摘要
对二氧化硫氧化催化剂样品中五氧化二钒含量测定的测量不确定度进行了评定。该方法的扩展不确定度取决于方法标准中重复性限 (r) 。
The measurement uncertainty of determination of V 2 O 5 content in the SO 2 oxidation catalyst sampl is assessed. The expanded uncertainty of the method is determined by the repeatability limit in the standard. It may reduce to lower rank by type A evaluation of standard uncertainty.
