| 摘 要： | 在新建立的激波管中实现了激波对沉积可燃粉尘的卷扬与点火。利用自行设计的瞬态阴影摄影系统和高空间分辨率的新型红外光敏二极管成功拍摄了激波后燃烧粉尘云的阴影图像和测量了激波后可燃粉尘的点火诱导时间。通过对实验结果的较深入的分析，揭示了激波与可燃粉尘床相互作用的基本特征

| Abstract: | By means of transient shadowgraphy with a Fresnel lens and a newly developed ultrared photodiode,the shadow photograph and the ignition time of combusting dust clouds induced by a shock sweeping a dust layer were recorded successfully and presented in this paper .The results of experiments and analysis revealed the basic characteristics of interactions between shock waves and the combustible dust layer. |

| Keywords: | shock ignition combustible dust layer shadowgraphy. |
