给出了含有整体单极子的黑洞的引力场中试验粒子加速度的表达式,讨论了整体单极子对加速效应的贡献.结果表明,由于整体单极子的存在,产生了斥力效应;当速度趋近于光速时,中性粒子在引力场中受到了斥力作用.这是牛顿力学中所没有的.
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.
