我们回顾了后牛顿（PN）展开的相对论修正的二元黑洞系统的运动。利用牛顿形式，我们推导了考虑小速度和弱场的二阶PN修正的轨道方程。从后牛顿近似下的波动方程出发，计算了激光干涉引力天文台（LIGO）能够探测到的引力波（GW）的h+和h×偏振态。
We review the post-Newtonian (PN) expansion for the relativistic correction to the motion of a binary system of black holes. Using the Newtonian formalism, we derive the orbital equations for the 2nd order PN corrections, considering small velocities and weak fields. From a wave equation obtained by the post-Newtonian approximation, we find the h+ and h× polarization of the Gravitational Waves (GW) which could be detected by Laser Interferometer Gravitational Observatory (LIGO).
