【摘要】 本文运用分子流体微扰变分理论和碳的物态方程,计算"铝基板/液态CO/蓝宝石"组合靶条件下CO依次经历第一、二、及三次冲击压缩的热力学状态参量。在考虑CO发生分解反应时,产物中碳的性质分别采用固态金刚石、固态石墨及液态碳三种不同情况描述。理论计算结果与实验数据对比发现,二者之间存在明显偏差。因此本文认为,在多次冲击实验中碳产物的状态可能与现有三相碳物态方程存在较大差异,而如何描述CO的化学和物理变化过程还需要更深入研究。更多还原

【Abstract】 Based on the molecular fluid-perturbation variational theory and EOS of carbon, EOS of liquid CO are calculated when it is in turn shocked to 1^st,2^nd,and 3^th multi-Hugoniot states by sandwiched between aluminium and sapphire. When the shock-induced disociation reaction is considered, the carbon in the products is replaced respectively by solid diamond, solid graphite, and liquid state. The calculation results are compared with experimental data, and it is found that an apparent discrepancy exists. So, the properties of shock-induced carbon is very diffenrent from that of three-phase model, and further study is needed to describe the physical and chemical change under shock.更多还原
