| 摘 要： | 采用多项式函数代替乌龟坐标的方法,给出静态球对称时空中黑洞事件视界和宇宙视界区域内标量场方程的解,并对事件视界附近势垒的性质进行了讨论。发现对带电量不同的时空,标量场辐射的形式亦有所不同;势垒随宇宙学常数的减小而变窄、变高。

| Abstract: | The solutions of scalar field equations in the region between the black hole's event horizon and the cosmological horizon in static and spherically symmetrical space-time are given in this paper.The method of replacing the tortoise coordinate with a polynomial function,and the properties of the potential near the event horizons are also discussed.It is found that the radiations different when the charge of the black hole varies,and that the potential is narrower and higher with a less cosmological constant. |
