| 摘 要： | 在双色法测试系统的标定和改善测量计算精度方面进行了有益的尝试， 验证了测试系统的良好线性，并利用自行装配的燃油炉和双色法测试系统对 燃油炉火焰温度和吸收系数进行了测量．结果表明，对火焰温度进行测量计 算时，在一定条件下可以忽略壁面反射和辐射的影响，而对单色辐射率、单色 吸收系数和碳粒浓度的测量则必须考虑它们的影响．

| Abstract: | The authors have made an attempt at improving the bright temperature calibration and calculation accuracy in the two-colour method measurements, verified the linearity of the measurement system and presented some reasonable results obtained from the measurments of an oil-burnt furnace with the measurement system prepared for the measurements. The results show that the effects of wall reflection and wall radiation on the measurement calculations of flame temperature can be omitted under some conditions, hut on the measurements of monochromatic radiativity, monochromatic absorption coefficient and soot density must he considered. |
