1. Science offers no plausible explanation of how it could have slowed to its current rotational rate from that speed. 科学并没有给出合理的解释,说明它是如何从那个速度减速到现在的转速的。
2. Earth's unique and massive satellite, the Moon, plays a crucial role in stabilizing the obliquity of Earth's rotational axis. 地球独特而巨大的卫星——月球,在稳定地球旋转轴的倾角方面发挥了关键作用。
3. Finally, Earth's unique and massive satellite, the Moon, plays a crucial role in stabilizing the obliquity of Earth's rotational axis. 最后,月球作为地球独特而巨大的卫星,在稳定地球旋转轴的倾角方面发挥了关键作用。
4. For an object to be in rotational equilibrium about a certain point, the total torque about this point must be zero. 一个物体若要在某一点处处于转动平衡,在这一点处的总力矩必须为零。
