precession of the earth

A slow westward shift of the equinoxes along the plane of the ecliptic caused by precession of the Earth's axis of rotation.

随着地轴的转动昼夜平分线沿黄道平面向西缓慢移动的过程。

The so-called precession is caused by the inequality of the moments of inertia of the earth.

所谓日月岁差,是由于地球转动惯量的不相等造成的.

The so-called lunisolar precession is caused by the inequality of the moments of inertia of the earth.

所谓日月岁差，是由于地球转动惯量的不相等造成的。

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。

The reason of physical mechanism of residual precession for planet and ratio equation of precessional angle of Earth and Mercury are presented, finally the calculating result shows the existence of DM.

文中给出了行星剩余进动的原因，水星和地球进动角比值的计算公式，而且计算结果在某种程度上说明了DM存在的真实性。
