相干反斯托克斯喇曼光谱测量技术

摘要

根据燃烧诊断的需要，研究了理论相干反斯托克斯喇曼光谱（CARS）与温度、浓度和压力的关系，在液化石油气/空气预混火焰中进行了氮分子CARS测温实验。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, correlation between theoretical CARS and concentration and correlation between theoretical CARS and pressure. Also, LPG/air flame temperature was measured with N2 CARS.
