标题： Gravitational Acceleration of Spinning Bodies From Lunar Laser Ranging Measurements

摘要： 太阳的相对论性引力梯度加速度作用于地球和月球，取决于后两者运动，作用于系统内部角动量。这种自转-轨道力（在确定天体物理源的引力波信号模板中起一定作用）略微加速整个地月系统，但更稳健地以5厘米的会合振荡范围贡献扰动该系统的内部动力学，目前通过三十多年来的月球激光测距已测量到4毫米精度。 显示英文摘要

摘要： The Sun's relativistic gravitational gradient accelerations of Earth and Moon, dependent on the motions of the latter bodies, act upon the system's internal angular momentum. This spin-orbit force (which plays a part in determining the gravity wave signal templates for astrophysical sources) slightly accelerates the Earth-Moon system as a whole, but it more robustly perturbs that system's internal dynamics with a 5 cm, synodically oscillating range contribution which is presently measured to 4 mm precision by more than three decades of lunar laser ranging.
