摘      要：正 This research evaluated the feasibility of Fourier transform near infrared （FT-NIR） for quantification soluble solids content （SSC） and titratable acidity （TA） in intact pears. Partial least squares （PLS） calibration models, obtained from several preprocessing techniques （smoothing, derivative, etc） in different wavelength ranges were compared. The best models
