摘　　要：介绍了最小二乘法评价直流增益和直流偏移两项指标以及不确定度分析和评价过程，同时给出了一个分析评价实例。该过程及结论可应用在对于测量标准进行相应指标的不确定度分析上，也可用于估计指标本身的不确定度。In this paper,the evaluation course of DC gain and offset of linear measurement system using the least square method is described,the uncertainty analysis of the evaluation is discussed,and in the meantime an example of evaluation and analysis is introduced in detail. The course and results can be used in the uncertainty analysis of some measurement standard or the uncertainty ana1ysis of gain and offset themselves.
