摘要: 介绍地球章动的特点,从理论上分析地球章动的主要原因,计算章动常数并给出了地球章动示意图的画法.所计算的章动常数与观测值相差仅2/10 000.

关键词: 地球章动, 岁差, 章动椭圆, 章动常数, 引潮力

Abstract: The main reasons of the earth nutation are analysed theoretically and the nutation constant is calculated.The relative difference between the theoretical calculation value and the observed one is about 2/10 000.

Key words: earth nutation, precession, nutation ellipse, nutation constant, tide force
