动态黑洞视界面附近熵密度的讨论

Discussion on Entropy Density Near the Event Horizon of the Non-Stationary Black Holes

利用带有电荷与磁荷的直线加速动态黑洞的熵密度 ,得到了任一时刻黑洞视界面附近沿某一方位角的熵密度总是正比于该处视界温度的三次方的结论。发现直线加速动态黑洞视界面附近的熵密度不仅与时间有关 。

Using the entropy density of the rectilinearly accelerating non-stationary black hole with electric charges and magnetic charges, a conclusion that the entropy density near the event horizon of non-stationary blank hole in a direction is always proportional to cubic power of temperature of event horizon on this direction is obtained. It is found that at anytime the entropy density near the event horizon of the straightly accelerating non-stationary black hole depends not only on the time, but also on the polar angle.
