本文测量了四种不同爆速的常用工业炸药在地面起爆时产生的压力-时间曲线。结果表明，在距起爆点25和50 m处测量时，炸药的爆炸波形没有显著差异。对峰值超压和正相脉冲数据的分析得出了两个标度距离处材料的TNT当量值。我们的工作表明，TNT当量值的研究材料的变化与缩放的距离，无论是从超压或脉冲。
We report measurement of the pressure-time profiles produced by the initiation at ground level of four common commercial sector explosives with different detonation velocities, The results indicate that there are no significant differences in the blast waveshapes from the explosives when measured at distances of 25 and 50 m from the initiation point. Analysis of both peak overpressure and positive phase impulse data has yielded values for the TNT Equivalence of the materials at two scaled distances. Our work indicates that the TNT Equivalence values of the materials studied vary with scaled distance and on whether they are evaluated from overpressure or impulse.
