Abstract:

The different filling material, including expanded stem, reconstituted sheet and expanded tobacco,was filled into cigarette to study the relation between mixed filling material and smoke indexs, the experment data was analysed with the method of correlation analysis, variance analysis and regression analysis.The correlation analysis result shows: when three types of filling material was used simultaneously, are notable influnce factors of tar, nicotine and puff,but the quanlity of reconstituted sheet and expanded tobacco are unnotable factors. variance analysis result shows: the mixing model of filling material is also unnotable factor.So three factors, the quanlity of expanded stem, total quanlity of filling material and cigarette weight, were selected to set forecasting model with themethod of regression analysis, acording to these model, the forecasting reeor of tar, nicotine and puff is about ±1.60mg/cig、±0.28 mg/cig、±1.66 mg/cig、±0.69puffs/cig。
