| 摘 要： | 为了得到白酒工业中酒精度的快速检测技术，将偏最小二乘法与傅立叶变换近红外光谱相结合，通过解析白酒样品的近红外光谱图和对光谱进行不同的预处理，结果表明：用最大最小归一化法预处理光谱，光谱范围选择9747.1～7498.3 cm-1和6102～5446.3 cm-1，采用内部交叉验证建立模型，决定系数(R2)为99.99%，交互验证均方根差(RMSECV)为0.165%，主成分数为4，此条件下建模效果较好；模型进行验证结果表明预测集相关系数(R2)为99.80%，预测标准偏差(RMSEP)为0.264%，模型的预测效果很好，具有较高的精密度和良好的稳定性，能满足生产中白酒酒精度的快速检测要求。
