| 摘 要： | 通过对冲击引起石墨转变为金刚石两种相转变模型的比较和冲击波在疏松介质中传播特性的分析，研究了在冲击波阵面内形成热斑的机制和引起原子发生异常迁移的机制，进而探讨了在冲击波阵面内，在热斑区，石墨→金刚石的相变过程，以及卸载时金刚石的石墨化过程。

| Abstract: | By comparison of two models of phase transition for graphite to diamond and the analysis of shock wave behaviour in porous materials,the formation mechanism of hot spot and the anonalous (atoms) transfor mechanism have been discussed.Also,the transition process of graphite to diamond at hot spots region in shock wave front and the regraphitization process upon unloading have been (analyzied). |

| Keywords: | diamond shock phase transition hot spot |
