摘　　要：利用弯曲时空中标量粒子运动的 Hamilton Jacobin方程,研究带有电荷和磁荷的球对称动态黑洞周围时空中标量粒子的能量分布.得到了发生自发辐射的能量条件,它不仅依赖于黑洞的质量、电荷和磁荷,还与黑洞视界的变化有关,与视界附近的四维电磁势有关.Depending on the Hamilton-Jacobin equation of scalar particles in curve space-time,we study the energy distribution of scalar particles in space-time of a spherically symmetric non-static black hole with electric charges and magnetic charges. The energy condition for the occurrence of the spontaneous radiation is obtained. It not only depends on the mass, electric charges and magnetic charges, but also is related to the variations of black hole event horizon and the 4-D electromagnetic potential near the event horizon.
