球对称带电蒸发黑洞发生自发辐射的能量条件

The Energy Condition for the Occurrence of the Spontaneous Radiation of Spherically Symmetric Non-static Black Hole

利用弯曲时空中标量粒子运动的HamiltonJacobin方程,研究球对称动态黑洞周围时空中标量粒子的能量,得到了粒子的能量不仅与粒子的质量有关,还与黑洞的时空结构及视界的变化有关.给出了带电蒸发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 of scalar particles in space-time of spherically symmetric non-static black hole is studied. We find that the energy of scalar particles is not only depends on the mass of it, 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.
