Definition

A direction vector u in the xy-plane of the linearized dynamics near a collinear libration point. A velocity increment along this direction excites the exponentially growing unstable component A1, causing the spacecraft to escape from the libration point orbit.

Application Value

在逃逸方向的设计与分析中，可用于优化转移方案，减少燃料消耗 用于分析航天器在复杂引力场中的运动特性 描述系统状态随时间的变化规律，是轨道预报的基础。
