| 摘 要： | 燃烧火焰辐射率对于光学法测量火焰温度具有重要意义。利用消光法测量气体发光火焰中炭粒子的平均体积浓度，结合炭粒子在可见光及近红外区域（５１４．６￣１０６３．３ｎｍ）的折射率，得到火焰辐射的单色辐射率随波长的变化规律。对不同浓度丁烷气体火２此方法所获得的火焰辐射率和在此基础上得到的火焰温度与已有的研究结果较为吻合。

| Abstract: | Determination of flameemmissivity is important for flame temperature measurement by optical method. In thispaper, a study is performed to obtain the average volume concentration of soot particlesin a gas flame by the extinction method. Combined with the refractive index of sootparticles in visible and near infrared wavelength range from 514.6nm to 1063.3nm, theflame monochromatic emmissivities versus wavelength were derived. Studies from differentconcentration butane flames indicated that, the derived flame emmissivities and flametemperatures by this method were in good agreements with those from other studies. |
