apoapsis s 远重心点[1]
Apoapsis in earth orbit; the point in its orbit where a satellite is at the greatest distance from the earth.
以地球为中心的最远点；人造卫星轨道上离地球中心最远的点。
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。[1]
