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素。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 |

冲击波压力损失与炸药的爆炸压力有关、可以通过计算炸药的密度和爆速来估算。因此、炸药的冲击波压力损失的测定可以通过实验引人一些诸如温度、静态和动态预压及导爆索支线等变量来确定 | The shock pressure loss is related to the explosive's detonation prepressure, which can be estimated by knowing the density and detonation velocity of the explosive. Therefore, the SLF for a test explosive can be experimentally determined by introducing in the test certain additional variables, such as temperature,static and dynamic pre-compression and detonating cord downline |
