摘要
用傅里叶变换红外光谱仪（ＦＴＩＲ），在１５５０～６６０ｍｃ－１波数范围内，采用化学计量学的偏最小二乘法（ＰＬＳ），测定汽油的辛烷值（ＲＯＮ）、密度、馏程（５０％、９０％）、芳烃、烯烃等质量性质。试验结果表明，实验室标准方法测定的真值和红外光谱预测值的相关性好，检验结果符合国家标准方法的再现性要求。
Combined with the partial least square regression, the octane number (RON), density, temperature evaporate (50%,90%), aromatics and olefin concentration of gasoline were determined by the Fourier transform infrared spectroscopy at the wavenumber region of 1550 similar to 660cm(-1). The experimental results showed that the actual values measured by the standard method were agree with the prediction values by the proposed method.
