我们报告了在预混层流H（2）-空气火焰中沿沿着的温度和大多数组分浓度的空间分辨同时测量。结果是从拉曼和瑞利散射通过使用窄带KrF准分子激光器和光谱和空间分辨检测器系统，该系统由高通量光谱仪和门控，增强，二维CCD相机。这里提供的数据是超过100次激光发射的综合数据。给出了N（2）、O（2）、H（2）O和H（2）的绝对密度分布以及火焰中不同高度的温度分布。所需的校准程序的讨论和必要的光谱背景的总结也包括在本文中。
We report on spatially resolved simultaneous measurements of temperature and majority species concentrations along a line segment in a premixed laminar H(2)-air flame. The results are obtained from Raman and Rayleigh scattering by using a narrow-band KrF excimer laser and a spectrally and spatially resolving detector system that consists of a high-throughput spectrometer and a gated, intensified, two-dimensional CCD camera. The data presented here are integrated over 100 laser shots. Absolute density profiles of N(2), O(2), H(2)O, and H(2), as well as temperature profiles at various heights through the flame, are presented. A discussion of the required calibration procedures and a summary of the necessary spectroscopic background are also included in this paper.
