| 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: | In this paper, the author described the cause to generate time resolution, the importance of the time resolution measurement in high speed photograph, the work done, and the difficulties encountered. A new method to determine the time resolution is introduced and results are presented, which shows that the time resolution for GSJ camera reaches as high as 8 6ns with a RMS error of 1ns. |
