摘　　要：为了评估温压炸药的能量释放效率,通过理论计算和试验测试,得到塑料黏结炸药(PBX)及温压炸药的单位质量耗氧量、绝对耗氧量和爆炸罐中炸药的最佳弥散浓度,依据实验数据评估了炸药的能量释放效率。结果表明,温压炸药的弥散浓度在0.84g/L时爆炸耗氧量最大,其单位质量试验耗氧量是PBX的1.55倍,能量释放效率是PBX的1.13倍。To evaluate the energy releasing efficiency of thermo-baric explosives, the oxygen demand per unit mass, absolute oxygen demand and optimum dispersion concentration in exploder of thermo-baric explosive and plastic bonded explosive （PBX） were obtained by combining theoritical calculation and experimental test. The energy releasing efficiency was evaluated according to experimental data. Results show that oxygen demand of the thermo- baric explosive is the biggest when its dispersion concentration is 0.84 g/L. The experimental oxygen demand per u- nit mass of the thermo-baric explosive is 1.55 times higher than that of PBX, and its energy releasing efficiency is 1. 13 times higher than that of PBX.
