摘　　要：为了解固态燃料空气炸药的扫雷应用特性，通过野外0．5kg一次引爆型固态FAE的近地面爆炸实验，获得爆炸场不同位置处的峰值超压值，由爆炸相似率推出了固态FAE在各测点的TNT当量比、比冲量及正压区作用时间，并通过与等质量TNT对比，获知固态FAE近地面爆炸场的峰值超压是TNT的1．3～2．3倍，比冲量是TNT的1．31～2．51倍，正压区作用时间是TNT的1．07～1．21倍。结果表明，固态FAE近地面爆炸场威力参数明显大于等质量的TNT，中远场优势尤为明显，固态FAE的扫雷效率约为等质量TNT的1．90～4．49倍，且其正压区作用时间长的特点有益于耐爆地雷的清扫。To study solid FAE＇s characteristics in mine sweeping, the contrast experiments between 0.5 kg solid FAE and TNT were carried out near the ground in the field, and the peak overpressure in different positions was obtained. According to the similitude law of explosive, the equivalent proportion of TNT, impulse and duration of positive-pressure area were reasoned out. It could be found that the peak overpressure of solid FAE was 1.3-2.3 times as high as that of TNT, that the impulse of solid FAE was 1.31- 2.51 times as strong as that of TNT, and that the duration of positive-pressure area of solid FAE was 1.07 - 1.26 times as long as that of TNT. The results indicate that the value of peak overpressure of solid FAE, impulse and duration of positive-pressure area are greater than those of TNT with the equal mass, that the preponderance of solid FAE is obvious in the middle and far field, and that the maximum mine sweeping efficiency is 1.90-4.49 times higher than that of TNT with the equal mass. The solid FAE＇s duration of working time in positive pressure area is propitious for sweeping mines which can endure explosion.
