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.
