摘　　要：本文实验测试了硼系延期药和硅系延期药燃烧传播过程,根据实验结果分析了延期药燃烧传播机理,认为延期药在铅管内的燃烧是脉动燃烧,是影响雷管延期精度的主要因素,其次点火药头的影响作用也十分明显。在不影响传火可靠性的前提下,减小延期药芯直径,提高装药密度,可使燃烧得以稳定传播。This paper tests the Combustion Propagation process of boracic and siliciferous delay composition with experiment According to the experiment results, the author analyses the combustion propagation mechanism of detonator delay composition and believes that the combustion in the lead tube is impulsive combustion, which is the key factor of influencing the delay precision of the detonator; secondarily, the effect of the igniting power terminal is also very obvious. On the premise of not affecting the reliability of the combustion propagation, shortening the cliameter of the core medicine and increasing the charge density can make the combustion stably propagate.
