【摘要】研究了二极管激光诱导含能材料点火的化学反应机理,建立了时间分辨光谱测试系统,测量了在激光作用下B/KNO3的光谱发射历程,探测到了二极管激光作用下一些中间产物,而且可以观察到二次点火现象。实验和计算结果表明:B/KNO3在激光作用下的点火机理属于热点火机理。更多还原

【Abstract】 An igniting and testing system are set up in order to deeply understand the reacting mechanism of energetic materials induced by laser diode.Emission spectrum of B/KNO₃ induced by laser diode is measured.There is a twice-ignition phenomenon.Some intermediate products are detected.The results suggest that the laser diode ignition is thermal mechanism.更多还原
