| Abstract: | Analyze the near infrared spectrum of the glucose concentration using main component regression and partial least square algorithm, build up the adjusting mathematical model. The correlation coefficient of main component regression is 0.9294 while the correlation coefficient of partial least square algorithm is 0.9998. Through comparing the above twos, find the suitable method to analyze the near infrared spectrum of the glucose concentration. |
