摘　　要：为找到中支卷烟适宜的烟丝形态,以烟丝特征长度表征烟丝形态,采用烟丝形态调控技术,分析了中支卷烟烟丝不同特征长度与质量指标及稳定性关系。结果表明:①烟丝特征长度在2.35~2.85 mm(卷制前)范围内,中支卷烟物理指标稳定性较好;②空头率、烟支密度标准偏差和密度分布一致性系数η值均随特征长度减小呈先降低后增大的趋势。③当烟丝特征长度在2.35~2.80 mm(卷制前)范围内,卷制烟支样品端部落丝量较小、燃烧锥落头倾向较低,但动态吸阻分布一致性存在波动。④综合分析,考虑到配方间差异,中支卷烟烟丝特征长度在2.35~2.85 mm(卷制前)范围内,辊筛频率在37~47 Hz之间,物理指标稳定性、烟支密度一致性较好,空头率和燃烧锥落头倾向较低,端部落丝量较小。In order to evaluate suitable morphology for cut tobacco strands in demi-slim cigarettes,the morphology of cut tobacco strands was characterized by the characteristic length.The relationships of the characteristic length with the quality indexes and consistency of finished demi-slim cigarettes were analyzed with tobacco morphology control technology.The results showed that:1)When the characteristic length of tobacco strands(before rolling)was in the range of 2.35-2.85 mm,the consistency of physical indexes of the cigarettes was better.2)The loose end percentage,density standard deviation and density distribution consistency coefficientηof the cigarettes all decreased first and then increased with the reduction of the characteristic length.3)When the characteristic length of tobacco strands(before rolling)was in the range of 2.35-2.80 mm,loss of tobacco from the end of cigarette and combustion cone falling propensity were lower,and the distribution consistency of dynamic draw resistance fluctuated to a certain degree.4)Considering the differences between tobacco blends,the consistencies of physical indexes and density of demi-slim cigarettes were improved and the loose end percentage,combustion cone falling propensity and loss of tobacco from the end of cigarette were lower when the characteristic length of tobacco strands(before rolling)was in the range of 2.35-2.85 mm and the frequency of roll screen was between 37-47 Hz.
