在谐波规范中给出了任意慢速运动中一个点状物体引力场近区光轨迹的后-后牛顿近似的解析解。给出了总光偏转和延时的表达式。提出的解决方案是向高精度天体测量迈出的又一步，目标是达到纳角秒级的精度。
An analytical solution for the light trajectory in the near-zone of the gravitational field of one pointlike body in arbitrary slow-motion in the post-post-Newtonian approximation is presented in harmonic gauge. Expressions for total light deflection and time delay are given. The presented solution is a further step toward high-precision astrometry aiming at nano-arcsecond level of accuracy.
