摘    要:对带有电荷、磁荷的任意加速黑洞,得到它的局部视界面方程. 由于这种黑洞是动态和非轴对称的,它的熵很难计算.引进一个新的坐标系,使得其中的00在视界面上正好是零.在此新坐标系下利用膜模型计算了该黑洞的熵. 计算结果表明:和稳态黑洞一样,动态黑洞的熵也是正比于它的视界面积.

关 键 词:黑洞视界  黑洞熵  膜模型

Abstract:The horizon equation of the arbitrarily accelerating black hole with electrical and magnetic charges is obtained. The space time of the black hole is nonstationary and non spherically symmetric and its entropy is dificult to calculate. A new coordinate system is introduced, in which the infinite surface is identical with the event horizon. The entropy of the black hole is computed through the thin film model. The results is that the entropy of the hole is proportional to its area of the event horizon, which is the same conclusion as in the stationary black hole.
Keywords:event horizon  entropy of black hole  thin film model
