采用近距摄影、扫描电镜、电子探针、X射线衍射、能谱、差热分析、傅里叶红外及变温原位红外分析等多种技术，对以铅、钢化合物和炭黑为催化剂的双基推进刑催化燃烧过程进行实验研究。结果表明，铅盐分解所得的PbO是催化核心物质，而炭黑和锅盐所起的助催化作用在平台区更为明显。 A variety of techniques such as near-field photography, scanning electron microscopy, electron probe, X-ray diffraction, energy dispersive spectroscopy, differential thermal analysis, Fourier transform infrared spectroscopy and infrared in situ variable- Experimental Study on Catalytic Combustion Process of Double Base Propellant. The results show that the PbO obtained from lead salt decomposition is the core material of catalysis, and the co-catalytic effect of carbon black and pot salt is more obvious in the platform area.
