摘　　要：叙述了标准物质的定义和有证标准物质的使用环节。阐述了加强有证标准物质资源的监督对正确地发挥标准物质的作用具有十分重要的意义。给出了环境监测领域中氮中一氧化碳、空气中甲烷气体标准物质质量评估的分析方法和实验条件,对全国该类气体标准物质制备生产厂家的分析评价结果及评价过程中存在的问题进行了讨论。This paper described the definition of standard materials and using process of standard materials which have certificates. It has expatiated that strengthening supervision of certificated standard material sources has great significance for playing the role of standard materials correctly. It has given the quality assessment analytical methods and experimental conditions of gas standard material including carbon monoxide in nitrogen and methane in air in the field of environmental monitoring. It also has given the analytical evaluation results derived from nationwide gas standard material manufacturers, and the problems during the evaluation process have been discussed.
