测量标准不确定度的精度评定及应用

Evaluation of Measurement Uncertainty Accuracy and its Application

测量不确定度的A类评定精度受测量次数多少的影响，并由二次标准差来评定。因此，对于高精度测量，测量不确定度精度的影响不能忽视，本文对此进行了论述。

This paper discusses the accuracy of the type A standard uncertainty which is influencedby the times of repeated measurement and evaluated by its standard deviation. So its influence couldn'tbe neglected for high accuracy.
