| 摘 要： | 介绍利用液氮致冷技术实现低温靶的冷却及样品气体的液化，并通过二级轻气炮对液态气体加载进行平面冲击压缩，实验分别测得10～57 GPa一次冲击压缩下液氮和液态CO的Hugoniot关系数据。这些实验数据结果显示，33 GPa以上比其以下更容易压缩，这种现象本质是氮发生离解相变消耗内能的一种表现形势。液态在20 GPa以下表现为一种稳定的压缩过程，而在其以上则伴随有较为复杂的化学反应现象产生。此外，实验研究还发现，20 GPa以下N2和CO两种分子液体的冲击压缩特性非常相似。

| Abstract: | Dynamic equation-of-state for liquids N2 and CO were measured in the shock pressure range of 10～57 GPa, using a two-stage light-gas gun. The liquids were shocked from initial states near their saturation curves at 77.6 K that their densities are about 0.808 g/cm3 and 0.807 g/cm3 for N2 and CO, respectively. The Hugoniot data of liquid N2 and CO are obtained. These results show that nitrogen has been dissociated in shock pressure above 30 GPa. And, the carbon monoxide has a chemically non-reactive compressive process in shock pressure below 20 GPa, but it has a chemically reactive complicated process in up to pressure 20 GPa. In addition, both liquids N2 and CO have the similar shock compression characteristics below 20 GPa. |
