摘要

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特性；p大于23 GPa后，它们的特性十分接近；当p为52.9 GPa时，石墨与水混合物表现出反常的冲击压缩特性，压力增加而体积出现膨胀，这与高压下碳与水发生化学反应产生气体相关。还对碳水混合物的相互作用势及混合法则的选取进行了讨论。

Abstract: The behavior of shock compression of the mixture of carbon and water is studied by means of loading technique of two stage light gas gun. It is found that the behavior in the mixture of graphite and water is different to the mixture of diamond and water below shock loading pressure of 19 GPa; as shock pressure is greater than 23 GPa, their compression Hugoniot is close, it shows that the more graphite has transited to diamond. The shock Hugoniot at 52.9 GPa shock pressure in the mixture of graphite and water is different abnormally, i.e. when the pressure rises, the volume expands, it related to produced gas because the carbon reacts with water under high pressure. The emission spectra above mentioned mixtures are observed by means of OMA spectrometer. The results show that the emission spectra on the obvious head radiation in the range from 350 nm to 750 nm as shock pressure is larger than 16.4 GPa. The spectrum bands of C2, CO, CO2 are obvious, when shock pressure is larger than 34 GPa, it shows that the carbon reacts with water. The choices of interaction potential and mixing law for the mixture of carbon and water are discussed.
