摘　　要：用平面激光诱导荧光 (PLIF)技术测量了烧煤油的酒精喷灯单脉冲激光诱导荧光 ,由平面荧光图可清晰地看到氢氧基与C2、C3 在火焰中的位置 ,同时 ,也看到了煤油火焰由发生、发展到熄灭过程中火焰结构的变化 ;PLIF技术是研究火焰结构的有力工具。The fluorescence images of flame from alcohol blowtorch burning kerosene were obtained by planar laser induced fluorescence(PLIF)technique with single laser pulse.The positions of hydroxy radial,C 2 and C 3 in the flame can be obviously displayed from the images,besides,the full process of change for the flame structure from ignition to extinction can be observed.PLIF technique provides a powerful tool for investigating flame structure.
