The full wave model phase analysis can be used to study the first motion directionofwaves.
全波模型震相分析法可用来研究震相的初动方向。

When two wavesof opposite direction but similar frequency collide, they create a special kind of pressure wave that carries energy to the ocean bottom.
当两方向相反但频率相似的波浪相撞时,会产生一种特殊类型的压力波,而这种压力波会把能量输送到海底。

Transmitters emit wavesof a certain frequency in the direction of the target.
