摘　　要：进行了燃料空气炸药装置的静爆试验,获得了地面超压、作用时间及冲量的实测数据,分析得到了各自的拟合公式。研究结果表明,FAE爆炸场可划分为云雾区、边缘区和冲击波作用区,其中云雾区和边缘区是强毁伤区;在云雾区,超压和冲量波动平缓,保持高超压和大冲量特征,正压作用时间在1.18～1.27ms小幅波动;在云雾区外,超压和冲量呈衰减趋势,其中冲击波作用区较边缘区衰减缓慢,正压作用时间呈增长趋势,尤以边缘区增长更为迅速。According to the FAE static blast experiment, the experimental data of three parameters (overpressure, positive pressure time and impulse) were obtained, and the separate fitting formulas were given.Investigation results indicated that the FAE blast field was divided into cloud zone, cloud boundary zone and shock wave zone, the first two were strong damage zones.In the cloud zone,overpressure and impulse fluctuated slowly, and it maintained high overpressure and strong impulse features, and its positive pressure time fluctuated between 1.18 ms and 1.27 ms.Beyond the cloud zone,overpressure and impulse presented decay trend, however the trend was more slow in the shock wave zone than in the boundary zone. Positive pressure time presented growth trend in the latter two zones, however the increase was more rapid in the boundary zone than in the shock wave zone.
