heavenly sphere

基本解释

They are unchanging, that's the heavenly sphere.
它们亘古不变，那是神圣的领域。
Beneath the heavenly sphere this solar cycle is mirrored in the lunar cycle of wax and wane and tidal ebb and flood.
在天球里，太阳的活动周期也反映在月亮的盈亏圆缺和相对应的潮起潮落的月运周期。
To reinforce the notion of the heavenly movements being as close to unchanging as possible, it was pointed out that only the motion of a sphere on its axis ends exactly where it begins.
为了巩固天体的运动是趋于没有变化的这一观点，希腊人指出天体围绕轴线旋转一周的终点就是它的起点。
