  • Online:2009-08-20 Published:2009-08-20

摘要: 评价直线拟合质量宜用A类不确定度,拟合线段外推会使不确定度增大.

关键词: 相对压力系数, 直线拟合, 标准偏差

Abstract: The type-A evaluation of measurement uncertainty should be to evaluate the quality of linear fitting results. The uncertainty will increase when the fitting equation is applied outside measuring line segment.

Key words: relative pressure coefficient, linear fitting, standard deviation
