acoustic需要考虑的variation就很多

materials. I don't know why the coherent excitation of the acoustic phonon
or vibrations could be called a uaser, the analogue of laser. For lasing,
there is spontaneous emission and it is fed into the stimulated emission
mode by light travelling in a resonant cavity. Within this traditional
scenario, the claim is not true. |

A sonic boom or "tunnel boom" can also be caused by high-speed trains in
tunnels (e.g. the Japanese Shinkansen). In order to reduce the sonic boom
effect, a special shape of the train car and a widened opening of the tunnel
entrance is necessary. When a high speed train enters a tunnel, the sonic
boom effect occurs at the tunnel exit. In contrast to the (super)sonic boom
of an aircraft, this "tunnel boom" is caused by a rapid change of subsonic
