通过发出所谓的霍金辐射，黑洞会逐渐失去能量和质量。
By emitting this so-called Hawking radiation, a black hole would gradually lose energy and mass.
这个黑洞会因为辐射殆尽而最终蒸发掉。
Eventually the black hole radiates itself away - it evaporates.
另一种黑洞存在的标志是x射线辐射的随机变化。
Another sign of the presence of a black hole is random variation of emitted X-rays.
但是黑洞发出的霍金辐射非常弱以至于几乎无法探测。
Hawking radiation from black holes would be so weak as to be nearly undetectable, however.
给出了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 is obtained.
