摘　　要：介绍了一种用有理样条函数法确定酸碱电位滴定终点的新方法。说明了方法的原理和算法。给出了用该法测定极弱酸（硼酸和苯酚）的实验结果，并与经典方法进行了比较。结果表明，本文提出的方法准确、可靠、快速。A method is described for the determination of end-points of acid-base potentiometric titration by using rational spline function. The principle and algorithm of the method are explained. The very weak acids (orthoboric acid and phenol) were determined with satisfaction. The experimental results show that the new method is accurte and comparable with traditional method.
