| 摘 要： | 以云南优质烤烟为实验材料,在国产光栅漫反射型近红外仪器上,比较研究了不同年份样品建模、不同化学值分布建模对近红外检测结果的影响.结果表明:总糖、尼古丁组分模型偏差受年份影响较大,总氮组分模型偏差与样品年份关系不明显.烤烟组分的不同化学值分布建模结果表明:用化学值按自然正态分布的样品建立模型的结果优于按均匀分布建模的结果.该研究对从大量天然产物样品中挑选代表性样品时所采用的挑选方法和原则具有指导性的参考价值. |

| Abstract: | The influence of sample annum and the distribution of sample component on NIR veracity was studied with homemade grating diffuse NIR instrument using Yunnan flue-cured tobacco.Results showed that sample annum had an obvious influence on the total sugar and nicotine models,but had an unconspicuous influence on the total-nitrogen model.Models set up by samples,whose component content distribution was normal school,was better than those set up by even distribution.The conclusion in this study has a significant referenced value for the method and principle to select representative samples to modeling from a large amount of specimens. |
| Keywords: | NIR Flue-cured tobacco Sample annum Distribution of chemical value |
