将小波变换在信号和图象处理过程中边缘检取的思想方法引入到化学中，以确定电位滴定的终点，能直接对测量的数据进行处理，不会引入人为的误差因素．计算精度可达实验精度的下限，且处理结果的判断非常简便．用本方法对实验数据进行处理，获得满意的结果．
The idea of using wavelet transform for edge detection in signal and image processing is introduced into chemistry to determine the end point of potential titration and to process the measured data directly without introducing artifacts of error. Calculation accuracy up to the lower limit of experimental accuracy, and the judgment of the treatment results is very simple. Using this method to deal with the experimental data to obtain satisfactory results.
