烟草专卖管理人员虽然主观上认识到假冒伪劣卷烟产品分布具有地域性,但长期以来却没有准确地得到统计报告.统计分析并直观展现假冒伪劣卷烟数据对于烟草专卖部门的执法办案具有特定的指导意义.本文分析了2016-2018年云南省假冒伪劣卷烟查获情况,制成了分县域的云南省假冒伪劣卷烟查获情况数据地图,为相似领域的执法部门、鉴定机构提供了一种选择案情查办重点的依据,为更加有的放矢地培养执法人员技能提供了参考.

Objective: Established a group of models used to quickly distinguish anti-counterfeit cigarette packaging paper. Methods: The model based on the same color oil on packaging paper from 3 different brands: Yunyan, Yuxi, and Hongtashan. The Fourier Transform infrared spectroscopy （FTIR） spectrum were collected from 116 samples totally by Attenuated Total Reflection （ATR） accessary. 56 spectrum were used to build the models and 20 samples of each brand were used to verification. Spectrum were second derivative processed and spectral ranges were selected as 3 200~2 700, 1 800~1 580, and 801~720 cm-1. Results: Using Mahalanobis distance discriminant method to establish 4 models （3 brands and 1 multiple）, all of the accuracy of models reached to 100%. Conclusion: This is the first time to use the same color oil FTIR spectrum to distinguish real and fake cigarette packaging paper which were highly improve selection efficiency for large number of samples.

Fifteen samples were tested to study stability and correlation of ISO/CD 3550-3、ISO 3550-1 and ISO 3550-2 results. Bootstrap numeric simulation method, correlation analysis and multi-factor analysis of variance were adopted to analyze data. Results showed that stability of the three methods was at the same level, and ISO/CD 3550-3 result showed a significant positive linear correlation with that of <br> ISO 3550-1 and ISO 3550-2, respectively. Different methods can significantly affect testing results.

[Objective]The study aimed to establish the rapid analysis method to determine water in tobacco essence by Karl Fischer method. [Method] After automatic pre-titration and calibration with cassette reagent, the moisture contents in 4 kinds of tobacco essence were titrated by cassette reagent, and the moisture content in environment was titrated in order to eliminate background interference. At the same time, the recovery rate was calculated according to measured quantity before adding standard, adding standard and measured quantity after adding standard. The relative standard deviation was calculated according to the determination results from 6 parallel determinations on tobacco essence. [Result] Analysis results of determining the moisture contents in tobacco essence by using Karl Fischer method were satisfactory, with the relative standard deviation at 1.65%-2.54% and the recovery rate of 93.46%-106.15%. The determination on the moisture contents in tobacco essence by using Karl Fischer method showed that the moisture contents in 4 kinds of tobacco essence had great difference, which was in 1.49%-5.74% and the result was satisfactory. [Conclusion] Using Karl Fischer method to determine water in tobacco essence was sensitive, accurate, well repeatable, and provided a reference for determining water in tobacco essence.
