中文摘要：

：为研究醋纤滤棒丝束单耗与各影响因素之间的关系，预测和核定二醋酸纤维素丝束消耗，从丝束、滤棒等的特征参数与丝束单耗的内在联系探寻二者之间的变动规律。通过采集近两年我国主要烟用滤棒生产企业的丝束规格（单丝线密度、丝束线密度）、消耗、滤棒规格（长度、圆周）和压降等数据，采用数理统计方法．借助SPSS软件对醋纤丝束单耗进行了实证数理分析，在此基础上建立了醋纤丝束单耗与上述5因素关联的数学模型。模型分析表明，所建立的醋酸纤维滤棒丝束单耗模型具有理论合理性；工业验证结果表明，该模型预测的丝束单耗与实际消耗相符。

英文摘要：

In order to study the relationship between unit consumption of cellulose acetate tow and each affecting factor, predict and assess tow consumption, the relations between unit tow consumption and characteristic parameters of cellulose acetate tow and filter rod were analyzed. By collecting data of tow item （denier per filament and total denier） , tow consumption, filter rod （length, circumference and pressure drop） from main domestic filter rod manufacturers in recent two years, statistics analysis was carried out with SPSS soft- ware, and the mathematical models for the unit consumption and the targeted factors mentioned above were established. The analyzing results showed that the models were rational in theory. The results of productional verification showed that the unit consumption predicted by the model agreed with practical consumption.
