球对称动态黑洞Dirac场的熵的再讨论

Further discussion on the entropy of Dirac field in spherically symmetric non-static black hole

采用新的广义乌龟坐标变换,利用薄膜brick_wall模型.讨论了球对称动态黑洞Driac场的Hawking温度和熵,由于k因子的变化,使Hawking温度有一定影响,而截断因子不再因时空结构不同而异,变得与稳态情况相同.

A new general tortoise coordinate transformation is used with the thin film brick-wall model. We further discuss the Hawking temperature and the entropy of Dirac field in spherically symmetric non-static black hole. The cut-off parameter does not vary for different time-space structure, and it is reduced to that of the stationary cases.
