一般球对称动态黑洞中Dirac场的熵

The entropy of dirac field in general spherierically symmetric non-staic block hole

采用乌龟坐标变换,在视界面附近把Dirac场方程化成波动方程,得到黑洞的辐射温度.用薄膜brick-wall模型计算黑洞的熵,结果表明熵与视界面积成正比,熵的表达式与静态或稳态情况一样简单.

Using the tortoise coordinate transformation and changing the Dirac field equation to wave equation near the vision interface, the radiation temperature of the black hole is gotten. The black hole＇ s entropy is also calculated from the film brick-wall model. The results indicate that the entropy is in direct proportion to the vision interface area and its expression form is as simple as the static or steady state is.
