中文摘要:

      正确地选择和使用能力验证结果统计方法对于能力验证的成功实施具有至关重要的作用。本文对国内外化学检测领域能力验证的参考指南进行检索, 重点分析各指南或标准在指定值、能力评定标准差、能力统计量、图示法等能力验证结果统计关键环节的异同点。通过分析发现, 不同的认证认可组织对于能力验证结果的统计方法及能力评定既相似又有各自的特点, 这些组织制定的能力验证结果统计及能力评定准则大多以ISO/IEC17043、ISO 13528为基本依据进行编制, 但又不完全相同, 有不同程度的细化、扩展和限制。本文提供的检索资源及提炼的观点可以为我所以能力验证提供者身份首次组织实施能力验证提供理论参考, 为能力验证统计人员正确选择和使用统计方法提供更多的信息和借鉴。

英文摘要:

      It is very important for the successful implementation of proficiency testing program to select and apply the statistical methods correctly. The domestic and overseas reference protocols for proficiency testing of analytical chemistry were searched, and the critical statistical techniques of each protocol or standard, such as the assigned value, the standard deviation for proficiency assessment, performance statistics and graphical methods were analyzed. It is found that different organizations had similarities as well as characteristics in statistical techniques. The proficiency testing statistical standards or protocols made by these organizations were mostly based on ISO/IEC17043, ISO 13528, but were not the same with varing elaboration, expansion or limitation. The retrieval resources and essential points of the study can provide theory references for organizing proficiency testing program as proficiency testing provider for the first time, and provide proficiency testing statistician more valuable information on the right selection and employment of statistical techniques.
