摘　　要：通过对AP和硼及其混合物进行热分析实验,研究了硼在AP分解过程中参与反应的程度;用氧弹式量热计测试含硼富燃料推进剂的爆热,分析硼在推进剂燃烧过程中的放热。结果表明,对各组分含量相同的含硼富燃料推进剂用AP包覆硼粒子和提高超细AP含量可促使硼在AP分解过程中参与反应,使AP/B(1∶1)热分解的放热量增加,提高推进剂的爆热,有利于推进剂中硼的燃烧。The degree of boron participation in reaction in the course of pyrolysis of AP was investigated by means of thermal analysis of AP and boron and their admixture. The heat release of boron during the combustion of propellant was analyzed by measuring the explosion heat of propellant. The results show that coating boron with AP and increasing the proportion of superfine AP can promote the degree of boron participation in reaction, enhance the capacity of releasing heat in the course of the pyrolysis of AP/B, increase the explosion heat of the propellant, and therefore is beneficial to boron combustion in propellant.
