进动
简介进动(precession)是自转物体之自转轴又绕着另一轴旋转的现象，又可称作旋进。在天文学上，又称为“岁差现象”。
岁差
岁差(Precession):地球自转以25800年为周期进行摆动，造成天极和天球坐标移动，称为岁差。 日珥(Prominence):从太阳表面 …
旋进
旋进（precession）：高速旋转的物体，其自转轴绕另一个轴转动的现象。一般地说，转动刚体的角动量 但若刚体质量对转轴 …
差数
因 为地球有岁差数(precession)的问题，所以这是按照 10500BC 的天象而定。猎户座对埃及人有重要意 义的，因为他们相信神 …
进动性
进动性(Precession)：在外力矩作用下， 陀螺自转轴转动方向与外力矩作用方向 不一致，而力图使转动矢量以最短路径 向外力 …
岁差运动
1. 岁差运动(precession) : 『进动』是自转物体之自转轴又绕著另一轴旋转的现象，又可称作旋进。在天文学上，称为「岁差现 …
会进动
为何轨道会进动（Precession）？所谓进动（Precession）是指卫星从地球赤道出发循既定轨道绕地一周回到赤道时不经过原点 …
