摘　　要：根据发动机燃烧诊断的需要 ,在指出理论相干反斯托克斯喇曼光谱 ( CARS)与温度和压力的关系后 ,对液化石油气 /空气预混火焰中进行了氮分子 CARS测温实验 ,研究了压力对实验 CARS光谱的影响 ,探索了对湍流场测量十分重要的单脉冲测量技术。结果表明 ,CARS是一种很有前途的发动机燃烧诊断技术。In order to apply Coherent Anti stokes Raman Spectroscopy(CARS)to combustion diagnosis,this paper studied correlation between theoretical CARS and temperature and correlation between theoretical CARS and pressure.Also,LPG/air flame temperature was measured with N 2 CARS.The influence of pressure on experimental CARS was studied.Some work was done to develop the single shot measurement technology that is important to measuring in turbulent field.
