dispersion ring
弥散环 -恒星运动
2.
dispersion orbit
弥散轨道 -恒星运动
3.
But the earth is in motion relative to the sun, the sun is in motion relative to some other star, and so on.
但地球相对于太阳运动，太阳相对于某些其他恒星运动，等等。
4.
Based on its movement it could have been a shooting star rather than a fixed star.
基于它的运动，它应该是一颗流星，而不是恒星。
5.
(of divisions of time) determined by daily motion of the stars.
（指对时间的划分）根据恒星的日常运动来确定。
6.
Faster ones slow down and slower ones speed up, so they bring themselves into sync.
运行较快的恒星会减慢下来，而较慢的则加速前进，让自己与其他的恒星同步运动。
7.
This nucleus has captured the slow-moving neutrons; The star captured a comet.
这核子已经俘获慢运动的中子；这颗恒星俘获了一颗慧星。
8.
In chap. 19 we saw that red shifts in stellar spectra result from motions away from the earth.
在第十九章我们已了解到，恒星光谱中的红移是恒星背离地球的运动造成的。
9.
The analysis of starlight with the spectrograph has provided information on the distances, temperatures, sizes, and notions of the stars.
用摄谱仪分析恒星的光谱，可提供恒星的距离、温度、大小以及运动等方面的材料。
10.
In short, stellar orbits can move in unison even if the stars themselves do not.
总之，恒星自身的运动或有不同，它们的轨道却可以一致运行。
11.
The parallactic refraction between the stars and the satellite is small and well determinate, except for the irregular stellar movements known as erratics.
除了通称为游动的不规律星体运动之外，恒星和卫星之间的视差折光差微小，而且是容易测定的。
12.
In a generator, the moving parts are spinning coils of wire; in a planet or star, the motion occurs within an electrically conducting fluid.
在一般的发电机里，运动的部份是旋转的线圈；而在行星或恒星里，运动的则是导电的流体。
13.
Their mutual gravity binds stars into galaxies, every one a complex swarm of moving stars.
它们相互的引力把它们约束成星系，每一个（星系）都是一个复杂的运动恒星集团。
14.
The length of the year, in fact, is determined from this apparent motion of the sun among the stars.
事实上，一年的长短就是根据太阳在恒星中的这种视运动而确定的。
15.
Motion of a star across the line of si ght causes no change in its spectrum.
恒星横越视线方向的运动，在它的光谱中不会引 起什么变化。
16.
Even then he cannot decide whether he or the stars are moving.
即使这样，他仍然无法判断究竟是他还是恒星在运动。
17.
Classification of stars/galaxies based on AutoClass
基于自动聚类算法(AutoClass)的恒星/星系分类
18.
If a star has a companion, it will seem to wobble as it moves across the sky.
如果一颗恒星有一颗伴星，那么当它横越天空运动时，它似乎是摇来摆去。
