摘要
介绍了激光感生预分离荧光法（ＬＩＰＦ）的原理及一维与二维测量实验装置。利用可调谐ＫｒＦ准分子激光器，在甲烷一空气火焰中测得了燃烧中间产物ＯＨ的系列荧光谱线及ＯＨ分子的二维荧光图象，对它的话线结构进行了分析，并给出了燃烧火焰的一维温度值，测量的相对误差小于３％。二维荧光图象也定性表明燃烧火焰的ＯＨ分子密度分布和二维温度场等信息。
The principles and the experiment for temperature and OH concentration fields measurement by LIPF is mentioned in this paper. With a tunable KrF excimer laser, the fluorescence of OH was gotin a methane-air flame at the pressure of atmosphere and the structures of the spectrum were analyzed. Theinstantaneous temperature in the flame was also given out by LIPF, the relative error is less than 3%. Thefluorescence images of OH shows the direct images of densities and the tempetature fields in quality.
