[英][pri'seʃən] [美][prɪ'sɛʃən]
岁差
1.
Astronomer He Chengtian is generally regarded in historical astronomy as having proclaimed that precession of the equinoxes“recedes on degree per hundred years”in“The Memorial to the Throne”.
按天文学史界通行的观点,天文历算家何承天(370~447)在“上元嘉历表”(443)中提出了赤道岁差“百年退一度”。
2.
It shows that obliquity cycle is stronger than precession cycle in the 2.
综合分析结果显示:在整个演化过程中,由于北半球夏季太阳辐射与南半球潜热输出相位关系的不同,导致斜率周期一直强于岁差周期;在987-1552 ka阶段,15 ka、10。
3.
It is an effective way to explain the year of observation of the four mid-season stars recorded in Yao Dian 《尧典》based on the principal of Precession.
利用岁差原理进行推算,是解决《尧典》四仲中星观测年代问题的有效途径。
6) differential epicyclic
差动行星轮
1.
A formula for calculation of resistance moment is established based on analysis of the moving characteristics of the differential epicyclic cutting tool.
通过对差动行星轮钻具切削刀具运动特性的分析，建立了阻力矩的计算公式；理论分析表明：行星轮公转与自转的速比，影响着每个切削刀具的阻力矩的大小与方向；而单个切削刀具阻力矩的相互叠加与抵消决定了整个钻具的阻力矩的大小。
