动态轴对称黑洞的蒸发

把对动态黑洞量子热效应的研究推广到用（ｔ，ｒ）坐标锚述的时空，进一步发展了研究动态黑洞的乌龟坐标方法，给出了动态轴对称黑洞的视界位置和温度以及热谱，这类动态黑洞的视界面是一个随时间变化的椭球面，Ｈａｗｋｉｎｇ温度不仅随时间变化，而且与角度有关。

EVAPORATION OF A NON-STATIONARY, AXIALLY SYMMETRIC BLACK HOLE

The research on the quantum thermal effect of non-stationary black holes is generalized to the space-time described by the coordinates (t, r). The tortoise coordinate approach dealing with non-stationary black holes is further developed. The location of event horizon, the temperature and the thermal spectrum of the non-sta-tionary, axially symmetric black hole are shown. The event horizon surfaces of this sort of non-stationary black holes are ellipsoids. The Hawking temperature depends on not only the time, but also the angles.
