摘　　要：气相色谱/质谱法分析主流烟气成分是一种常规有效的技术手段,对于主流烟气稳定性的评价,需先对不同批次不同保留时间的质谱图与标准质谱图对比定性,确定其有效成分后,再根据有效成分的峰面积响应情况,利用夹角余弦、相关系数、欧式距离等方法,进行相似度的评价,不能直接对比原始色谱图数据。且对于主流烟气这类样品来说,其成分极为复杂,难以准确定性定量,人力消耗大,效率不高。本文利用傅立叶变换的方法,将图谱转化为频域数据后,再评价样品的相似度,其客观性、可靠性和时效性优于传统方法。gas chromatography/mass spectrometry analysis of mainstream flue gas composition is a conventional effective technology,for the evaluation of mainstream flue gas stability,need first to different batches of different retention time of mass spectrum and standard mass spectrum qualitative,determine the active component,then according to the peak area response of the active component situation,using Angle cosine,correlation coefficient,European distance,similarity evaluation,can not directly compare the original chromatogram data.And for the mainstream flue gas samples,its composition is very complex,difficult to accurately qualitative and quantitative,human consumption is large,the efficiency is not high.In this paper,using the Fourier transform method,we transform the map into frequency domain data and evaluate the similarity of the sample,and its objectivity,reliability and timeliness are better than the traditional method.
