摘要: 利用改进后的薄膜brick-wall模型，计算了动态广义球对称含荷黑洞Dirac场的熵.按薄层模型的观点，在视界附近薄场上的熵就是黑洞的熵.计算结果表明所得到的黑洞熵与其视界面积成正比.

Abstract: Using the improved brick-wall film model， we calculated the entropy of Dirac field in a generalized non-stationary spherically symmetric black hole with charge. From the point of view of the model， these entropies are nothing but the entropy of the black hole. The result showed that this entropy is proportion to the area of event horizon.
