摘　　要：目的解决黑洞熵的发散问题.方法利用广义不确定关系计算量子态数目,进而计算G-H-S黑洞的熵.结果此方法不必引入截断因子,就避免了熵的发散问题,而且得到了黑洞熵与其视界面积成正比的结果.结论利用广义不确定关系计算黑洞的熵,不必引入截断因子,就可避免熵的发散问题.Objective To solve the divergence of black hole＇s entropy. Methods Using the generalized uncertainty relation, the number of quantum states is calculated, and the entropy of G-H-S black hole is obtained. Results The divergence is removed by using this method without any cutoff, meanwhile the conclusion that the entropy of a black hole is proportional to the area of its event horizon is got. Conclusion Using the generalized uncertainty relation to calculate the entropy of a black hole, the divergence will be resolved.
