According to certain research, the spread velocity of sound waves has nothing to do with the speed of the ripples.
研究表明，声波在同一介质中的传播速度和波源的速度无关。
In order to spread this technique, I have made trial VSP modeling during shothole drilling: shallow seismic velocity survey during shothole drilling.
为了应用和推广这一新技术，我们做了随钻VSP模拟试验，即地表浅层炮井随钻地震速度测量。
Based on the idea of neighboring regions velocity spread, an algorithm of water wave transmission and diffusion is proposed.
