查询词典 orbit

For example, the eccentricity changes over time cycles of about 100,000 and 400,000 years, with the value ranging from less than 0.01 up to 0.05.[15][16] This is equivalent to a change of the semiminor axis of the planet's orbit from 99.95% of the semimajor axis to 99.88%, respectively.

例如，离心率大约在小于0.01至0.05之间变动，变动周期大约是10万年至40万年，这相当于行星运行轨道的短半轴相对于长半轴的比例在99.55%与99.88%之间发生变动。

This paper can infer time of GPS satellite clock that there is a periodic variation of 12 sidereal hour, and GPS satellite orbit period is just 12 sidereal hour, no doubt, it be designed for to check up time.

本理论可以推导出GPS卫星钟的快慢，有12恒星时的周期变化，而GPS卫星轨道周期正好为12恒星时，极可能是为了方便校对时间而设计的。

Jupiter has a sidereal period (its movement with respect to the "fixed" stars) of 11 years, 314 days, and 839 minutes, so in nearly 12 years it is back into conjunction with those stars from which it began its orbit.

木星有一个恒星周期（它的移动与"固定的"星星相关），是11年零314天839分，因此从它的轨道开始，差不多12年的时间，回到了与那些星星关联的位置上。

In order to make motion planning fitting practice,many characteristic of CNC trajectory motion were discussed,such as the geometric,the motion and the time,the relation between orbit function and motional parameter was set up,the differential simultaneous equation about the trajectory motion was derived.
