摘　　要：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.Using the improved brick-wall model, the writers of the article have made some researches in the contribution made by the high spinning gravitation field to static ball-symmetry black hole entropy. The research shows that in the static ball-symmetry black hole, the quanta entropy of the gravitation field in whitch the spinning is 2 is still in direct proportion to the horizon. When the same truncatin genes as theose in scalar guantity field are selected the quanta entropy is two times in scalar quantity field, and four-sevenths of those in Dirac field.
