摘要
在乌龟坐标下,如果令动态时空的二维线元在视界附近呈现共形于Minkowski时空的明显形式,就可得到动态视界的位置和温度。
If we demand that the two-dimensional line element of a non- static space-time is explicitly conformal to the two-dimensional Minkowski space-time near an event horizon in the tortoise coordinate both the Haw- king temperature and the location of the horizon will be shown automati- cally.
