以纵向扰动运动为例，分析了滑翔增程弹的稳定性和操纵性。

Take longitudinal disturbed motion for example, the stability and the controllability of the gliding extended range projectile are investigated.

形象地表现线性小扰动运动方程的纵向和横航向典型运动模态，一直缺乏一种理想的方式。

There is no ideal way so far to represent the longitudinal and lateral motion mode of the small linear disturbance motion equation.

但是，如果扰动影响的地区很大，象强烈地震所能做到的，那末所产生的地震海浪运动好象沿直线产生而不是在一点产生。

But if the disturbance affects a large area, as a great earthquake can, the resulting seismic sea waves nay behave as if they had been generated along a line rather than at a point.
