| 摘 要： | 实验中利用带示踪粒子的X光脉冲摄影和阴影摄影技术，成功拍摄了激波与堆积粉尘作用后粉尘内部的波系图像和波后卷扬粉尘云的形状，进而测得入射激波倾斜角、透射激波倾斜角和波后物质界面折射角。在此基础上，利用相关理论对该流场进行分析，确定出该堆积粉尘状态方程中中的待定系数。计算结果与测试结果符合较好。

| Abstract: | The flow fields both in gas and dusty bulk and the entrained dust cloud induced by interactions of shock waves and a surface of dusty bulk were record,by means of shadow graphs and pulsed X ray shadow graphs with trace particles.Incident shock angles,transmitted shock angles and turning angles of material surface can be measured from the graphs.Based on experiments and shock polar analysis,the constitutive equations of granular material were determined and calculations were performed.The measured and calculated results were in good agreement. |
