摘　　要：采用一种新的Tortoise坐标变换,在讨论任意加速带电动态黑洞的热性质时,不但保证了熵与面积成正比的结论,而且得到了和静态一样简单的截断因子。这种坐标变换在讨论黑洞的Hawking辐射、熵及非热辐射时,表现出了前后的一致性与和谐性。When we discuss the thermal properties of arbitrarily accelerating non-stationary black hole with electric charge,using a new tortoise coordinate transformation allows us to obtain the conclusion that the entropy of the black hole is proportional to its surface area,and the cut-off relation as simple as static case.Using the new Tortoise coordinate transformation in discussing the black hole’s Hawking radiation, entropy and non-thermal radiation,the conclusion is coincident and harmonious.
