摘 要：在叶丝重量不变的前提下，本文采用均匀试验设计法，对梗丝掺配比例和再造烟叶掺配比例进行试验设计，再将掺配比例与试验样品的常规化学成分进行二元线性回归分析。结果表明，梗丝掺配比例与烟碱含量、钾氯比存在极显著的负相关性，与氯含量、糖碱比存在极显著正的正相关性;总糖和还原糖含量差值与梗丝掺配比例和再造烟叶掺配比例有极显著的相关性，可将总糖和还原糖含量差值作为特征指标建立掺配比例验证模型。

Abstract： Under the premise of constant tobacco leavesweight， a uniform experimental design method was used to design the blending ratio of tobacco stem and reconstituted tobacco leaves， and the binary linear regression analysis was performed on the blending ratio and the conventional chemical composition of the samples in this paper. The results showed that the blending ratio of tobacco stem had extremely significant negative correlation with nicotine content and potassium-to-chlorine ratio， and had extremely significant positive correlation with chlorine content and total sugar-to-nicotine ratio; the value of total sugar contentminus reducing sugar content had a very significant correlation with the blending ratio of tobacco stem and the blending ratio of reconstituted tobacco leaves， the value of total sugar content minus reducing sugar content could be used as a characteristic index to establish a blending ratio verification model.

卷煙中烟梗和再造烟叶常作为掺配物用于降低卷烟烟碱和焦油含量，同时还可有效降低卷烟成本。在卷烟生产过程中，烟梗和再造烟叶加工成丝后均匀地加入叶丝中。烟草物料的混合效果越好，卷烟成品的物理和感官质量的稳定性越好。但烟梗和再造烟叶在感官质量方面表现出木质气稍重、余味残留、刺激性稍大等缺点，因此，常将烟梗和再造烟叶以一定比例添加于中、低档卷烟产品中，在保证卷烟产品感官质量协调的同时达到减害降焦的目的。

烟草常规化学成分（还原糖、总糖、烟碱、氯、钾、总氮）是表征烟草质量的常规检测项目[1]，有研究表明，烟草常规化学成分对烟草感官质量、卷烟主流烟气指标等有较大的影响[2-3]。烟叶、烟梗、再造烟叶的常规化学成分存在差异，可以利用混合物中某组分性质差异评价混合均匀度[4]。……
