为验证CO2中流动速度5~7 km/s时，流场中CO离解导致化学反应产物发生变化的推论，在中国空气动力研究与发展中心超高速空气动力研究所的弹道靶设备上开展了CO2中自由飞圆球流场光谱的测量试验。测量数据表明，流动速度约5~7 km/s时，CO2流场中观测到了显著的C2 Swan带特征辐射谱。组分C2生成是组分CO离解的结果之一，验证了该速度范围内组分CO发生离解的推论。根据试验状态开展热化学非平衡流场与辐射光谱数值计算，也得到了组分C2显著生成的结果，再现的流场辐射光谱与试验测量数据偏差约在1个数量级以内，进一步验证了组分CO发生离解推论的合理性。

To validate the deduction that the chemical reaction products change due to the dissociation of CO in flowfield with flow velocity from 5 km/s to 7 km/s in CO2， flowfield spectrum over free-flight spheres in CO2 has been measured in the ballistic range facility of Hypervelocity Aerodynamics Institute， China Aerodynamics Research and Development Center. It is revealed from the test data that the obvious C2 Swan band characteristic spectrum has been observed in CO2 flowfield with flow velocity ranging from about 5 km/s to 7 km/s. The produce of specie C2 is one of the results of the dissociation of specie CO， which validate the deduction of the dissociation of specie CO within the corresponding velocity range. Theromchemical non-equilibrium flowfield and radiation spectrum have been numerical calculated based on the test conditions， which also come to the results that specie C2 has significantly generated. The difference between the reproduced flowfield spectrum and test data is less than approximately one order of magnitude， which further validate the reasonability of the deduction of the dissociation of specie CO.
