摘　　要： 提出了一种用于提取重叠信号中峰位置的新方法—小波分形峰位法 ,对重叠信号峰位置的提取进行了研究。结果表明 :该法是提取含噪重叠信号中峰位置的有效工具 ,方法简便易行。 A new method called wavelet fractal peak positions method (WFPPM) for extracting peak positions of various overlapping signals with noise by combining continuous wavelet transform and fractal theory is proposed. The differential pulse voltammetric overlapping peaks of the mixture of Cd(Ⅱ) and In(Ⅲ) are processed by this method. The results show that WFPPM is an efficient tool in extracting solo peak position from overlapping signals with noise even in the case of considerable overlap and serious interference of noise.
