一组雷管的平均起爆时间一般稍微偏离标称的起爆时间。这种平均值对公称值的偏移则是第一个影响定时精确的因。在平均值附近的起爆时间分布是第二个因素The mean or average firing time for any group of detonators typically is slightly offset from the nominal firing time. This shift of the mean from the nominal is the first timing accuracy factor. The distribution of the firing times around the mean firing time is the second factor

影响聚能效果的因试验表明,锥孔处爆轰产物向轴线汇聚时,有下列两个因素在起作用: 1. 爆轰产物质点以一定速度沿近似垂直于锥面的方向向轴线汇聚,使能量集中。 2. 爆轰产物的压力本来就很高,汇聚时在轴线处成更高的压力区,高压迫使爆轰产物向周围低压区压膨胀,使能量分散influence factors of cumulative effect
