Quantum entropy of the general non-stationary black hole with charges
动态广义球对称含荷黑洞的量子熵

The quantum state number and free energy of the scalar field at the horizon of general non-stationary black hole with charges are calculated and the result shows that the entropy of black hole is proportional to the event horizon area. This implies that the black hole entropy is just identical to the entropy of the quantum field on the event horizon. Taking into account the effect of the generalized uncertainty principle on the black hole entropy and adopting the 2-D membrane model, the divergence in the brick-wall model is removed, without any cut-off,and the little mass approximations appear in the brick-wall model and the thin film model are removed. Calculating the scalar field on the 2-D membrane outside horizon by using progression method we obtained some interesting results.
