摘要: 利用二级轻气炮加载技术研究了碳水混合物的冲击压缩特性。研究发现：冲击压力p低于19.0 GPa时，石墨与水混合物冲击压缩特性明显不同于金刚石与水混合物的冲击压缩；p大于23.0 GPa后，它们的特性十分接近，这说明有较多的石墨转变为金刚石；当p为52.9 GPa时石墨与水混合物的冲击压缩特性出现明显偏离，这和高压下碳水混合物产生气体成份有关。

Abstract: Behavior of shock compression of the mixture of carbon and water are studied by means of two stage light gas gun. It is found that the behavior of the mixture of graphite and water are different from that of the mixture of diamond and water below shock pressure of 19 GPa; when shock pressure is higher than 23 GPa, their Hugoniots comes closer. It shows that most of graphite has transited to diamond. The Hugoniot of the graphite and water mixture at 52.9 GPa behaviors different from that mention above due to the formation of gas products under higher pressures.
