The energy condition for the occurrence of the spontaneousradiation is obtained.
给出了带电蒸发黑洞发生自发辐射的能量条件。

Atom's motivated state in not stable, it inevitably disintegrate into the lower energy state, which makes the phenomenon of the spontaneousradiation.
原子激发态是不稳定的,其必然会自发地向低能级衰变,产生自发辐射现象。

We prepared broadband source of transducer system in fiber grating by analyzing characteristics of amplification spontaneousradiation spectrum and LD drive in erbium doped fiber.
