摘要
分析和识别了使用电子天平配制标准气体时称量过程不确定度分量的来源,根据数学模型对各分量进行了合成。通过实例分析,对称量过程不确定度的评定进行了量化。
The analysis and recognition of the source of uncertainty of electronic balance weighing process of the preparation of standard gas is discussed in this paper. And the various components are synthesized accolxting to the mathematical mod- el. Uncertainty of the weighing process is quantified depending on a real example.
