摘　　要：综述了国内外硼颗粒点火和燃烧的研究状况 ;讨论了改善硼颗粒点火和燃烧行为的途径。指出硼表面的氧化物是造成硼点火困难和燃烧效率低的主要因素 ;在含硼推进剂中使用细粒径的硼 ,对硼进行包覆并添加其它组分 。The researches on ignition and combustion of boron were reviewed, and the approach to improve the ignition and combustion performance of boron was discussed. It is shown that the difficult ignitability and low combustion efficiency of boron are caused by oxide of boron surface. Using fine diameter boron, coating boron and adding other ingredient into the boron based fuel rich propellants can increase employed efficiency of boron.
