人工干预的傅立叶变换红外光谱差减技术在大气毒物分析中应用

The Application of Fourier Transform Infrared(FT-IR)Spectrum Subtraction with Artificial Intervention in the Determination of Air Toxics

采用人工干预的傅立叶变换红外光谱差减技术对混合气体中大气毒物进行定量分析，并对其实验条件进行了详细研究和优化，误差在８％以内。同最小二乘法、因子分析法相比，本法无需知道样品全部定性信息，即可进行定量。

In determination of air toxics in gas mixture the FT-IR spectrum subtraction with artificial intervention is used and the experimental condition is optimized with a result of 8%deviation.In comparision with leastsquares and factor analysis,this method is superior in respect of no need of the total qualitative informations.
