| 摘 要： | 分别研究了用Ｅｄｄｉｎｇｔｏｎ－Ｆｉｎｋｅｌｓｔｅｉｎ时间ｖ和普通时间ｔ描述的二维动态时空中的对称黑洞，得到了局部事件视界、温度和标量场的热谱．用ｔ描述的动态对称黑洞有奇特的结构，它的局部视界个数是对应静态黑洞的２倍，有理由推测最外面的２个局部事件视界之间存在量子能层，因此解析延拓方法不同于稳态黑洞和ｖ描述的动态黑洞．还给出了一个确定广义Ｔｏｒｔｏｉｓｅ坐标变换的普遍适用的新方法

| Abstract: | The symmetric black holes in 2-dimensional non-static space-times described by the Eddington-Finkelstein time v and those by the general time t are studied respectively.The local event horizons,the temperatures and the speora of scalar field are given.The non-static symmetric black hole described by t possesses a surprising structure,the number of whose local horizons is double that of the correspondent static black hole.It is reasonable to infer that there exists a quantum ergosphere between the most exterior two local event horizons.Therefore,the approach of the analytic extension is different from that applied to stationary black holes and non-static or non stationary black holes described by the time v.Besides,a universal new method to determine the generalized tortoise coordinate transformation is given. |
