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
