摘　　要：利用弯曲时空中标量粒子运动的Hamilton-Jacobin方程,研究动态Kerr黑洞周围时空中标量粒子的能量分布,得到了粒子的能量分布不仅与粒子的质量、角动量有关,还与黑洞的时空结构及视界的变化有关.给出了黑洞发生自发辐射的能量条件.Using Hamilton-Jacobin equation of scalar particles in curve space-time, the energy distribution of scalar particles in space-time of a non-static Kerr black hole is studied. We find that the energy distribution of scalar particles is not only depends on the mass and angular momentum of them, but also is related to the structure of space-time and the variations of event horizon of black hole. The energy condition for the occurrence of the spontaneous radiation is obtained.
