改进BP网络在联邦镇咳露复方制剂分析中的应用

Application of the Modified BP Network in the Analysis of Lianbang Zhenkelu

利用改进ＢＰ网络同时测定了镇咳新药联邦镇咳露中的三组分含量，考察了网络拓扑模型对于分析结果的影响，通过选择合适的网络参数，同时测定模拟样品中的三组分，其中磷酸可待因、扑尔敏和盐酸麻黄碱的平均回收率分别为１００．０３％，１００．１０％和１００．０７％，相对标准偏差分别为０．５４％，０．６５％，０．５１％；与非线性偏最小二乘法结果相比，本文结果更为满意。

The effect of network topologic structure on the analytical result and calculating ability in the determination of the three components in Lian bang Zhenkelu by using modified BP network is studied. Experimental result indicates that proporal network parameter helps to determine simultaneously three components in the simulated sample. The average recoveries of codeine phosphas, chlorpheniraminum and ephedrini hydrochloridum only 100.03%, 100.10%, 9910% respectively. The relative standard deviations are 0.54%, 0.65% and 0.51%, respectively.
