The dynamics of the Earth-Moon system is quite different from the Sun-Earth system especially after a long duration for the gravitational attraction of the Sun.

由于在地-月系统中太阳的引力不可忽略，特别是在长时间作用以后，其动力学行为与摄动力较小的日-地系统有明显的不同。

And we are acutely aware of the dynamics of the Earth wobble, which can switch into and out of an opposition lean quickly as well as go back and forth in a daily polar wobble.

而且我们清楚地了解地球抖动的动力学，不仅会在每天的极性抖动中来来回回，还会转变成快速地向另外一个方向倾斜。
