摘要：As indicated in Sections 48 and 76 of Courant and Friedrichs's book [Supersonic Flow and Shock Waves, Interscience, New York, 1948], if a piston is moved into the gas-filled tube, then a simple compression or condensation wave originates at the piston. And a discontinuity may arise in a compression wave. The wave form may gradually steepen so much that an infinite slope occurs at some point, and at this point a shock will develop. In this talk, we will focus on the development of shock wave which formed due to the impetus of the piston.
