大家好，我是论坛新人。在读一篇用ATR检测橄榄油的文章中，他的数据处理用了Absorbance normalized， 原文如下：“Data analysiswascarried out using the full spectra.Meancentering was used to improve the smaller spectral differences removing the common information from the spectra. Absorbance normalized value was also employed. None of the other mathematical treatments (multiplicative scatter correction, second derivative, etc.) or wavelength ranges tested improved the prediction accuracy of models.”
