摘要
依据不确定度评定准则,采用一种新的方法,即忽略量取样品体积的不确定分量,只考虑样品前后两次恒重的不确定分量,对重量法测定水中悬浮物和全盐量的不确定度来源进行了识别、分析和量化,确定了不确定度分量,据此计算出合成标准不确定度。重量法测定水中悬浮物和全盐量的不确定度评定的方法适用于实验室内部不确定度的评定。
According to the rule of uncertainty evaluation,this article develops a new method to discern and quantify the uncertainty source about gravimetric method in determining the suspended substance and total salt content in water.The dominant uncertainty components were determined so that the synthetic standard uncertainty was calculated.This method is applicable to uncertainty evaluation about gravimetric method in determing the suspended substance and total salt content in water.
