| 摘 要： | 比较了在牛顿力学和广义相对论框架中有效势的特征，对比了广义相对效势和两种伪牛顿有效势（PW有效势力和LC有效势）所对应的最内稳定圆轨道半径和放能效率，结果表明，PW有效势能很好地描述检验粒子在Schwarzschild黑洞赤道面上的轨道特征，LC有效势也能较好地模拟检验粒子在Kerr黑洞赤道面上的轨道特征（顺行粒子向快转黑洞吸积的情况除外）。

| Abstract: | The characters of potential derived from Newtonian mechanics are compared with that derived from general relativistic theory. The orbit radius of innermost stable circular and release efficiency of general relativistic effective potential with those of two types of Pseudo Newtonian effective potential (PW effective potential and LC effective potential) are contrasted. It is shown that orbits characters of test particles located on equatorial plane of schwarzschild black hole can be described well by PW effective potential and LC effective potential can simulate those of Kerr black hole mostly (except for the case of prograde particle accticle accreted by a fast spin black hole). |
