摘　　要：研究了用小波变换确定电位滴定终点方法测定硼酸和苯酚两种极弱酸,同经典方法及其它数学方法的结果进行比较,说明用小波变换电位滴定法测定极弱酸快速、准确,可为极弱酸的计算机联机测定提供一种新的途径.A novel method for finding of end points of acid-base potentiometric titration by using wavelet transform strategy was developed to determination of amount of very weak acids of orthoboric acid and phenol. The comparison of the results obtained by proposed method and the conventional methods or rational spline function method showed that the wavelet transform technique in combined with potentiometric titration method for determination of very weak acid has the advantage of rapidity and accuracy. It may provide a new way for automatic titration of very weak acids using potentiometer with computer.
