| 摘 要： | 以B-样条小波为分析小波，提出了用于分析化学重叠信号解析的新方法——连续样条小波变换，结果表明：连续样条小波变换应用于分析化学信号的处理，能使峰变窄同时还能提高信号的信噪比，是一种新型有效的重叠信号解析方法，能从含噪声重叠信号中直接得到重叠峰的峰数目及其相应的峰位置。

| Abstract: | A novel method,continuous spline wavelet transform(CSWT),was proposed for resolving overlapped peaks.The second-order,third-order and the forth-order B-spline wavelet were used as analyzing wavelet,respectively.It was shown that the peaks after processing were narrower and their signal-to-noise ratio was enhanced in comparison with the overlapped peaks.It was found also that the second-order B-spline wavelet was superior to the other two wavelets.The results obtained for the simulated spectra confirmed that the proposed CSWTwas an effective method for resolving overlapped peaks. |
