用小波阈值法处理含噪毛细管电泳分析信号,消除其中的噪声,重点比较了强制阙值法,默认阈值法和给定软阈值法3种小波重构阈值消噪方法的处理结果及各自特点,并详细叙述了分解层数的选择,通过实验提出对毛细管电泳分析信号进行处理的最优条件。 Wavelet thresholding method was used to deal with the signals of the capillary electrophoresis with noises, and the noise was eliminated. The results of the three denoising methods based on the thresholds of the mandatory threshold method, the default threshold method and the given soft threshold method were compared. The choice of decomposition level is described in detail, and the optimal conditions for the signal processing by capillary electrophoresis are proposed through experiments.
