摘　　要:近红外光谱分析建模中存在多变量高维数据处理问题,导致计算量大,不利于过程控制中应用.为此提出利用小波变换压缩近红外光谱数据的算法与准则,并结合柴油十六烷值定量分析研究压缩数据的建模效果.研究表明,经小波方法处理后,变量维数压缩30倍左右,光谱主要信息基本保留,而模型的预测精度和常规预处理方法分析相比有明显提高.光谱数据压缩的同时包含了噪声滤除和基线校正,简化数据处理步骤,有利于NIRS实际应用时提高建模效率. (共6页)

关 键 词:近红外光谱 小波变换 数据压缩 十六烷值.

Description/Abstract A near-infrared (NIR), advanced control system has been controlling the gasoline blender at BP France's Lavera refinery for more than 2 years. The blender produces 1 million metric tons/year gasoline (about 21,000 b/d) using multivariable blend-control software in a closed-loop mode. BP's system uses a centralized NIR spectrometer fitted with optical fibers that carry NIR radiation between the instrument and process streams. The analyzer monitors the product stream from the blender and transmits data to the control software, which adjusts the component flow rates to meet target specifications. The system computes blending indices using an innovative approach based on the NIR response of the individual basestocks. The paper discusses NIR analysis, blending optimization, the Lavera project, BP methodology, data treatment, system assessment, and benefits.

Abstract“Real-time” chemometrics as envisioned by the union of instrument control, data acquisition, and chemometric analysis with a single software platform can provide substantial benefits to manufacturing concerns that require process control. Some of these benefits include faster generation of information and improved quality control. This paper describes a series of chemometric routines written in LabVIEW and demonstrates their use in predicting six properties of diesel fuel. In particular, near-infrared spectral data were used to predict the boiling point at 50% recovery, cetane number, density, freezing temperature, total aromatics, and viscosity for a series of diesel fuels.

谢谢上面两位，不过我不是需要这方面的文章，而是用仪器检测出来的数据。
