使用改进的BP算法 ,避免了可能产生的麻痹现象 ,对几处酸及烷基磷酸酯及深井水样的电位滴定曲线进行拟合 ,用少量的实验数据恢复了大量的体系信息 ,并用曲线一次微商极大值确定电位滴定终点。
Using the improved BP algorithm, the potential paralysis was avoided. The potentiometric titration curves of several acids and alkyl phosphates and deep well water samples were fitted. With a small amount of experimental data, a large amount of system information was recovered and the curve was used once The maximum of the derivative determines the end point of titration.
