引入不确定度的基础化学实验数据处理方法探讨

根据当前不确定度的应用现状,讨论了基础化学实验中计算不确定度的必要性和可行性。建议在学习基本误差理论的基础上找出误差的主要来源,在真值已知时直接计算误差,在真值未知时确定主要不确定度分量。计算不确定度时只考虑1~2个主要不确定度分量、忽略次要不确定度分量。上述实验数据处理方法可以满足基础化学实验的要求。

Study on Data Processing in Fundamental Chemistry Experiment with Introducing Uncertainty

Necessity and feasibility of uncertainty calculations in fundamental chemistry experiment were discussed depending on the current situation of uncertainty application. It was recommended that main sources of error be identified according to the basis of learning error theory, and error be calculated directly when true value was know, and the main components of uncertainty be determined when the true value was unknown. Uncertainty was calculated by considering 1-2 main components of uncertainty and ignoring minor components of uncertainty. The method for uncertainty calculation described above meet the requirements of fundamental chemistry experiment.
