介绍了韩国KRISS,法国LNE,英国NPL,美国NIST以及德国PTB等国家计量机构在微克质量标准方面所开展的研究工作进展,包括微克质量标准的设计,试验方法以及校准不确定度,并给出了未来微克质量标准的研究方向.对于弥补我国的微克质量溯源体系的空白,提高我国质量计量技术水平有着重要的意义. The research progresses on the microgram quality standards of the national metrology institutes such as KRISS in South Korea, LNE in France, NPL in the United Kingdom, NIST in the United States and PTB in Germany are introduced, including the design and test methods of microgram quality standards and the uncertainty of calibration, The research direction of the future microgram quality standard is of great significance for making up for the blank of the microgram traceability system in our country and improving the technical level of our country’s mass measurement.
