拉曼光谱在水质分析中的应用:展望及系统设计 总被引:8,自引:3,他引:5
拉曼散射光谱是一种研究物质结构强有力的工具,目前已经逐渐应用于许多领域,但在水质分析方面的应用讨论尚少。本文首先对拉曼光谱应用于水质分析的可行性及优越性进行了分析,并在此基础上设计了一套新型的应用微机和进经神经网络实现的拉曼光谱水质分析系统,以达到对水质进行高效、准确的定性和定量分析的目的。 相似文献

1. IntroductionIn the paPer [1], where Zhang Hed et al. preseated the nonoocUlatory 3rdorder ENNWence scheme. The idea of ENN scheme is to compare the 1st-order dmerence and 2ndorderWence to attain 3rdorder accurate scheme and to avod spurious oscillatious neax shocks.However the ENN stwe has certain drawbaCks. One Problem is ouly 3rdords accuracyeven in the very smooth regions. AIlOther is to use a 1ot of logical statemeats which dst theconvergence rate and the efficiency Of parallel… 相似文献
