摘要
基于烟草样品的近红外漫反射光谱和化学计量学的方法,建立了烤烟中磷酸根的近红外数学模型。结果表明,该数学模型外部验证的平均相对误差在10%以内,说明模型的准确性和稳定性均很好,可以用来快速、准确、无污染地测定烤烟中磷酸根的含量。
The phosphate content in flue-cured tobacco was determined by the near infrared spectroscopy with a mathematical model of phosphate in flue-cured tobacco. The average relative error of the model external verification of the phosphate was with in 10%. The model was accurate and stable and could be used to determinate the phosphate content accurately in flue-cured tobacco without pollution in short time.
