Estimation of Wood Mechanical Properties of Eucalyptus pellita by Near Infrared Spectroscopy
摘要
Abstract
In this study, collecting Eucalyptus pellita plantation as the research object, the mechanical properties of small clear wood samples were studied by national mechanical test methods and near infrared spectroscopy. After collecting the near infrared reflectance spectra of each sample, the spectra were pretreated and the calibration models were developed in different wavelength and validated by prediction set ( one third of whole samples). The results showed that second-derivative pretreatment, 350 - 25 000 nm full spectral wavelength, the mean of spectral value in radial and tangential section were the best in the prediction model for wood mechanical properties of Eucalyptus pellita. The relationships were good between the laboratory-determined mechanical properties values and NIR prediction values of mechanical properties, the correlation coefficients were more than 0. 88, RPD were more than 2. 0. The NIR analysis technique can realize the rapid prediction for the mechanical properties of small clear wood samples of Eucalyptus pellita according to better predicted effect.关键词
