【Abstract】 The geometry of the neighborhood nearby the horizon is similar to the Rindler metric. The entropy of the scalar field and Dirac filed under the background is computed. The result S∝A is naturally obtained, which applies to a large class of black holes. The extreme black hole is investigated and it is pointed out that the topological entropy only has the classical meaning and is not a quantum viewpoint.更多还原
