| 摘 要： | 采用薄膜brick-wall方法,计算了动态整体单极黑洞Dorac场的熵.结果表明,通过对时间依赖的截断因子作适当的选择,仍可获得黑洞熵与其视界面积成正比的结论.还发现当黑洞退化为静态时,与已有的结果是吻合的.

| Abstract: | The entropy of the Dirac field in black hole with an global monopole is calculated, using the thin film model, which is based on the brick wall method. The conclusion that black hole entropy is proportional to its horizon area can still be applied by regulating the cutoff, which is time dependent here. Moreover, the result is coincident with the one of static black hole. |
