND THE GENERALIZED BEKENSTEIN-SMARR FORMULA

对于Ｄｅｍｉａｎｓｋｉ－Ｎｅｗｍａｎ（Ｄ－Ｎ）黑洞，同样存在在外视界处温度为Ｔ＋的Ｈａｗｋｉｎｇ辐射和在内视界处温度为Ｔ－的Ｈａｗｋｉｎｇ吸收，其形式与Ｋｅｒｒ－Ｎｅｗｍａｎ（Ｋ－Ｎ）黑洞相似．根据Ｄ－Ｎ黑洞中参数ｌ的一些性质，得到了与参数ｌ有关的广义Ｂｅｋｅｎｓｔｅｉｎ－Ｓｍａｒｒ（Ｂ－Ｓ）公式．对比Ｋ－Ｎ黑洞的Ｂ－Ｓ公式，可以推测ｌ一方面与转动效应有关，另一方面又能产生势场，可能是与自族有关的某种荷．

As to Demianski-Newman black hole,there are Hawing radiation with the temperature T+ of the outside horizon and Hawking absorption with the temperature T_ of the inside horizon,and the form is similar to that of Kerr-Newman black hole. A generalized Bekenstein-Smarr formula is used which contains the parameter l after considering the property of l. According to the Bekenstein-Smarr formula of Kerr-Newman black hole, it can be inferred that the parameter l is related to rotation effect and that it can generate potential field. Therefore, parameter l may be some charge concerning spin.
