电子式三相电能表示值误差测量不确定度评定

Value Error of Electronic Three-Phase Energy Meter Measure Uncertainty Evaluation

本文用一个实例阐述了测量不确定度的评定方法和过程。测量不确定度是误差理论的完善和发展,其分析的主体仍然是误差。从它们的定义可以看出,测量不确定度比误差更具有说明测量质量好坏的能力,测量不确定度比误差更全面更具体。

The paper explained the measurement uncertain evaluation method and course of degree with an instance. The uncertain degree of measurement was perfection and developing of error theory, the subject of its analysis remains the error. Can be found out from their definition, uncertain degree stated the ability to measure quality even more than the error in measurement, the uncertain degree of measurement is more overall and more concrete than the error.
