自从本世纪初美国第一个钢铁成分分析标准物质问世以来,标准物质的研制和应用得到迅速的发展,应用范围不断扩大。从地质、冶金发展到化工、机械、食品、医药、生物、环境、农业等,几乎涉及到国民经济、科学技术各个领域。 目前我国已研制出各种类型的标准物质上千余种,其中有一级标准物质500多种。这些标准物质广泛应用于各种测量的质量保证,生产过程中的质量控制与产品质量检验,测量方法与测量仪器的评价与校准,合作实验室的质量 Since the advent of the first standard component analysis of steel in the United States at the beginning of this century, the development and application of standard materials have been rapidly developed and their applications have been expanding. From geology and metallurgy to chemical industry, machinery, food, medicine, biology, environment and agriculture, it involves almost all fields of national economy, science and technology. At present, China has developed more than a thousand kinds of reference materials of various types, of which there are over 500 kinds of standard substances. These standards are widely used in various measurement quality assurance, production process quality control and product quality inspection, measurement methods and measurement equipment evaluation and calibration, the quality of the cooperation laboratory
