摘　　要：利用总挥发碱连续流动分析仪的二次进样通道检测了5个卷烟纸样品,考察了方法的准确度、精密度和稳定性,并和国家标准方法的检测结果进行了比较。结果表明:①该方法的回收率范围为99.7%～100.0%,连续5次测定结果的变异系数范围为:0～0.32%,批间变异系数范围为:0～0.34%;②该方法与国家标准方法检测结果的差值最大为0.1%。Five cigarette paper samples were tested with the secondary sampling channel in total volatile bases autoanalyzer, the accuracy, precision and stability of the method were investigated, and the test results were compared with the results by national standard method. The results showed that： 1 ） the recoveries were from 99.7% to 100.0% , the variation coefficients of five consecutive tests ranged from 0 to 0.32% , and the variation coefficients between different batches were 0 to 0.34% ; 2） the maximum difference between the results of this method and national standard method was 0.1%.
