摘　　要：采用高速摄像法研究了硅系延期药压药密度对燃烧稳定性的影响。结果表明:延期药压药密度过小,容易产生跳跃式的无规律的燃烧现象,燃烧反应不稳定;一定范围内,延期药压药密度越高,燃烧速度越慢,燃烧越稳定;延期药压药密度与燃烧速度存在二次曲线关系。该研究对高精度延期雷管的研制具有一定的指导意义。This paper studies the effect of charge density on combustion stability of silicon type delay explosive by the technique of high-speed camera. Results show that the small of charge density of delay explosive, which is prone to cause the jumping and irregular combustion phenomena, leads to the instability of combustion; within a certain range, the higher charge density is, the slower burning rate will be, and the more stable combustion will be; the relationship between charge density and burning rate is quadratic curve. Some directive significances can be provided for the development of high-precision delay detonator.
