摘　　要： 以正弦函数为分辨因子与样条小波滤波器相作用 ,使其构成样条小波自卷积法的峰分辨器 ,利用样条小波峰分辨器可以直接分开计算机模拟的不同类型的重叠双峰 ,分峰前后峰面积和峰位置的相对误差均小于5.0 % ;将其应用于电分析化学重叠信号的实验数据处理 ,得到较满意的结果。同时 。 The sinusoidal function as a resolving factor is acted on the filters of spline wavelet and a peak resoluter of spline wavelet self _ convolution is made. Several kinds of simulated overlapping peaks were processed by this peak resoluter and satisfactory results were obtained. Baseline separation can be achieved for systems of arginine-lysine-histidine-proline and Pb(Ⅱ)-Tl(Ⅰ). The relative errors of both peak position and area are less than 5.0%. The electroanalysis overlapping peaks were resolved by this method with satisfactory results. It also provides a new choice for resolving factor of spline wavelet peak resoluter.
