摘要： Using the improved brick-wall model, we have calculated the first quantum correction to the entropy of non-static black holes, Vaidya－Bonner black holes, due to the gravitational, electro-magnetic and neutrino fields. The result shows that both bosonic entropy and fermionic entropy are exactly proportional to the area of the event horizon. Thus, the entropy-area law still holds in such a non-static case.
