【摘要】 运用广义相对论的后牛顿效应,得到洛希(Roche)极限和引力作用范围的近似改正表示式,表明洛希极限不仅与牛顿引潮力及惯性离心力有关,而且受重力后牛顿近似改正的影响。并且估计、讨论了太阳系天体的某些具体情况。更多还原

【Abstract】 Using postNewtonian effect of gravity to general relativity,the appoximate expressions of corrections for the Roche limit and sphere of graviational action are obtained.It is represented that the Roche limit not only depends on Newtonian tidal forces and inertial centrifugal forces,but also may be affected by postNewtonian correction of gravity.Also,Some situations of celestial bodies in solar system were estimated and disucssed.更多还原
