基于多变异分析的烟支物理质量影响因素研究

为提升烟支物理质量的均质化水平,运用嵌套析因设计,考察分析了卷制生产过程中5 个可能的变异来源(班别、班次、卷烟机台、烟丝批次和抽样时间)对烟支物理质量稳定性的影响。结果表明:①卷烟机台和烟丝批次是显著影响烟支物理指标、样本方差和样本广义方差的变异源;②在烟丝物理质量一定的情形下,同一卷烟机台对烟支物理指标的影响不随抽样时间变化;③班别、班次不是显著影响烟支物理指标、样本方差和样本广义方差的变异源。因此,为了使卷制过程烟支物理质量均匀、稳定,要提升烟丝批次内和批次间的物理质量稳定性,提升同类型卷烟机间工作状态的一致性。 

Study on Influencing Factors of Physical Quality of Cigarette Based on Multi-variation Analysis

In order to improve the consistency of physical quality of cigarettes, the effects of five factors (operator, shift, cigarette maker, batch of cut filler and sampling time) on the stability of physical quality of cigarettes were analyzed with nested factorial design. The results showed that: 1) Cigarette maker and batch of cut filler were the main variables affecting the physical indices, sample variance and sample generalized variance. 2) For the cut filler of constant physical quality, the influence of the same cigarette maker on cigarette physical indices did not vary with sampling time. 3) Operator and shift were not the variation sources affecting the physical indices, sample variance and sample generalized variance significantly. Therefore for pursuing higher consistency and stability of cigarette physical quality, it is essential to promote, the intra- and inter-batch consistency of physical quality of cut filler and the consistency of working states of cigarette makers.
