摘要
以蒙特卡罗法为基础,结合Minitab分析软件对盐溶液密度的测量不确定度进行评估。蒙特卡罗法除在测量模型是非线性、计算公式的偏导数求证困难或不方便等情况下评估测量不确定度有明显优势外,其在单一测量数据的不确定度评估中也有便利性,可以方便求出标准不确定度,并给出指定置信概率下的扩展不确定度。
Based on Monte Carlo method and Minitab analysis software, the measurement uncertainty of salt solution density is evaluated. Besides obvious advantages in situations of the nonlinear measurement model and dififcult or inconvenient partial derivation of the calculation model, Monte Carlo method has also advantages in the uncertainty evaluation of a single measurement data. It is very convenient to determine the standard uncertainty and give the expanded uncertainty of conifdence probability.
