摘要
通过在传火管点传火特性模拟试验装置上进行的不同装药材料、装填密度和不同的点火能量试验以及获得的多点压力时间曲线、火焰传播速率，分析了底火火焰在传火管装药床中的传输特性，指出了底火火焰与装药材料性能的相互作用关系，特别是因底火作用而导致传火管装药床的挤压程度对点传火性能的重要影响。
In this paper,analysis of the perssure vs time curve and the fire propagation rate,acquired by various experiments of igniter powder,charge density and ignition energe in the simulation device of the fire transfering tube,the flame propagation characteristics of the primer are obtained.The result show that the flame propagation characteristics in the fire transfering tube depend on the flame strength of the primer and the characteristics of the igniter powder.It is important that the intergranular compressive stress of the igniter bed has great role on the flame propagation as the result of the action of the primer.
