A Vaidya Bonner black hole in De Sitter space is discussed. This paper gives the solution of the Klein Gordon equation near the event horizon, from which one can get both the Hawking temperature and the formula of thermal spectrum.

• 讨论了DeSiter时空背景中的Vaidya－Bonner黑洞，给出了Klein－Gor－don方程在黑洞视界附近的渐近解，得到了Hawking辐射温度和热谱公式
