叙述了化学计量的特点、作用和重要性及其研究内容,探讨了标准物质量值传递系统及实现标准物质量值溯源性的途径,阐述了建立化学测量溯源性的重要性、困难性、复杂性及基本设想和途径,并对化学计量中物质的量“摩尔”进行了简要论述。
The characteristics, functions and importance of stoichiometry and the contents of its research are described. The system of measuring the mass of the standard substance and the way of tracing the traceability of the standard substance are discussed. The importance, difficulty and complexity of setting up the traceability of chemical measurement are discussed Nature and basic ideas and ways, and the stoichiometry of the amount of material “Moore” were briefly discussed.
