| 摘 要： | 本文详细讨论了在Blandford－Znajek过程中吸积盘中心黑洞的角动量和质量的总变化率与质量吸积率和能量提取率之比的关系，在此基础上讨论了BlandfordZnajek过程对黑洞吸积盘内边缘半径r_(ms)演化的影响，并证明在此过程中中心黑洞的熵总是增大的。

| Abstract: | The relations between the total evolution rate of mass and angular momentum and the ratio of the mass accretion rate to energy extraction rate concerning the central black hole of an accretion disk in the Blandford-Znejek process are investigated in detail in this paper.The effect of the Blandford-Znajek process on the evolution of the inner marginal radius of the black-hole accretion disk is discussed on the basis of the above relations. In addition, it is shown that the entropy of the central black hole always increases in this process. |
