– 地平座标有时也用在其它方面(如航海) Horizon Coordinate (地平座标系) Earth Zenith N E S W Horizon Coordinate ? Two angles – Altitude, a – Azimuths, A ? X: location of star ? B: projec...
Using coordinate transformation, we study the event horizon of accelerating non-stationary black holes, the equation of event horizon surface is calculated out.
采用坐标变换的方法，研究几种加速运动动态黑洞的事件视界，得到了黑洞的视界面方程。

It is pointed out that a coordinate or essential singularity near an event horizon will strongly influence the temperature of the horizon. It is a universal effect in 2-dimensional Riemann Space-time.
