文章摘要：高速列车进入隧道产生初始压缩波，该压缩波以当地声速向隧道出口传播并产生脉冲波，脉冲波足够大时，会产生音爆响声。

Abstr: The initial compression wave was caused when a high-speed train enters a tunnel. This wave arrives at the exit portal of the tunnel at local speed of sound and produces a pulse wave.

随着激光的持续辐照,陆续传入靶内的压缩波会形成一个阵面陡峭的激波.

This would produce shock wave owing to splice of compress wave.
