    摘要: A free piston shock tube/tunnel having a mechanism for increasing the holding time, without correspondingly increasing viscous losses in which the shock tube/tunnel includes a diaphragm positioned in the area of connection between the compression tube and the shock tube and a selectively replaceable orifice insert positioned near the diaphragm in which the orifice insert has an opening with a diameter less than the internal diameter of the shock tube.
