在4060 K ≤ T ≤ 6060 K温度范围内测量了反射激波后CN自由基的热分解。非常低的初始浓度的C2 N2在氩气中高度稀释的冲击加热和N和C原子的浓度进行了监测，在后冲击反应区，通过使用原子共振吸收光谱（ARAS）。根据测得的N和C原子浓度分布的初始斜率，
CN + M（R2）的C + N + M
k2 = 2.5 · 1014 exp（−71000 K/T cm 3 mol−1 s−1
可以直接确定。对于次级反应
CN + CN C2 + C2（R3）
CN + C C2 + N（R4）
CN + N R2 + C（R5）
速率系数由实验结果的最佳计算机拟合获得。本文给出了这些速率系数的推断值。
The thermal decomposition of CN radicals has been measured behind reflected shock waves in the temperature range 4060 K ≤ T ≤ 6060 K. Very low initial concentrations of C2N2 highly diluted in argon were shock heated and the concentrations of N and C atoms were monitored in the post shock reaction zone by using Atomin Resonance Absorption Spectroscopy (ARAS). From the initial slope of the measured N and C atom concentration profiles, a rate coefficient for the reaction
CN + M C + N + M of (R2)
k2 = 2.5 · 1014 exp(−71000 K/T cm3 mol−1 s−1
could be directly determined. For the secondary reactions
CN + CN C2 + C2 (R3)
CN + C C2 + N (R4)
CN + N R2 + C (R5)
rate coefficients were obtained from best computer fits of the experimental results. The inferred values of these rate coefficients are given in this paper.
