摘　　要：通过优化甲基肼(MMH)和偏二甲基肼(UDMH)的水含量气相色谱分析方法,实现对研制的MMH和UDMH水含量标准物质标称值的测定。为提高定值准确度,同时采用气相色谱标准加入法和液体水分标准物质校正法对影响水含量定值结果的因素进行研究。结果表明:气相色谱标准加入法的标准曲线线性关系良好,相关系数R2均大于0.999;2种方法定值结果偏差较小,F检验和T检验表明2种定值方法测定结果无显著差异。该标准物质对MMH和UDMH水含量的量值传递和量值溯源具有重要意义。By optimizing the gas chromatographic analysis method for water content of methylhydrazine(MMH)and unsymmetrical dimethylhydrazine(UDMH),the determination of the nominal values of the water content reference materials of the prepared MMH and UDMH was achieved.Meanwhile,in order to improve the accuracy of the determination,the factors affecting the determination results were investigated by using the gas chromatographic standard addition method and the liquid water reference material correction method.The results show that the standard curves of the gas chromatographic standard addition method exhibit good linearity,the correlation coefficient R2 is all greater than 0.999;the deviations of determination results of two methods are small,the F test and T test show that the determination results of two determination methods have no significant difference.The reference material possesses great significance for the magnitude transfer and magnitude traceability of the water content of MMH and UDMH.
