The moment of precession and nutation is a prerequisite to explain these phenomena and one main way of building nutational serial of rigid Earth.

岁差章动力矩是解释这些现象的前提条件，也是建立刚体地球章动序列的最主要方法之一。

This paper is very importance to more studying theory of the inner core Earth's nutation, in view of influence of higher order moment of precession-nutation to the Earth rotation.

本文的理论对进一步研究在高阶岁差章动力矩作用下的内核地球章动是非常有意义的。

And so I know now I can substitute that in there rMg so I get an omega precession now equals rMg times the moment of inertia.

我知道我可以替换,得到ω等于,乘以时间惯量。
