| 摘 要： | 采用单曝光光栅干涉或双曝光光栅干涉，研究激波过弯道绕双圆柱传播的微波流场。采用单曝光法，成功显示入射激波到第一圆柱上的反射、绕射，到达第二圆柱上的反射、绕射。在同一底片上采用双次曝光，第一次脉冲记录直道上的平面波，第二次脉冲记录激渡过弯道绕双圆柱流场。这些照片对于研究反射、绕射及它们边界的相互作用是很有用的。

| Abstract: | By single-exposed grating interference or double-exposed,flow field of shock wave propagation through curved channel around doublecylinder is investigated in this paper .By single pulse exposure, we cansuccessively visualizes reflection of incident shock wave at first cylinder,diffraction through oyer first cylinder,reflection and diffraction at secondcylinder.To make double pulse exposure at the same film,first pulse recorded plane wave at straightway, second pulse recorded flow field of shockwave propagation through curved channel around double cylinders.Thesephotos are useful to the research of reflection,diffraction and their actionsat boundary. |
