早炸 meaning in English

early detonation
premature burst
premature detonation

The conclusion shows that the reason of early burst in shooting tests is not due to the force change of ballistic spring under high rotation speed
该结论说明在一般情况下引信早炸故障不是由于弹道簧在高速旋转下抗力下降引起的。
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。
