摘要： 对小波包分析的算法进行了改进,并将此算法成功地应用于多组分重叠色谱信号的解析.结果表明,本文提出的算法解决了MRSD算法的不足,更适合处理分析化学信号,用于重叠信号的解析时不需重构(逆变换),简化了数据处理步骤,加快了数据解析速度,具有较强的解析能力.对于重叠色谱信号的解析,小波包分析比小波分析具有更强的解析能力.

Abstract: Anovel algorithm of the wavelet packets analysis, which is more suitable to process the practical signals in analy ticaLInst rument al analysis, was proposed based on The algorithm of the multiresolution signal decomposition(MRSD).And application of the method to The resolution of The overlapping multicomponent chromatogram was invest igated.It is proved by The results that The method is superior to the MRSD in resolving overlapping chromatograms and There is no need to perform The inverse transform.Comparing with The results by wavelet analysis, The wavelet packets analysis possesses stronger ability in resolving overlapping analytical signals.The linearity of chromatographic signal remains in The resolved results, which ensure the results can be used for quantitative determ ination.

Key words: Wavelet packets analysis, Wavelet analysis, Resolution of overlapping signals
