足够强的激波扫过铺有可燃粉尘的界面时，波后形成燃烧的粉尘云边界层。为揭示其内部结构，本文对该现象进行了实验和理论两个方面的研究。理论计算表明燃烧粉云边界层可分为三个区域：诱导区、反应区和扩散区，诱导区的粉尘浓度最高，计算获得的粉尘云轮廓和点火延迟与实验结果基本吻合．
A sufficiently strong shock wave sweeps over the interface with combustible dust and forms a burning dust cloud boundary layer. In order to reveal its internal structure, this article has carried on the experiment and the theory two aspects research to this phenomenon. Theoretical calculations show that the boundary layer of burning powder clouds can be divided into three areas: induction zone, reaction zone and diffusion zone. The dust concentration in the induction zone is the highest. The calculated dust cloud contour and ignition delay basically agree with the experimental results.
