摘　　要：应用波长为643.26～985.11 nm的Purespect近红外透射光谱仪,分析了储藏时间对吸光度的影响。对不同储藏期寒富苹果的校正集样品进行了各自建模和共同建模,并研究了模型的差异性。结果表明:建立的共同模型预测结果较好,模型的相关系数(RC)为0.948,校正均方根误差(RMSEC)为0.468,预测均方根误差(RMSEP)为0.456,偏差(Bias)为0.027。该模型扩大了校正集样品化学成分含量的范围,提高了模型的适用范围,能满足实际生产要求。The influence of storage time on the absorbance was studied by Purespect Near infrared transmittance spectroscopy using the wavelength between 643.26 -985.11nm. Each individual model and common models were established for ＂Hanfu＂ apples at different storage time. The differentiation analysis was also conducted. The results showed that the prediction ability of the common model was better than each individule one. The correlation coefficient of the model was 0. 948, RMSEC was 0. 468, RMSEP was 0. 456, and the bias was 0. 027. The common model extended the contents range of chemical components of the calibration samples, and improved the model＇ s application areas and meets the requirements of the actual production.
