摘要(Abstract)：

为进一步地揭示CO_2相变膨胀的热力学机理，通过CO_2爆燃冲压实验，对起爆温度、CO_2与CO_2聚能剂(一种高能复合材料)质量比对CO_2爆燃冲压过程、CO_2聚能混相流体燃烧速率、燃烧热和峰值压强的影响规律进行了研究。最终得到了不同工况下实验组的压强时程。结果表明：爆燃筒内反应能否发生对CO_2密度和起爆温度有一定的要求；在实验研究范围内，CO_2密度、CO_2与CO_2聚能剂质量比、起始温度与爆燃实验的化学反应速率、压强增长速率呈正相关。
In order to further reveal the thermodynamic mechanism of CO_2 phase change expansion, through the CO_2 deflagration stamping experiment, the effects of detonation temperature and mass ratio of CO_2 to CO_2-EA(a kind of high-energy composite material) on the CO_2 deflagration stamping process, combustion rate, combustion heat and peak pressure of CO_2 energy-forming miscible fluid were studied. Finally, the pressure-time histories of the experimental group under different working conditions are obtained. The results show that whether the reaction in the deflagration cylinder can take place has certain requirements on the density of CO_2 and the detonation temperature. Within the scope of the experimental study, the CO_2 density, the mass ratio of CO_2 to CO_2-EA, and the initial temperature were positively correlated with the chemical reaction rate and the pressure growth rate of the deflagration experiment.
