摘　　要：为快速评价卷烟加料均匀性,依据标记物1,2-丙二醇近红外光谱信息的特征,建立了基于1,2-丙二醇近红外预测模型的卷烟加料均匀性快速测定方法。研究表明:模型的决定系数R2>0.95,对盲样预测相对误差基本小于5%;测定了3个牌号卷烟,其加料均匀性系数分别为87.9%、89.1%和90.9%,RSD<3%。Based on spectral signature of 1,2-propylene glycol,NIR prediction model was established by Partial Least Squares（PLS） to evaluate casing uniformity.Results showed that the model＇s R2 was higher than 95.00% and RMSECV was below 0.500 and relative error of blind prediction was below 5%.Three cigarette brands were determined and the casing uniformity coefficient were 87.9%,89.1% and 90.9%,respectively,with RSD 3%.
