摘　　要：本文以火焰光谱辐射吸收的指数宽带计算模型为基础，推导出火焰组分浓度的红外光谱诊断的原理公式，并利用所建立的诊断系统进行了实验研究，诊断精度优于１０％。In this paper, the principle formulas of infrared spectroscopy diagnoses for flame species concentration are deduced based on the exponential wide band mode of spectral radiation absorption of gas molecules, and a system of infrared spectroscopy diagnoses has been established. Utilizing the system, the experiment research is carried out, and the results show that the accuracy is higher than ten percent.
