测量不确定度评定中相关性的非相关性转变

当出现输入量估计值相关时 ,不论是线性还是非线性函数关系 ,在合成标准不确定度评定中 ,均可通过数学模型的变化或是分组合成而不去评定相关系数使计算大大地简化。

When correlation arises in estimated value of input quantity,in the assessment of uncertainty of combined standards,the computation of linear or non-linear functional relationship may be greatly simplified by changing the mathematical models or using analytical synthesis instead of assessing the related coefficients.
