【Abstract】 The two methods of measuring wood fiber length by near infrared spectroscopy and by traditional means are compared.Experimental method and operating approach of measuring wood fiber using near infrared spectroscopy were introduced in detail which include the choice and the processing of wood samples,collection of near infrared spectroscopy,measurement of experimental value of wood fiber length,analysis of multivariable data and establishment of model.The result shows that the near infrared(NIR) spectroscopic technique could be used to rapidly and accurately predict the wood fiber length of two broadleaf.更多还原
