介绍了用BOXCARS技术测量CH4/air火焰的温度.给出了甲烷气体不同流量下和火焰不同高度处的温度测量结果,分析了温度随甲烷气体流量变化和火焰高度变化的变化趋势,根据实际的实验参数计算了相应的空间分辨率.实验结果表明:利用BOXCARS技术可进行高精度、高空间分辨的温度测量.

CARS spectra have been recorded and evaluated for temperature determination in CH₄/air flame. Temperature on the flame axis at different height above the burner surface has been measured; It has also been measured with different gas flow rates, and the spatially resolution have been calculated with actual experimental parameter. These results indicate that temperature at the combustion field can be measured with high precision and high spatially resolution by BOXCARS.
