摘　　要：为定量描述烟气成分在烟支内传输的截留过程,从烟气成分的截留机制出发,基于不同的截留过程假设,推导出了3种描述烟支截留的近似数学模型。结果表明:(1)3种模型的截留率具有共同的双指数表达形式,且可以统一为一个通用表达式;(2)双指数形式的模型表达式可以较好地拟合卷烟烟丝段、滤嘴对烟气成分的截留数据;(3)根据截留率的通用表达式可推导出滤嘴选择性过滤的模型参数条件以及选择性过滤系数与模型参数之间的定量关系;(4)截留率的通用表达式可以解释滤嘴不同段截留效率的差异。In order to quantitatively describe the retention of smoke components by residual tobacco rod during smoking,three approximate mathematical models for the filtration process were derived from different hypotheses of the retention process based on the filtration mechanism.The results showed that:1)The expression of retention in the three mathematical models had a common double exponential form and could be unified into a general expression.2)The double exponential expression could fit the retention data of smoke components by the tobacco rod and the filter satisfactorily.3)According to the general expression,the model parameter conditions for selective filtration by the filter and the quantitative relationship between the selective retention coefficient and the model parameters could be derived.4)The general retention rate expression could be used to explain the difference in retention efficiency by different sections of the same filter.
