摘　　要：采用1HNMR、13CNMR方法确定了某新型液体推进剂的组分为:有机含能氧化剂、安定剂和钝感剂,并采用气相色谱与红外联用法进行了验证;根据各化合物的核载量,采用参比物反丁烯二酸对其中组分进行定量分析,精密度结果与高效液相色谱测试结果相当。NMR法定量分析的试验相对标准偏差和平均回收率分别为:有机含能氧化剂0.21%,99.9%;安定剂0.32%,99.9%;钝感剂0.11%,99.7%。Structures of organic components in a new liquid propellant were identified by the nuclear magnetic resonance spectroscopy （NMR）, and validated by the combination of chromatogram and IR （GC/IR）. The components of the propellant were confirmed, including organic energetic oxydant, stabilizer and phlegmatizer. The content of every component was quantified by the reference material trans-butenedioic acid, according to the nucleus-carrying mass （NCM） of every component. The result of precision test with NMR is consistent with that with high performance liquid chromatography （HPLC）. The relative standard deviation（RSD） obtained is 0.21% for organic energetic oxidant, 0.32% for stabilizing agent, and 0. 11% for phlegmatizer, respectively. Results of recovery test are 99.9% , 99.9% , and 99.7% respectively.
