用光学多道分析仪（OMA光学系统）测量了氢氧燃烧驱动激波管中典型状态下正激波后高温空气不同时刻的瞬态光谱。光谱结果显示高温空气的光谱中有很强的OHA2∑＋─X2∏光谱。通过采用线线合成光谱的方法得到激波后不同时刻高温空气中OH分子的转动温度。
The transient spectra of high temperature air at normal shock wave under typical conditions in oxyhydrogen combustion driven shock wave tubes were measured with an optical multi-channel analyzer (OMA optical system). Spectral results show a strong OHA2Σ + -X2Π spectrum in the high-temperature air spectrum. The temperature of OH molecule in high temperature air at different time after the shock wave was obtained by using the method of line synthesis spectroscopy.
