Even Newtoniangravity works quite well within its domain (eg small velocities).
即使是牛顿引力工程领域内的比较好(如小速度)。

He has also managed to derive Newtoniangravity from the model: however, general relativity has not yet emerged.
他曾成功的从这一模型中获得牛顿引力:但是,广义相对论还未出现。

Post Newtoniangravity correction to the acceleration of gravity in general relativity, produced by the sun and some planets, is calculated and discussed, and is compared with Newtonian tidal force.
