摘　　要：计算了在氧化硼与镁物质的量比为1∶1时发生自蔓延反应所需的预热温度。研究和讨论了不同球磨时间对该体系起爆温度、燃烧产物相的影响。对浸出产物进行了X射线衍射分析和元素分析。The preheating temperature required for self-propagating reaction is calculated when the molar ratio of boron oxide to magnesium is 1∶1.The effects of different ball milling time on the detonation temperature and combustion product phase of the system are studied and discussed.X-ray diffraction analysis and elemental analysis are performed on the leached products.

关 键 词：自蔓延 绝热温度 球磨 硼粉
