- synthetic calibration sample 等成分标准, 合成校准样品
- The results of calibration sample set showed that the re-correlation coefficients(R2) between NIRS and chemical methods values were 0.99 for CP and the root square standard error of calibration(RMSEC) were 0.34%. 结果指出 :用NIR法得到的预测值与用凯氏定N法得到的测定值间的复相关系数达到R2=0.;99;定标标样的标准误均方RMSEC=0
- Therefore, application of spectrum PCA in the selection of calibration sample set was very efficient and cost effective in routine chemical analysis in the procedure of tobacco NIR mode establishment. 因此,应用光谱主成分分析是烟草近红外模型构建过程中的一种非常有效,且节约常规化学分析成本的校正集样品选择方法。
