詞形變化

復數：apoapsides  

英漢解釋

n.	1. 〔物〕遠重心點 2. 遠拱點 3. 最遠點

英英解釋

n.	1. the point in an orbit that is farthest from the center of gravitational attraction

例句

apoapsis in solar orbit; the point in the orbit of a planet or comet that is at the greatest distance from the sun.

以太陽為中心的最遠點；在天體運行軌道上距離太陽最遠的點。

Now thrust could be generated (for "free" again) at periapsis, progressively increasing the altitude of apoapsis .

這時可以「免費」在近心點產生推力，漸漸將遠心點的高度提升。

The repeated thrust applications at apoapsis would raise periapsis from inside to outside the stationary orbit.

重復在遠心點施以推力，會將近心點由同步軌道內提升到同步軌道外。

They would first switch on the EDT at apoapsis , which lies outside the stationary orbit, to produce thrust and power.

首先在位于同步軌道以外的遠心點啟動EDT，產生推進力和能源。
