%X 目的：建立纺织品消臭性试验的不确定度分析方法。方法：以检知管法测定醋酸的减少率为例，分析不确定度来源；采用A类或B类方法评定各分量的不确定度；根据测量模型和不确定度传播律，求灵敏系数、相关系数，计算合成不确定度和有效自由度，确定包含因子、计算扩展不确定度。结果：检知管法测定醋酸减少率的扩展不确定度为11%，有效自由度为63。结论：本文可为消臭性检知管法的测量不确定度评估提供参考。<br />
Objective: To establish an uncertainty analysis method for the determination of deodorant property of textile products. Methods: Taking the determination of the reduction rate of the concentration about the acetic acid using by the detector tube method as an example, the uncertainty source was analyzed, the uncertainty factors were evaluated by Type A or Type B, the sensitivity coefficient and the correlation coefficient can be gotten according to the measurement model and the uncertainty propagation law, the combined standard uncertainty and the effective degrees of freedom were calculated, the coverage factor was determined and the expanded uncertainty was reported. Results: The expanded uncertainty of the reduction rate about the acetic acid using the detector tube method is 11%, and the effective degree of freedom is 63. Conclusion: This paper provides reference for the evaluation of the determination of deodorant property by the detector tube method.
