高自旋场对静态球对称黑洞熵的贡献

利用改进后的brick wall模型，研究具有高自旋的引力场对静态球对称黑洞熵的贡献.结果表明：在静态球对称黑洞中，自旋为2的引力场的量子熵仍与视界面积成正比.当选择与标量场相同的截断因子时，其量子熵为标量场的两倍，为Dirac场的4/7. 关键词： 黑洞熵 brick wall模型 自旋场 Teukolsky型主方程

The contribution of the high spinning gravitation field to the static black hole entropy with spherical-symmetry

Using the improved brick-wall model,the writers of the article have made some r esearches in the contribution made by the high spinning gravitation field to sta tic ball-symmetry black hole entropy. The research shows that in the static bal l-symmetry black hole, the quanta entropy of the gravitation field in whitch th e spinning is 2 is still in direct proportion to the horizon. When the same trun catin genes as theose in scalar guantity field are selected the quanta entropy i s two times in scalar quantity field, and four-sevenths of those in Dirac field .
