摘　　要：讨论了改性双基球形小粒药中RDX颗粒的分布和RDX热分解的特点,提出了RDX改性双基球形小粒药的燃烧机理。通过密闭爆发器实验测定了RDX改性双基小粒药的燃烧特性,并对实验结果进行了理论分析。结果表明,改性双基球形小粒药中RDX与双基火药基体的分解是各自独立进行的;随着压力的升高,改性双基小粒药的燃速将大于改型双基小粒药的燃速。The grain distribution and thermal decomposition characteristic of RDX in RDX modified double base spheric small size propellants are discussed. The combustion mechanism of RDX modified double base spheric small size propellants is presented. The combustion properties of the RDX modified small size propellants are determined by a closed vessel and analyzed theoretically. The results show that the decompositions of RDX and double-base groups in modified double base spheric small size propellants are carrying through independently. With the improvement of the pressure, the burning rate of the modified double base spheric small size propellants will be higher than that of remodeled double base spheric small size propellants.
