The preferred orientations in the development of non-primary detonator should possess high-safety,non-polution and low-cost.
文中对无起爆药雷管所存在的问题和发展方向提出看法，无起爆药雷管的发展应向高安全、无污染、低成本的方向努力。
The difference of the delay time of non-primary detonator was compared by using PETN and RDX as the excitation powder,and the data were analyzed based on hot spot initiation theory.
为了探讨激发药对无起爆药雷管延期时间的影响,通过对比PETN和RDX分别作为激发药引起无起爆药雷管延期时间的差异,根据热点起爆理论对数据进行分析。
