摘　　要：本文根据小波变换不改变信号线性关系的性质，用DOG（DifferenceofGaussians）小波函数处理了Cu－KNO3中Cu2＋的差分脉冲伏安法实验数据，结果延长了测定的线性范围。Based on the property that the waveIet transform does not change the linear relation of signals, Gaussian difference wavelet function has been used for the treatment of differential pulse voltammetric data of Cu2+ in Cu-KNO3 system. The linear range of detection is thus extended.
