摘　　要：[目的]分析评定小麦水分含量的测量不确定度。[方法]分析了测定小麦水分含量测量不确定度的来源,采用GB 5009.3-2010标准方法测定小麦水分含量,并对测量不确定度的影响因素进行分析。[结果]通过分析评定测定结果的不确定度,得出小麦水分含量测定结果扩展不确定度为0.03%。[结论]在小麦水分含量测量不确定度评定时,重复测量小麦水分含量是影响其测量不确定度的主要因素。[ Objective] To analyze and determine uncertainty degree in measurement of moisture content in wheat. [ Method] The sources of the measurement uncertainty of the moisture content in wheat were analyzed, GB 5009.3 -2010 was adopted to determine the moisture content, and the influencing factors on uncertainty measurement were analyzed. [ Result ] The expanded measurement uncertainty of wheat moisture content calculated from determination was 0.03%. [ Conclusion] Measurement repeatability is the main factor influencing the wheat moisture measure- ment uncertainty.
