摘　　要：以四氧化二氮为原料,经预脱水、深度脱水和精馏等处理工艺制备了7种浓度的四氧化二氮微量水标准物质。两家实验室采用核磁共振方法对标准物质中的微量水含量进行定值分析,用方差统计方法对定值结果进行数据处理和不确定度评定。Seven concentrations of certified reference material of nitrogen tetroxide minim water was prepared by pre-dehydration,deep-dehydration and rectify treatment technics,and nitrogen tetroxide was used as the raw material. The content of minim water in nitrogen tetroxide minim water standard material was certificated by HNMR in two laboratories. The analytical data was processed,and the uncertainty was calculated with variance analysis method.
