250 mL单标线容量瓶容量测量结果的不确定度评定

Evaluation of Uncertainty of Measurement Results of 250mL Single-line Capacity Bottle Capacity

在日常玻璃量器的校准工作中,发现玻璃量器的校准结果受到很多因素的影响。本文主要对250 mL单标线容量瓶容量测量结果的不确定度进行分析,找出校准过程中影响测量值的主要误差来源,对测量方法不确定度进行评定,如实反映测量的置信度和准确性。

In the calibration of daily glass gauges, it was found that the calibration results of the glass gauge were affected by many factors. This paper mainly analyzes the uncertainty of the measurement results of 250mL single-line volumetric flask capacity, finds the main error source that affects the measured value during the calibration process, evaluates the uncertainty of the measurement method, and faithfully reflects the confidence and accuracy of the measurement.
