摘　　要：为了获得雷管延期药延期精度的影响因素,改变延期药中的硅粉粒度以及延期体的切长后测得单位秒量并进行分析,结果表明:切长较小的延期体单位秒量总趋势上相对较大,可能与延期体的前期燃烧速度未达到相对稳定有关;延期体中硅粉的粒度越小,延期体的单位秒量越低,另外延期体中硅粉的粒度越小,延期体的单位秒量精度越好,其有利于提高雷管的延期精度。In order to obtain influence factor of delay precision for detonator, the silicon particle in delay-compositions and the length of delay element are changed in the experiment. The delay time were obtained by analyzing the data. The results showed that specific delay time of delay element decrease with the increase of the length of delay element, because the combustion velocity of delay element did not reach the relatively stable in initial period. Specific delay time of delay element increase with the increase of the silicon particle size. The delay precision of delay element is better with the increase of the silicon particle size, which is advantageous to the delay precision of the detonator.
