摘　　要：得到了双基推进剂燃烧火焰CARS实验谱图及相应的温度拟合值。实测结果表明,燃烧火焰平衡区的CARS实验拟合温度数值与相应的热力学计算温度值基本吻合,连续采集的CARS谱显现的温度梯度说明CARS技术可以应用于推进剂燃烧火焰温度的实时诊断。The combustion flame CARS spectra of the doublebase propellant and its flame temperature values have been obtained. The results show that the temperature measured by CARS spectroscopy is in agreement with values calculated by thermodynamics. The temperature change observed by continuously collecting the CARS spectra indicates that CARS technology can be used for realtime diagnostics of the flame temperature during the propellant combustion.
