| 摘 要： | 该文提出了一种新的传递方法模型--波长筛选结合直接校正法(WSDS).首先利用样品的性质信息筛选出最有代表性的波长点信息,然后用直接校正法消除这些信息中包含的仪器间差异,以预测标准偏差(SEP)考察模型传递的效果.利用此算法对航空煤油的近红外光谱分析模型在不同仪器之间进行传递研究.经WSDS校正后,对航空煤油密度预测的...

| Abstract: | In this paper,a wavelength selection-direct standardization(WSDS) algorithm was proposed for calibration transfer of NIR model.The WSDS is one of the modifications of direct standardization(DS).In WSDS,only the wavelengths which were highly correlated with the sample property were selected for correcting the variations of the instrumental responses of two different NIR spectrometers.The corrected spectroscopic data were then used to build the model for analysis.The application of WSDS algorithm to calibrati... |
