| 摘 要： | 对一维反应两相流模型进行了研究，建立了定常致密波计算模型，对推进剂多孔床中不同速度的致密波进行了计算，得到了致密波区内的参数分布，通过分析致密波的结构，发现亚音速致密波从波前到波后所有物理量光滑过度；而超音速致密波波头存在间断。

| Abstract: | Two-phase flow equations are studied and a compaction wave model estab-lished. The model is used to analyze steady compaction waves in a porous bed of high-energy solid propellant.The parameters of compaction zone are obtained from the model. The structure of the compaction wave is also studied. It is shown that there exist a shock preceding the compaction wave for supersonic compaction waves, but no lead-ing shock exists for subsonic compaction waves. |

| Keywords: | compaction wave deflagration-to-detonation transition shock wave |
