Acceleration effect in the gravitational field of black hole involving a global monopole
整体单极子黑洞引力场中的加速效应

In this paper,we provide the analytical expression of acceleration of neutral experimental particle in the gravitational field of black hole involving a global monopole and discuss the contribution of global monopole to acceleration effect.The results indicate that the repulsion effect takes place due to the global monopole,and when v→c,neutral particle in the gravitational field is subjected to a repulsive force,which does not exist in Newtonian mechanics.
