【Abstract】 The generalized uncertainty relation is considered in the calculation of black hole entropy. Using the WKB approximation, the scalar field entropy of the horizon of the Vaidya black hole is calculated directly. The result is that the black hole entopy is proportional to the horizon area; the difference from the brick wall model is that present result is convergent without any cutoff.更多还原
