由高速摄像机拍摄的鞭炮,火药和原子弹爆炸图片,得到了冲击波的半径和时间数据.数据表明,冲击波以匀速传播。
The semi-quantitative radius and elapsed time of blast waves produced by fire- works, gunpowder and nuclear bomb are extracted from the pictures captured by high speed camera. The fitting data means that the blast waves expand in a constant velocity.
