摘　　要：为更好地评价细支卷烟物理质量,采用相关性分析和主成分分析方法,分析了200批次细支卷烟的单支质量、吸阻、硬度、通风率、端部落丝率、空头率等质量指标,建立了细支卷烟物理质量综合分析评价方法。结果表明:①通过主成分分析共提取了3个主成分(PC1:32.301%、PC2:30.623%、PC3:13.774%),其方差累积贡献率为76.699%,其中PC1反映指标的偏差率,PC2反映指标的变异系数,PC3反映端部落丝率和空头率;②建立了卷烟物理质量评价模型,将卷烟物理质量评价得分划为优、良、中、差4类档次;③通过模型的应用评价,其中样品8#得分最高为93.02,质量档次为优,样品15#得分最低为59.94,质量档次为差,根据各样品得分情况,能够直观反映和评价不同批次、机台、班组等的细支卷烟物理质量情况。In order to better evaluate the physical properties of slim cigarettes,correlation analysis and principal component analysis(PCA)were used to analyze a series of indexes such as cigarette weight,draw resistance,hardness,ventilation rate,tobacco loss from cigarette end,and percentage of loose end cigarette from 200 batches of slim cigarettes.A comprehensive method for evaluating the physical properties of slim cigarettes was established.The results showed that:(1)Three principal components were extracted by PCA(PC1:32.301%,PC2:30.623%,PC3:13.774%),and their cumulative contribution rate of variance was 76.699%.Among them,PC1 reflected the deviation rate of the indexes,PC2 reflected the coefficients of variation of the indexes,and PC3 reflected the tobacco loss from cigarette end and the percentage of loose end cigarette.(2)A cigarette physical property evaluation model was established,and the cigarette physical property scores were classified into four categories:excellent,good,moderate,and poor.(3)Sample 8#had the highest score of 93.02 and belonged to the excellent quality category,while sample 15#had the lowest score of 59.94 and belonged to the poor quality category.Based on the scores of the test samples,the physical properties of slim cigarettes from different batches,machines and shifts could be systematically evaluated.
