【摘要】 科克伦检验和格拉布斯检验作为标准数据质量保证的重要组成部分，它们在标准中的应用，可以避免因数据问题而导致错误的分析结果，有助于确保精密度实验数据的方差一致性、准确性，并识别和处理异常值，从而提高整个标准验证过程的可靠性和有效性。本文以扣式电池首次放电比容量及首次充放电效率的精密度实验测试数据为例，阐述了应用科克伦检验和格拉布斯检验对精密度实验数据进行处理的方法，以及重复性限和再现性限的计算方法，为标准编制说明中的实验验证方法提供了技术指引和支撑。更多还原

【Abstract】 The Cochran and Grubbs tests are important components of standard data quality assurance. Their application in standards can help avoid incorrect analysis results caused by data problems, ensure consistency and accuracy of the variance of data of precision experiments, and identify and deal with outliers, which will improve the reliability and effectiveness of the entire standard verification process. Taking the data of precision experiment of the initial discharge capacity and initial charge as well as the discharge efficiency of button batteries as examples, this paper describes the method of processing precision test data using Cochran’s test and Grubbs’ test, as well as the calculation method of repeatability limit and reproducibility limit, which provides technical guidance and support for experimental verification methods in the development instruction of standards.更多还原
