梗签含量和尺寸对卷烟物理指标的影响及预测研究OA

[Objective]To investigate the effects of stem piece content and size on cigarette physical indicators and their underlying relationships.[Methods]Conventional cigarettes were used as the research object,and gradient groups varying in stem piece content and size were prepared.Three-dimensional reconstruction was employed to quantify the internal component content.Correlation analysis and the CRITIC(Criteria Importance Through Intercriteria Correlation)weighting method were applied to evaluate the effects of stem piece parameters on cigarette physical indicators.Additionally,an extreme gradient boosting(XGBoost)model was constructed to predict these indicators.[Results]Larger stem piece size resulted in lower stability of stem piece content in cigarettes.Stem piece content exhibited highly significant positive correlations with cigarette weight,hardness,and porosity,a significant positive correlation with circumference,and a significant negative correlation with open draw resistance.When the stem piece content was 4%and the air damper of the cigarette maker was fully closed,the cigarette physical indicators showed optimal stability and comprehensive scores.The coefficients of determination(R2)of the optimized XGBoost models for cigarette weight,hardness,and porosity were 0.953 1,0.950 3,and 0.875 3,respectively,indicating high predictive accuracy and significant model improvement.[Conclusion]Stem piece content was positively correlated with cigarette weight,hardness,and porosity,and these three indicators could be accurately predicted using the XGBoost model.
