卷烟含末率的测量不确定度评定

为探讨烟草质检过程中测量不确定度的评定方法,提高实验室检测数据的可靠性,对卷烟含末率检测过程中的不确定度进行了综合分析,找出了卷烟含末率测量不确定度的主要来源,演示了各分量不确定度、合成不确定度及扩展不确定度的计算和评定过程。结果表明,加强仪器设备的日常维护和严格按相关标准要求及操作规程进行检测是控制不确定度的有效手段。

Assessment of Uncertainty in Measurement of Dust Content in Cigarette

In order to examine the method for assessment of uncertainty of measurements in tobacco quality inspection and improve the reliability of test data,the uncertainty in measurement of dust content in cigarette was comprehensively analyzed.The major sources of uncertainty in dust content measurement were found out,and the process of uncertainty calculation and assessment of each component,of synthesis and of expansion was demonstrated.It was concluded that careful routine maintenance of instrument and equipment and strictly observing relevant standards and operating rules were effective means of uncertainty control.
