摘要
提出了用均匀设计法安排 Ｂ Ｐ 网络运行参数以进行优化的方法。研究了硝酸盐和亚硝酸盐在紫外区的吸收光谱。利用 Ｂ Ｐ 算法的人工神经网络处理光谱数据，提出关于同时测定水样中硝酸盐氮和亚硝酸盐氮的新方法。对实际水样进行了测定，结果满意。
A new method to optimize parameters has been built for BP network following uniform design. The ultraviolet absorbed spectroscopy of NO\+ -1 \-3 and NO\+ -1 \-2 was studied. On the basis of back propagation algorithm, neural networks were applied to deal with the spectroscopy data.A new method to determine NO\+-\-3 N and NO\+-\-2 N in water samples was proposed. Good results were obtained.
