n.軌道；彈道；軌跡

My career seemed to be on a downward trajectory. 我的事業(yè)似乎在走下坡路。

From then on it must coast in a trajectory, or flight path, to its target. 從那時(shí)起，它就得沿著彈道，即沿著飛行航線滑向其目標(biāo)。

It is not difficult to sketch the subsequent trajectory. 很容易描繪出它們后來(lái)的軌跡。

This career trajectory began with a chance conversation with a friend's father. 這種職業(yè)軌跡開始于和朋友父親一次偶然的交談。
