摘要
简要地介绍了国际计量局（BIPM）组织国际关键比对与“国家计量标准和国家计量院签发的校准证书的相互承认”协议（MRA）的相互关系，给出了中国计量科学研究院参加BIPM组织的正多面棱体CCL—K3关键比对的测量方法、不确定度参量及比对结果。
The relation between key comparisons introduced briefly, which was organized by the Bureau International des Poids et Mesures （BIPM） with Mutual Recognition Arrangement （MRA） for national measurement standards and for calibration and measurement cerificates which issued by NIMs. The NIM （China） participated the regular polyhedron CCL - K3 key comparison. The measuement methods, evaluation of measurement uncertainty parameter and measurement results of regular polyhedron in this key comparison am given.
