摘　　要：利用新乌龟坐标计算了任意直线加速带电黑洞的熵,简化了截断因子,并得到了黑洞熵与黑洞视界面积成正比的结论.而且截断因子与稳态黑洞的相同,都为90β.Using the new tortoise coordinate transformation, we calculate the entropy of a rectilinearly, non-uniformly accelerating and charged black hole, simplifying the cutoff relation, and get the conclusion that the entropy is proportional to the area of its event horizon. It is emphasized that the cutoff is same as those in static cases, 90β.

关 键 词：任意直线加速带电黑洞 截断因子 黑洞温度
