物理实验的不确定度评定

UNCERTAINTY EVALUATION IN PHYSICAL EXPERIMENTXue Yuncai

针对不确定度在物理实验的数据处理中存在的不规范问题，简明系统地引入不确定度的概念、评定和修约．通过表征合理地赋于被测量值以分散性，评定实验的测量误差和评价实验质量，从而实现了不确定度的评定．它有助于物理实验课程与现代工程技术和计量技术接轨，且对不确定度在物理实验课程中的应用有指导作用．

As the falling short of specification about uncertainty are existed in data treatment of physical experiment,the concept,the evaluation and the amendment about uncertainty are explained concisely and systematically.The uncertainty can be used to evaluate the errors and the quality of experiment by expressing the dispersion of the measurement.So the application in physical experiment course can be directed by uncertainty.
