| 摘 要： | 近红外漫反射光谱易受样品颗粒度的影响。本文对10种不同粒度的黄连的近红外光谱进行分析,讨论粒度对黄连的近红外光谱强度的影响。结果发现,小粒度黄连的近红外光谱的重现性较好。当黄连粒度小于0.154 mm时,粒度变化对黄连的近红外光谱强度的影响较小。 |
| 关 键 词： | 近红外光谱 黄连 颗粒度 |

| Abstract: | NIR spectroscopy is prone to be influenced by the granularity of the sample.In this paper,the NIR spectra of coptis chinensis of ten different granularities were obtained.The influence on the NIR spectroscopy of coptis chinensis by different granularity was discussed.The NIR spectroscopy of coptis chinensis with smaller granularity is more stable.The influence of granularities on NIR spectroscopy is inconspicuous when the granularity of coptis chinensis is smaller than 0.154 mm. |
| Keywords: | Near infrared spectroscopy Coptis chinensis Granularity |
