航空航天术语:航迹/弹道

什么是航迹/弹道?物体在空间移动时,飞过的路径即为航迹,对于弹道导弹,也称为弹道。弹道取决于初速度,而后受到惯性和空气阻力的影响。

What is the trajectory?A trajectory is the path an object follows as it moves through space,while a ballistic trajectory is a path that depends on an initial velocity but then is influenced only by gravity and air resistance.
