In the wave trough of the pressure curve, the pressure may be then if the rocket is accelerating or if it has assembling defects, the early explosion of the grenade on the ballistic may be caused.

• 该模型的微分方程计算结果表明微小弹簧在弹道上的振动过程会使导电杆的受压产生周期性变化，尤其是在一些波谷处，导电杆几乎不受压力，此时如果有火箭加速和其它装配缺陷等因素的影响，就会引起弹丸在弹道上的早炸。
