Comparative analysis of different methods for measuring the volume of expanded tobacco stem before and after rejuvenation

摘要: 为定量分析膨胀烟梗回潮前后体积的变化,利用自然堆积法、填充法、液体浸渍法3种常用方法,分别对膨胀烟梗回潮前后体积进行测定、比较和修正,同时将体积修正结果应用于膨胀烟梗回潮后体积的计算并进行验证分析.结果表明:相对于自然堆积法和填充法,液体浸渍法测定膨胀烟梗回潮前后体积的结果更为真实可靠,数据波动小,稳定性好.以液体浸渍法测定结果为标准,建立液体浸渍法(y)与自然堆积法(x1)、填充法(x2)之间的线性关系,修正结果表达式为y=0.352x1-41.744,y=0.772x2-19.874,相关系数R2分别为0.922和0.959.修正后的自然堆积法和填充法测得膨胀烟梗回潮后体积结果接近于液体浸渍法,较修正前的结果更准确.这表明3种方法均可用于测定膨胀烟梗体积,但自然堆积法和填充法的测量结果需通过液体浸渍法进行修正后方能获得较为准确的结果.Abstract: In order to quantitatively analyze the volume change of expanded tobacco stem after rejuvenation, the natural accumulation method, filling method and liquid impregnation method were used to measure, analyze and modify the volume of expanded tobacco stem after rejuvenation. At the same time, the correction results of volume were applied to calculate the shrinkage rate of expanded tobacco stem after rejuvenation. The results showed that the liquid impregnation method was more reliable in measuring the volume of expanded tobacco stem after rejuvenation with less fluctuation of data and good stability when compared with natural accumulation and filling method. Based on the results of liquid impregnation method, the linear relationship between liquid impregnation method (y) and natural accumulation method (x1) and filling method (x2) was established. The modified expressions were that:y=0.352x1-41.744, y=0.772x2-19.874, and the correlation coefficients R2 were 0.922 and 0.959, respectively. The volume of expanded tobacco stem after rejuvenation by modified natural accumulation method and filling method was close to that by liquid impregnation method, which is more accurate than that before amendment. The results showed that all three methods could be used to measure the volume of expanded tobacco stem, which need to be modified by liquid impregnation method to obtain more accurate results.
