| 摘 要： | 介绍了硼的物理化学特性和燃烧机理，硼的点火延迟期长、燃烧效率低是由其本身的特性所决定的。改善硼的点火及燃烧特性可以通过控制其粒度，表面包覆、添加低燃点金属等途径来实现。采用ＧＡＰ包覆硼粒吃可以显著降低硼粒子的点火时间，提高了燃烧效率。

| Abstract: | Physicochemical properties and combustion mechanism of boron are introduced.Long ignition delay time and low combustion efficiency are due to the properties of boron itself.Particle size,surface coat and adding low melt metal (Mg,Al or Zr) can improve the ignition and combustion characteristics of boron particles. Test shows that the ignition delay time shortens effectively and the combustion effciency increases as B particles are coated with GAP. |
