摘　　要：根据发动机燃烧诊断的需要 ,研究了理论相干反斯托克斯拉曼光谱 ( CARS)与温度、质量分数和压力的关系 ;在液化石油气 /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 。In order to apply Coherent Anti Stokes Raman Spectroscopy(CARS)to combustion diagnosis, this paper studies the correlation between theoretical CARS and temperature, the correlation between theoretical CARS and the concentration 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 has been done to develop the single pulse measurement technology that is important to measuring in turbulent field.

关 键 词：燃烧诊断/CARS 单脉冲测量
