石墨掺杂对B/KNO_3点火药的激光点火特性的影响

The Laser Ignition Characteristics Influenced by Graphite Doping into B/KNO_3

用光声检测的实验方法研究石墨掺杂对B／KNO3点火药的激光点火性能的影响。根据对光声谱的分析，指出了石墨掺入B／KNO3会略降低B／KNO3的激光吸收能力并且掺入量增加时，药剂的光吸收能力会有所改善。石墨掺杂会增长B／KNO3的激光点火延迟期，这一规律与石墨掺杂对B／KNO3的吸光性能的影响规律一致。

Research on the effect of laser igniting characteristics caused by doping graphite into B/KNO3 with photoacoustic detection method. Analysed the photoacoustic spectra,we found that the ability of absorption of light of B/KNO3 drops a little when graphite is mixed into the composite, and the ability of the doped composite increases slowly with increasing quantity of doping graphite. Doping graphite can make the delay period of ignition of laser lengthen,in which the law is accordance with the effect of doping graphite into B/KNO3on the ability of absorption of light.
