Uncertainty in measurement and its evaluation in analysis and testing Part 5 Some questions which need to claim attention in the evaluation of uncertainty in measurementCAO Hong-yan Technology Centre of Wuhan Iron and Steel Company, Wuhan 430080, ChinaAbstract:Some confused questions which need to claim attention in the evaluation are further discussed, such as the concept of evaluation of uncertainty about A type and B type, the evaluation of combined standard uncertainty, and the influence of temperature on solution volume. The new knowledges, which are raised in the article, are helpful to understand the concept of evaluation of uncertainty in measurement and to make accurate and rational judgments about the problems occurred in the evaluation.[著者文摘]
