periapsis

基本解釋

Periapsis in Earth orbit,the point in its orbit where a satellite is nearest to the Earth.
以地球爲(wèi)中心的最近點(diǎn)，人造衛(wèi)星軌道上離地球中心最近的點(diǎn)。
The angular distance of a point in an orbit past the point of periapsis measured in degrees.
穿過用角度來測(cè)量的進(jìn)拱點(diǎn)的一個(gè)軌道裡的某點(diǎn)的角距離。
The repeated thrust applications at apoapsis would raise periapsis from inside to outside the stationary orbit.
重複在遠(yuǎn)心點(diǎn)施以推力，會(huì)將近心點(diǎn)由同步軌道內(nèi)提陞到同步軌道外。
As the spacecraft went around and around Jupiter, mission controllers would turn on the tether near periapsis to produce drag( and usable power) and turn it off elsewhere.
隨著太空船一遍遍地繞行木星，任務(wù)控制者將在近心點(diǎn)附近啓動(dòng)纜索以産生拖曳力（可用能量）竝在其他地方關(guān)閉它。
