| 摘 要： | 分别研究了碳黑、石墨、KCl和石蜡四种掺杂物对Zr/KClO4点火药及碳黑对B／KNO3点火药的激光点火感度和延迟时间的影响。实验结果表明，四种掺杂物均能降低药剂的激光点火延迟时间（其中碳黑的效果最强，石墨的效果最弱），但只有碳黑能够降低药剂的激光点火感度。

| Abstract: | This paper studied the effects of carbon black, graphite, KCl and olefin on the diode laser ignition characteristics of Zr/KClO 4 and carbon black on that of B/KNO 3, so as to provide experimental basis for changing characteristic of ignition composition ignited with diode laser. The experiments show that only carbon black can increase the laser sensitivity of the two ignition composition. The four dopants can decrease the delay times of the ignition composition, and the carbon black is the best while the graphite is the worst. |
