A variety of devices and means promoting the initiation of detonation were tested, and fully developed repetitive C-J detonation waves were obtained during the experiments. 试验中尝试了各种促进起爆的方法,获得了充分发展的脉冲爆震波。
The position of the initiation point determines the propagation direction of detonating wave in charge, and therefore influences the detonation load and blasting effect. 起爆点位置决定了爆轰波在装药中的传播方向,从而影响爆炸荷载和爆破效果。
In order to achieve a rapid initiation of detonation in a short distance, a flame jet ignition system was applied to the pulse detonation rocket engine ( PDRE). 为了实现快速短距起爆,火焰射流点火系统被尝试应用在脉冲爆震火箭发动机上。
Two Models of Blast Initiation of Detonation in Decane Spray 用爆炸波起爆癸烷云雾的两种模式
In addition, mechanics for SIP is very complex, and the shock initiation course would vary with the small differences of initial or boundary conditions, which could lead to two completely different results: steady-state detonation and extinction. 另外,冲击起爆过程的机制十分复杂,会随初始条件及边界条件的微小变化而产生两种迥然不同的结果,即稳态爆轰和熄爆。

According to stress histories recorded from Lagrangian gauges in a plane shock initiation experiment and calculation result with other reaction rate models, the TANG model can't model process of shock to detonation of PBX-9404 at low pressure. 根据实测压力历史曲线以及用其它反应速率计算得到的压力历史曲线,发现TANG模型在低冲击起爆压力下不能模拟PBX-9404炸药的冲击起爆过程。

In this paper, jet initiation mechanism and criterion of high detonation velocity explosives have been discussed in detail on the basis of investigating and analysing a number of references. 本文通过对国内外现有资料的调研、整理及分析,详细介绍了射流起爆高爆速炸药的过程、起爆机制及临界判据。
To get the condition of critical initiation of shield PBX and composition B by jet, a penetration and detonation experiment is designed. The critical thickness of shield planes are obtained from penetrating and detonating of different thickness of shield PBX and composition B by jet. 为得到聚能射流引爆屏蔽PBX和B炸药的临界条件,采用某制式聚能装药对不同厚度屏蔽板屏蔽的PBX和B炸药进行了侵彻引爆实验,得到屏蔽炸药临界引爆的屏蔽板厚度;
Different ways of initiation produce different shapes of detonation wave, and the jet performances prove to be better when the wave shape better matches the outside shape of the liner. 不同的起爆方式在装药中产生不同的爆轰波形,当爆轰波波形与药型罩外表面越接近时,罩微元的压垮速度越高,导致射流头部速度越高;
