摘  要：
为探索打叶复烤片烟结构的稳定性,选取全国20家打叶复烤企业的成品片烟样品共295份,运用灰色统计法研究了片烟样品的11项结构指标,结果表明:中片率和小片率最易偏离指标要求,属不稳定指标;含末率、粗梗率、>12.7mm叶片率、>6.35mm叶片率和>3.18mm叶片率稍易偏离指标要求,属稍稳定指标;含水率、大片率、碎片率和叶含梗率不易偏离指标要求,属稳定的指标。运用方差分析对统计系数进行检测,验证了指标值域选择的合理性。打叶复烤企业和卷烟工业企业在进行过程稳定控制和打叶质量评价时要及时提高中片率,降低小片率,兼顾稍稳定指标,保持稳定的指标。

摘  要：
In order to explore the stability of lamina structure of threshing and redrying,eleven structure indexes of 295 samples from twenty tobacco redrying factories were analyzed by grey statistic analysis method.The results showed that percentage of middle lamina(12.7-25.4 mm) and percentage of small lamina(6.35-12.7 mm) belonged to unstable indexes,which most deviated from the target requirement.Dust rate and crude stem rate and the content of long particle(>12.7 mm) and the percentage of lamina(>6.35 mm) and the percentage of lamina(>3.18 mm) belonged to slightly stable indexes and more deviated from the target requirement.The variation of moisture content and percentage of large lamina(>25.4 mm) and fine particle content(1-6.35 mm) and stem content in lamina were stable,which accorded with requirements.The grey statistical coefficient was tested by Variance Analysis,thus the indexes threshold value should be reasonable.The percentage of middle lamina should be improved and percentage of small lamina should be decreased mainly and the slightly stable indexes should be paid attention to and the stable indexes should be continued for quality evaluation and process control.
