Zr-O_2闪光灯辐射特性研究

Emission Spectrum Characteristics of Zr-O_2 Flashlamp

研究了Zr与O2的燃烧特性,测试了Zr-O2闪光灯的发射光谱。实验结果表明:点火电压越高(22V),氧气量越多(0.7MPa),锆条越细(0.3～0.5mm),发火率越高。Zr-O2闪光灯的辐射光谱的分布范围为500～900nm,其中在700～900nm范围的近红外区内有较强的辐射峰。Zr-O2闪光灯的发射光谱特性与锆氧反应速度、反应程度及充氧气的压力等因素无关。

Combustion characteristic of Zr-O2 was studied. Emission spectrum of Zr-O2 flashlamp was also tested. Results show that the higher the ignition voltage （22 V） is, the more the oxygen （ 0.7 MPa） is and the smaller Zr strip （0.3 - 0.5 mm） is, the high- er fire ratio is. The spectrum of Zr-O2 pyrotechnics is distributed from 500 - 900 nm, and it has stronger emission strength in near infrared region of 700 - 900 nm. The spectrum characteristics are almost the same in different ratios of fuel/oxygen.
