WebThe shock wave of a coal and gas outburst is a high-pressure and high-speed impact airflow formed rapidly after the outburst. The propagation destroys the ventilation facilities and causes the destruction of the ventilation system. The theoretical research on the outburst shock wave is of great significance. In order to deeply understand the formation … WebEssentially, a wave packet can be pictured as a single sea wave, while a periodic wave is like a never-ending set of regularly-produced sea waves. Both move and evolve. With this in mind, we now define the concept of stationary waves, which are waves formed by the superposition of two periodic waves with the same frequency travelling in opposite …
