摘　　要：应用遥感FTIR对固体推进剂燃烧火焰的温度进行了研究。遥感FTIR光谱仪在光谱分辨率为 4cm-1时 ,连续收集燃烧火焰的发射光谱。分别利用分子基带转振光谱测温法 ,以及分子发射光谱最大强度谱线测温法 ,对燃烧温度进行了遥感实时测定。文中列出了两种方法测得的各时刻的火焰温度。结果表明 ,两种方法在测量快速、剧烈燃烧的火焰温度时 ,都是很可靠的方法 ,当火焰的燃烧比较稳定时 ,分子发射光谱最大强度谱线测温法更为简便。The combustion temperature of solid propellant was measured in this paper. Emission spectra of the combustion flame were collected with remote sensing FTIR at the resolution of 4 cm(-1). The combustion temperatures with the burning time were calculated from the maximum spectral line intensity and the molecular rotation-vibration spectra of HF molecule, respectively. Combustion temperatures at each time were all 1788.8 K from the maximum spectral line intensity method. For comparison, the temperatures calculated from the molecular rotation-vibration spectra were 1859.7, 1848.3, 1804.0 and 1782.7 K, respectively. Results show that the two methods are all dependable in measuring combustion temperature of solid propellant. But the maximum spectral line intensity method is more convenient and rapid than the other when the combustion is relatively stable.
