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.-
