云南烟叶主要化学及烟气成分拟合分布研究

Study on Fitting Distribution of Main Chemical and Smoke Components in Tobacco Leaf of Yunnan

对云南151个烟叶收购站点571份样品进行化学及烟气成分数据的拟合分布研究,结果表明,少数化学成分数据较接近正态分布;但是,多数化学成分按总体、地区、品种和部位分类,其分布状态都不完全是正态分布,多为非正态分布;某些化学及烟气成分的总体状态为正态分布时,而地区、品种和等级分布状态可能是正态分布也可能是非正态分布。

The fitting distribution of chemical and smoke components in 571 samples was studied which are collected from 151 tobacco stations in Yunnan.The results showed that a small number of chemical components are closer to normal distribution; while most of chemical components are not completely normal distribution according to general,region,variety and part distribution status; some chemical and smoke components which are according to general are quite close to the normal distribution,but these which are according to region,variety,grade are quite close to the normal distribution or non-normal distribution.
