本研究比较漫反射和全透射两种检测方式对南丰蜜桔（薄皮型水果）可溶性固形物（ SSC）检测精度的影响。采用QualitySpec型可见/近红外光谱仪采集南丰蜜桔样本的可见/近红外漫反射和全透射光谱，并应用3种建模方法建立相应的南丰蜜桔SSC模型。研究结果表明，检测方式对南丰蜜桔SSC的检测精度影响大，全透射检测方式明显优于漫反射检测方式。漫反射和全透射检测方式的最优南丰蜜桔SSC预测模型的相关系数和预测均方根误差（ RMSEP）分别为0．933、0．601％和0．973、0．381％。与漫反射检测方式相比，全透射检测方式建立的最优SSC预测模型的RMSEP下降了41％～52．8％。

The objective of this study was to investigate the effects of diffuse reflectance and full transmis-sion detection modes on the accuray of predicting soluble solid content (SSC) in Nanfeng mandarin fruit.Visi-ble/near infrared ( Vis/NIR) diffuse reflectance and full transmission spectra of Nanfeng mandarin fruit sam-ples were acquired by a QualitySpec spectrometer ,and three calibration methods were used to develop calibra-tion models of SSC of Nanfeng mandarin fruit at two detection modes .The results indicated that the effect of de-tection mode on the accuracy of predicting SSC in Nanfeng mandarin fruit was significant ,and the full transmis-sion mode was superior to the diffuse reflectance mode .The correlation coefficients and root mean square errors of prediction ( RMSEPs) in best prediction models for defecting SSC in Nanfeng mandarin fruit for diffuse re-flectance and full transmission modes were 0.933,0.601%and 0.973,0.381%,respectively.Compared with the diffuse reflectance detection mode ,the RMSEP of the best SSC prediction model for full transmission detection mode dropped by 41%-52.8%.
