[An Analysis of Combustion Emission Spectrum and Combustion Products of KClO4/Zr in the Quartz Tubes].

Aiming at understanding the light radiation properties of KClO4/Zr combusting under different conditions, emission spectrum and combustion products for KClO4/Zr combusting in open air and closed quartz tubes were studied respectively. Energy distribution of the light radiation signal and the emission intensity evolution with time were measured with fiber optic spectrometer, and photo-diode and oscilloscope. Spectral efficiency within (590±10), (750±10) and (808±10) nm were analyzed respectively according to the obtained flame emission spectrum.
