采用热重-质谱（TG-MS）联用技术研究了NiO纳米粒子对硝酸纤维素（NC）/三甘醇二硝酸酯（TEGDN）组成的双基推进剂热分解的催化作用。结果表明，在TEGDN/NC推进剂中加入2%的NiO纳米粒子，在188°C左右热分解加速，热重-质谱分析表明NiO纳米粒子的加入导致了推进剂强度的提高在热分解过程中，m/z=27、28和29的MS信号的强度（峰面积）降低，但m/z=18、30、44和46（峰2）的MS信号的强度降低。并对催化机理进行了探讨。
The catalytic effect of NiO nanoparticles on the thermal decomposition of double-base propellant composed of nitrocellulose (NC) and triethylene glycol dinitrate (TEGDN) has been investigated by thermogravimetry–mass spectrometry (TG–MS) coupling technique. It was shown that adding 2% of NiO nanoparticles to TEGDN/NC propellant can accelerate the thermal decomposition process after around 188°C TG–MS analysis indicated that NiO nanoparticles have resulted in the increase in intensity (peak area) of m/z=27, 28, and 29 MS signals, but the decrease in the intensity of m/z=18, 30, 44 and 46 (peak 2) MS signals during the thermal decompsition. The catalytic mechanism was also discussed in this paper.
