文山烟叶均质性评价方法研究

摘要

[目的]筛选烟叶均质化评价中数据处理方法.[方法]对比变异系数法、方差分析法和数据标准化后方差分析3种方法, 通过对文山州烟叶质量进行均质性评价, 分析3种方法的优缺点.[结果]变异系数法简单快速, 但无法比较大小, 也无法判断偏离方法;方差分析法可以克服变异系数法的缺点, 但受干扰太多;数据标准化后方差分析法, 可以克服上述方法的缺点.3种方法中变异系数法的评价方法与其他2种方法差别较大;方差分析法和数据标准化后方差分析法评价结果基本一致稍有不同.[结论]数据标准化方差分析法可以作为烟叶均值性的评价方法.%[Objective] The research aimed to screen data processing methods in tobacco leaves homogenization evaluation.[Method]This study compared the three methods of variation coefficient, variance analysis and standardized post variance analysis, and the advantages and disadvantages of the three methods were analyzed by comparing the evaluation of homogeneity of tobacco leaves quality in Wenshan. [Result]The variation coefficient method was simple and fast, but it could not compare the size and could not judge the deviation method; variance analysis method could overcome the shortcomings of the variation coefficient method, but was too much interference; standardized post variance analysis could overcome the shortcomings of the above methods. The evaluation method of the variation coefficient method was quite different from the other methods, and variance analysis method and standardized post variance analysis were basically consistent and slightly different. [Conclusion] Standardized post variance analysis can be used as an evaluation method for homogenization of tobacco leaves.
