基于机动车检测中测量结果不确定度评定的研究

Evaluation of Measurement Uncertainty in Motor Vehicle Testing

测量结果的准确性和可靠性在很大程度上取决于测量结果不确定度的大小,因此,合理评定测量结果的不确定度是检测中必须重视的问题。文章分析了机动车检测中测量结果不确定度的影响量,并对测量结果不确定度的评定方法进行了研究,得出了合成不确定度和扩展不确定度结果。

Accuracy and reliability of measurement results depends on the size of the uncertainty of measurement results, to a large extent. Therefore, reasonable evaluation of uncertainty in measurement is an issue that we must pay attention to. The article analyzes the influencing quantity of uncertainty of measurement results in motor vehicle testing, and studies the evaluation method and gets respectively the results of uncertainty synthesis and extension.
