摘　　要：【目的】为中支卷烟在线激光打孔参数设计提供参考。【方法】分别采用显微镜和3D显微镜表征中支卷烟接装纸在线打孔的孔形态特征,考察在线打孔脉冲持续时间对中支卷烟理化指标及其稳定性的影响。【结果】①脉冲持续时间过短(≤47µs),出现孔未打透的情况,脉冲持续时间过长(≥90µs),出现椭圆孔的情况。②脉冲持续时间与孔直径、孔面积均呈线性正相关关系。③在线打孔脉冲持续时间与卷烟吸阻、滤嘴通风率和总通风率呈二次函数关系,且决定系数R2均在0.99以上;在线打孔脉冲持续时间与卷烟各项化学指标呈线性函数关系,且决定系数R2主要在0.96以上;卷烟水分释放量与打孔持续时间呈二次函数关系,决定系数为0.9767。④随着孔面积的升高及打孔个数的减小,卷烟的吸阻变化较小,均能保持相对稳定,卷烟总粒相物、烟碱、焦油、CO等释放量的标准偏差在脉冲持续时间适中(50~60μs)时比较小。In order to provide more reference for the design of online laser perforation parameters of medium-size cigarettes,the morphology of ventilation holes created by online laser perforation was characterized by microscope and 3D microscope using both.The influence of pulse duration on the cigarette physical characteristics and routine analysis of mainstream smoke of medium-size cigarettes was investigated.The results show that:①Holes cannot be penetrated when the pulse duration is too short(≤47 seconds).Elliptical holes appear when the pulse duration is too long(≥90 seconds).②The pulse duration showed a linear positive correlation with the diameter and area of ventilation holes.③The pulse duration of perforation is inversely proportional to cigarette suction resistance,filter ventilation rate and total ventilation rate,and the determination coefficient R2 is above 0.99;the pulse duration of online laser perforation is linearly related to various routine analyses of mainstream smoke,and the determination coefficient R2 is mainly above 0.96.The moisture release in mainstream smoke was quadratically related to the pulse duration of perforation,with a coefficient of determination of 0.9767.④With the increase of ventilation hole area and the decrease of the number of ventilation hole,the change in draw resistance of cigarettes is minimal,which remains relatively stable.The standard deviation in the release of total particulate matter(TPM),nicotine,tar,and CO was relatively small when the pulse duration was moderate(50 to 60 s).
