摘要
依据热爆炸理论，分析了火工品的延期机理，给出了延期火工品作用过程的燃速──时间、能量──时间物理模型。剖析了影响延期精度的诸因素，并推导出影响精度诸因素的时间值之和△t（不稳态燃烧时间）与稳态燃烧时间t之比α、△t与延期技术指标中间值T之比分别存在边界值。
This paper makes an analysis on the delay mechanism of initia-tors, and gives out two physical models on combustion process. It can be consid-ered that a and 5 exist boundary values,where a is the ratio of the total of time values influencing delay precision (unsteady combustion time )△t and the steady combustion time t ,β is the ratio of △t and the mean value of delay index T.
