摘　　要：目的:为研究检测样本量、检测环境、样本尺寸大小对烟草制品水活度检测结果的影响。方法:用美国Aqualab水活度检测仪,分别选用1/3、1/2、2/3检测样本量,对试验样品进行多次检测。结果:在95%的置信水平下,烟草制品检测样本量在1/3~2/3样品杯容量(15 mL)范围内,对水活度检测结果无显著性影响;在95%的置信水平下,检测环境对水活度检测结果影响显著,因此,制样环节时间应尽可能短;在95%的置信水平下,商标纸不同尺寸大小对水活度检测结果有显著性差异,考虑到检测结果的重复性和稳定性,商标纸尺寸大小宜选择1.0 cm×1.0 cm。Objective:To study the effects of sample size, testing environment and sample size on the test results of water activity of tobacco products. Methods:Aqualab water activity detector was used to detect the sample size of 1/3,1/2 and 2/3 respectively,and the test samples were detected for many times. Results:At the 95% confidence level,the sample size of tobacco products should be in the range of 1/3~2/3 sample cup capacity(15mL),which has no significant effect on the test results of water activity;At the 95%confidence level,the test environment has a significant impact on the test results of water activity. Therefore,the time of sample preparation should be as short as possible;At the 95% confidence level,different sizes of trademark paper have significant differences on the water activity test results. Considering the repeatability and stability of the test results,the size of trademark paper should be 1.0cm×1.0 cm.
