激光多普勒测速仪的出现使紊流速度场的准确测量变成了现实，紊流火焰温度分布和浓度分布等标量的测试研究成了国内外燃烧研究工作者极为感兴趣的课题。阐述作者在德国宇航院燃烧物理化学研究所采用激光自发喇曼散射法（ＬａｓｅｒＳｐｏｎｔａｎｅｏｕｓＲａｍａｎＳｃａｔｔｅｒｉｎｇ）所进行的紊流扩散火焰实验研究工作，其测试结果与采用紊流雷诺应力模型的数值模拟结果十分吻合
The emergence of laser Doppler velocimetry has made the accurate measurement of turbulent velocity field become a reality. The research on the scalar of turbulent flame temperature distribution and concentration distribution has become a subject of great interest to the combustion researchers at home and abroad. The experimental work of turbulent diffusion flame experiment by Laser Spontaneous Raman Scattering (LSSR) was demonstrated at the Institute of Combustion Physics and Chemistry, German Aerospace Academy. The results are in good agreement with the numerical results of the turbulent Reynolds stress model
