大米水分测量结果不确定度的评定

THE ASSESSMENT OF THE UNCERTAINTY IN MEASUREMEN OF RICE MOISTURE CONTENT

对大米水分的测量结果标准不确定度、扩展不确定度及不确定度表述进行了系统的分析和评定,并编写了相应的计算程序,对测量结果不确定度评定中的建模、分量计算、合成标准不确定度、扩展不确定度的评定和计算方面作了有益的尝试。描述了影响大米水分测定结果各分量对其不确定度的相对贡献。

This paper analyzed and assessed for the uncertainty in measurement result,branch and description of the for the rice moisture, and also compiled relevant calculating procedure, The reseach made some beneficial attempt in the modeling and component calculating , the assessment and calculating of synthesis standard uncertainty and expansion uncertainty. The paper also described the comparative contribution of each component to the uncertainty in measurement of rice moisture content. The uncertainty in measurement, which is based on error theory ,is a parameter for describing the dispersibility of measured components. With the development of the society and the improvement of living standard, the nutrition and safety of food are attached great importance. So that we gave a objective evaluation, for measuring rice moisture content.
