| 摘 要： | 利用平面激光诱导荧光(PLIF)技术，通过选择适合的OH自由基激励线，定量测量了甲烷-空气燃烧火焰的二维温度场分布。给出炉面中心上方火焰温度随离炉面高度的变化和距炉面12 mm高处沿炉面水平方向变化的实验测量结果并进行了讨论与分析。与利用相干反斯托克斯喇曼散射（CARS）技术进行测温的实验结果相比，该测量的相对不确定度优于5％。

| Abstract: | In this paper, the principle and experimental setup of PLIF is discussed. Through the proper choice of OH excited lines and improving the beam quality of the laser by spatial filter, the two-dimensional temperature field in a methane-air flame can be quntitatively measured. Veriation relationships of flam temperature with high above and distance from the centre of a furnace face were given and discussed. Compared to the results of CARS, the uncertainty of the temperature field in the measurement is less than 5%. |
