摘　　要：讨论了弯曲时空中黑洞量子隧穿的时间.在假定了黑洞量子隧穿是一个瞬时过程的情况下,通过利用WKB法得出了有静止质量粒子的量子隧穿辐射谱.该辐射谱表明对于在黑洞视界处有静止质量粒子的出射也满足量子力学中的幺正性原理,支持Parikh-Wilczek的结论.结果的合理性表明,在黑洞视界处的量子隧穿过程可以看成是一个瞬时过程.The black hole barrier penetration time in a curved space time is discussed.By supposing that the tunneling process is an instantaneous process,we get an emission spectrum of massive particles with the WKB approximation method.This spectrum denotes that the emission of the massive particle near the horizon satisfies the unitary theory in the quantum theory,and supports Parikh-Wilczek＇s conclusion.It is seen from reasonableness of our result that the quantum tunneling in the event horizon of a black hole should be an instantaneous process.
