凝聚相炸药爆炸火光现象的初步研究

为弄清凝聚相炸药爆炸火光现象的形成机制及影响爆炸发光现象的相关因素，对凝聚相炸药爆炸过程中存在发光现象的各阶段发光机制进行了理论分析，用文献试验结果分析了影响爆炸发光强度的因素。采用高速摄像的试验手段研究了16种凝聚相炸药的爆炸火光现象。结果表明，凝聚相炸药的爆炸发光过程由爆炸和后燃两阶段组成。凝聚相炸药的爆炸发光强度与炸药的爆压、爆温、爆速和氧平衡均有关系。而炸药的氧平衡和质量则影响爆炸火光现象持续的时间。

Primary Study on Phenomena of Firelight Radiating from Explosion of Condensed Explosives

In order to understand the mechanism and factors of firelight radiating from explosion of condensed explosive,theoretical analyses on mechanism of radiation in each phase of explosion of condesed explosive were proceeded.The factors affecting the intensity of radiation based on analyses on experimental results in literature were studied.The phenomenon of firelight from explosion of sixteen kinds of condensed explosives were investigated with high speed photography.The results show that the process of radiation of firelight from explosion consists of two phases:detonation and afterburning.The detonation pressure,detonation temperature,detonation velocity and oxygen balance of condensed explosive have effect on the maximal intensity of radiation during explosion.The duration of firelight from explosion of condensed explosives is influenced by the oxygen balance and the mass of condensed explosive.
