| 摘 要： | 建立了一套以光纤采集信号的激光点火和温度测量系统,测量了激光作用下B/KNO3点火药的时间分辨光谱。用多光谱测温原理计算了激光作用下点火区瞬时温度,温度变化过程表明在点火过程中存在二次点火现象。

| Abstract: | a laser diode igniting and temperature measuring system is set up,the time-resolved spectrum of B/KNO 3 composition induced by laser diode is measured with this system,the signal is collected by fiber.Based on the multi-wavelength pyrometry,The transient temperature in the ignition zone is calculated.The temperature in the process suggests there is a twice-iugnition phenomenon. |
