摘　　要：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 methods of image processing and edge detection by wavelet transform were introduced into chemistry for determining potentiometric titration end-points.This method was used to deal with the experiment data derectly without introducing artificial error factors in calculation. The accuracy of calculation results can get to the experiment limit automati-cally, and the titration end-points can be determined easily by this method. Very satisfactory results were obtained in the calculation.
