近年来,化学计量得到了飞速发展,化学计量中的关键点——用于统一量值的标准物质的研制、生产和使用等也被作为化学计量工作的重点而得到迅速推进。为了适应化学计量工作的蓬勃开展,本刊将通过“化学计量与分析技术”栏目,加强与化学计量相关 In recent years, the rapid development of stoichiometry, the key point in stoichiometry - for the uniform value of the development, production and use of standard substances have also been rapidly moving forward as the focus of stoichiometry. In order to meet the vigorous development of stoichiometry, we will adopt the “” stoichiometry and analytical techniques "column, to strengthen and stoichiometry related
