摘要
对使用凯氏定氮仪测定肥料中总氮含量方法进行不确定度评定,分析该测定方法中不确定度的来源,通过数字模型对各不确定度分量进行评定,并给出了结果的报告形式。
The uncertainty of measurement for the determination of nitrogen content in the fertilizer by Kjeldahl apparatus was evaluated in the paper.The determination of the sources of uncertainty for the method was analyzed.Through the digital model of the uncertainty components were assessed,and gives the results of the report form.
