Thus an analytic formula with two parameters of high explosive (i. e. detonation velocity and polytropic index) for estimation of the velocity of flying plate is established.

从而给出了用爆速和多方指数等两个炸药示性参量表出的估算飞片运动的良好近似公式。

The one-dimensional problem of the motion of the rigid plate under explosive attack has an analytic solution only when the polytropic index of detonation product equals to three.

刚性飞片在炸药爆炸作用下的一维抛掷问题，仅当爆炸气体多方指数等于三时可以求得解析解；
