本文将近红外光谱法与偏最小二乘法(PLS)结合,对生理盐水中的NaCL浓度进行快速分析,建立了最佳数学校正模型。讨论了光谱的预处理方法和主成分数对PLS定量预测生理盐水中NaCL浓度的影响,并对预测集样品含量进行预测,结果令人满意。
In this paper, near-infrared spectroscopy combined with partial least squares (PLS), NaCL concentration in saline for rapid analysis, the establishment of the best mathematical correction model. The effects of spectral pretreatment methods and principal components on the quantitative prediction of NaCL concentration in physiological saline by PLS are discussed. The prediction of the sample concentration in the prediction set is satisfactory and the results are satisfactory.
