【摘要】 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。更多还原

【Abstract】 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 higher 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.更多还原
