南丰蜜桔可溶性固形物近红外特征波段选择（Selection of NIR Characteristic Wavelength Bands for Soluble Solids Content in Nanfeng Mandarin Fruit）
南丰蜜桔 可溶性固形物 近红外光谱 间隔偏最小二乘法
2009/8/11
探讨了在350～1800nm波段范围内不同光谱预处理方法对提高模型预测能力和稳定性的作用，但其效果不如间隔偏最小二乘法显著。通过间隔偏最小二乘特征波段选择方法，确定了南丰蜜桔可溶性固形物特征波段为：642～787nm、861～1006nm、1080～1152nm和1226～1371nm。采用30个未参与建模的南丰蜜桔样品，预测特征波段建模模型，预测模型的相关系数为0.95，预测均方根误差为0.55...
