摘　　要：为研究不同烟草原料物理保润性能的差异性,以国内具有代表性的烤烟、薄片、膨胀梗丝、白肋烟、香料烟为研究对象,以含水率测试手套箱法为检测手段,以Weibull模型拟合失水过程水分比随失水时间变化曲线、模型中特征时间参数α值大小,作为物理保润性能差异性的评价指标.结果表明:Weibull模型能够较好地用于表征烟草样品干燥动力学;不同部位烟草物理保润性能顺序为:中部>上部>下部;不同品种烟草物理保润性能顺序为:K326>红大>云烟87;不同类型烟草物理保润性能顺序为:云烟87 C3F>膨胀梗丝>香料烟>薄片>白肋烟;冻干后的烟草样品比平衡水分样品物理保润性能要好.In order to investigate moisture retention of different leaf tobacco materials,the moisture retention of flue-cured tobacco,tobacco sheet expanded stem burley tobacco and oriental tobacco were detected by the moisture content testing glove box. With water losing time fitting curve in water losing process by Weibull model and characterization time parameter α as indicators of material mositure retentivity. The results showed that： Weibull model could be well used for characterization of tobacco samples drying dynamics; The moisture retentivity in different stalk positions of tobacco： middle upper bottom; The moisture retentivity in different varieties were as follows： K326 〉Hongda 〉Yun87; The moisture retentivity in different types of tobacco were as follows： Yun87 C3 F〉 expanded stem 〉oriental tobacco tobacco stem burley tobacco; The material moisture retentivity of freeze-dried sample was better than that of the equilibrium sample.
