摘　　要：详细介绍了新型两相激波管设计原理、气体与气固两相混合物分界平面的产生方法及粉尘浓度在线测量。作为应用，给出了强激波（Ｍａ＝５．１５）与气固混合物分界平面相互作用的实验现象，讨论了用于测量颗粒群阻力系数的可行性。In this paper,a newly developed two-phase shock tube was presented in detail,in which a planar interface between a gas and a particle gas mixture was generatedand particle concentrations were measured quantitatively and temporally.Initial interactionbetween an incident shock wave with Mach number of Ma = 5.15 and a cornstarch nitrogen mixture was observed.For coming application,the feasibility to measure the drag coef-ficient of particles in a cloud is discussed
