查询词典 equinoxes

equinoxes：二分点

半导体(semiconductors)和金属间的界面以及不同类半导体的界面都存在势垒,不过高度较低. 在设计电子器件时,势垒是重要的. 由于地球旋进运动(precessional motion)的结果,二分点(equinoxes)环绕黄道向西慢速运动. 二分点绕黄道的周期为25800年. 测量压力的装置,

precession of the equinoxes：分点岁差

简言之,这就是"分点岁差"(precession of the equinoxes)的含义. 音乐剧<<秀发>>(Hair)有名的台词"宝瓶座的时代来临了",就是分点岁差的最佳写照. 它提到一个天文事实:在过去2000年间,每一年春分,太阳都是从双鱼座升起,然而,双鱼座的时代如今快要结束了,
