摘要
相对论天体物理中,由于黑洞附近时空弯曲相当严重,我们可以得到一些在平直时空中难以想象的有趣效应。在克尔旋转黑洞的时空背景中,磁场可以转变为电场,在此基础上,我们将讨论电荷的吸积以及克尔黑洞转变为克尔-纽曼黑洞等问题。
in relativistic astrophysics, owing to the serious curvature of space-time in the vicinity of black hole, we can have some interesting effects which are unimaginable in the flat space-time. In the space-time background of Kerr rotating black hole, the magnetic field can be transformed into electric field. The charge accretion and the transforming of Kerr black hole into Kerr-Newmann black hole are discussed.
