当两层流体之间的相对流速增加时，分界面成为波浪型。
As the relative velocity between the two layers is increased, waves are formed at the interface.
结果表明：随着相对流速的增大，碳钢的腐蚀随之加剧，并发现存在一个临界相对流速值。
The experimental result shows that the corrosion rate of carbon steel increases with the increasing of flow velocity, and there is a critical flow velocity.
试验结果表明：污水射流扩散和近区内的稀释度主要决定于射流佛劳德数、相对水深和相对流速。
The results indicated that the diffusion and dilution of wastewater jet mainly depended on jet Froude Number, relative depth, and relative velocity.
