根据小波变换对信号的时频特性，用Ｄａｕｂｅｃｈｉｅｓ小波成功地解决了ＸＰＳ荷电位移的确定问题，并应用于铝合金表面锂盐化学转化层组成的定性分析，所得结果与相关文献推测吻合。方法简单易行。
According to the time-frequency characteristics of wavelet transform, Daubechies wavelet was used to solve the problem of XPS charge displacement successfully. It was applied to the qualitative analysis of chemical conversion layer of lithium salt on aluminum alloy. The obtained results were in good agreement with the relevant literature. The method is simple and easy.
