| 摘 要： | 拉曼光谱体现了物质中不同分子基团的振动情况,可以精确地进行物质的定性和定量分析.凭借着这样的优势,拉曼光谱技术已经成功应用在化工生产、管道传输、生化反应监测等工业在线分析领域.然而,在线拉曼分析很容易受到宇宙射线的干扰.宇宙射线在拉曼谱图上体现为一系列峰宽较窄的尖锐的峰,也被称为spike.这些spike使待测物质的拉...

| Abstract: | As a fingerprint of substance,Raman spectroscopy has become a good solution for online monitoring and been widely used in chemical industry and biological engineering.However,online Raman monitoring is easily disturbed by cosmic rays which lead to sharp and narrow cosmic spikes in the Raman spectra.These spikes can pollute or even distort the normal Raman signals.A simple spike removal algorithm based on moving window correlation analysis,absolute residual spectrum analysis and local linear approximation is... |
