摘　　要：对A类和B类不确定度评定的概念、合成标准不确定度的评定方法、温度对溶液体积的影响等几个容易混淆和在评定中要注意的问题进一步讨论,提出一些新的认识,有助于对测量不确定度评定概念的理解,并对评定中的具体问题作出正确、合理的判断。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.
