合金材料是制造业的基础之一,质量分析是其重要保障,也是国际贸易中一个重要的组成部分。产品质量的检测依赖各国的化学计量溯源体系,为协调彼此间的测量活动,需要通过国际比对等加以实现。此外,化学分析多采用相对分析方法,不同于物理测量,也需要通过国际比对对各国的测量能力和测量过程出现的问题进行研究。根据国际计量局资料,合金材
Alloy material is one of the foundations of manufacturing. Quality analysis is an important guarantee and an important part of international trade. Product quality testing relies on the country’s stoichiometric traceability system, in order to coordinate the measurement of each other’s activities need to be achieved through international comparison and so on. In addition, the chemical analysis mostly adopts the relative analysis method, which is different from the physical measurement. It is also necessary to study the measurement ability of each country and the problems arising in the measurement process through international comparison. According to the International Bureau of Metrology information, alloy materials
