复数：apoapsides  

英汉解释

n.	1. 〔物〕远重心点 2. 远拱点 3. 最远点

英英解释

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.

以太阳为中心的最远点；在天体运行轨道上距离太阳最远的点。

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

这时可以「免费」在近心点产生推力，渐渐将远心点的高度提升。

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

重复在远心点施以推力，会将近心点由同步轨道内提升到同步轨道外。

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

首先在位于同步轨道以外的远心点启动EDT，产生推进力和能源。
