title: [Adopting the method of correlation coefficient to improve the accuracy of the xylene isomer's prediction model].
abstract: This paper focuses on the detailed researches on the correlation coefficient in near infrared spectrum and points out its characteristics in multi-component solution; the paper also proves the principle of obtaining more accurate results when using high correlation coefficient for model building, and presents a practical experiment to test the conclusions by using para-xylene, meta-xylene, and orthoxylene's mixture.
