摘　　要：把对动态黑洞量子热效应的研究推广到用(t,r)坐标描述的时空,采用了既不同于稳态又不同于以超前Eddington坐标描述的动态时空的乌龟坐标变换.在考虑Hawking蒸发影响的情况下,得到了De Sit-ter时空背景中具有整体单极蒸发黑洞的温度、视界位置.进一步分析表明Hawking辐射温度是坐标尺度变换下的补偿效应.The study quantumm thermal effect of non-static black hole is generalized to the space-time with coordinate (t,r) as variable. Tortoise coordinate equation which are different from not only static space-time but also the non-static space-time described by advanced-Eddington coordinate have been chosen. On the condition that considering the effect of Hawking evaporation the temperature and the location of horizon of evaporation black hole with global monopoles in De Sitter space-time. Further the results indicate that Hawking radiation temperature can be regarded as a compensate effect under the time-scale transformation.
