| 摘 要： | 利用多通道光学分析仪测量激波波后不同时刻高温氮气的辐射光谱发现，辐射随时间发生强烈的变化。在非平衡态和平衡态，光谱的各条谱线强度有明显的差别。光谱的结构特征也依赖于激波的速度。

| Abstract: | The emission spectrum of nitrogen gas behind normal shock wave at different moments is measured with an optical multichannel analyser . The experimental results reveals that the spectrum gradually evolves from none quilibrium state to equilibrium state after the shock wave passing. Meanwhile, t he spectrum is also related to the shock wave velocity. |

| Keywords: | shock wave shock tube shock wave velocity nonequilibrium radiation instantaneous spectrum nitrogen molecule |
