| 摘 要： | 用在brick模型基础上发展起来的membrane模型 ,计算了缘于任意自旋场的非静态黑洞———Vaidya黑洞的自由能和熵。结果表明 ,玻色子场 (自旋s =1,2 )和费米子场 (自旋s =1/2 )的熵都恰好与黑洞的视界面积成正比 ,这与静态和稳态的情况相同。而且 ,玻色子和费米子场的熵具有相同的形式 ,二者相差一个系数

| Abstract: | Using the membrane model which is based on brick-wall model, we calculated the free energy and entropy of non-static black hole, Vaidya black hole, due to arbitrary spin fields. The result shows that both the entropy of Bosons field(spin s=1,2) and that of Fermions field(spin s=1/2) are exactly proportional to the event horizon area. This is just same as the static and stationary case. Furthemore, the entropies of Bosons and Fermions have similar form. There is only a different coefficient between them. |
