摘　　要：用弯曲时空的熵密度对黑洞熵进行了直接计算,避免了求解场方程的困难.由于熵密度在事件视界上是发散的,因此取截断因子来防止发散.结果表明黑洞的量子熵与黑洞表面积成正比.With the density of entropy of curved space-time,we have calculated black hole entropy directly, and avoided the difficulty of solving the field equation. Because the density of entropy is divergent on the event horizon, the cutoff factor was used to prevent divergences. The result we calculated is that the black hole entropy is proportional to the horizon area.

关 键 词：黑洞 熵密度 事件视界
