摘　　要：本文较详细地研究了模型推进剂(AP/wax,AP/A1/wax,AP/RDX/A1/wax)由燃烧转爆轰(DDT)的过程。分析了装药密度和铝粉含量对装药DDT的影响。结果表明:模型推进剂当其配比接近零氧平衡时较易产生DDT;含与不含铝粉的AP/粘合剂系复合推进剂药柱以及硝胺含量为20％的AP/硝胺炸药/A1粘合剂系复合推进剂药柱都不可能产生DDT。In this paper, the deflagration to detonation transition (DDT) processes of AP/ wax, AP/Al/wax and AP/RDX/Al/wax model propellants have been studied in detail and the effects of charge density and aluminium content on the DDT of propellants have been analysed. The results showed that the DDT of model propellants which the oxygen balance values of them are near to zero can easily take place and that the DDT in charges of AP/binder composite propellants, containing and uncontaining aluminium, and AP/nitramine explosive/Al/binder composite propellants, containing 20% explosive, can not occur.
