Tsunamis travel as fast as jet aircraft in deep water, where they are spread over a far deeper water column and make for smaller and very gradual waves at the surface.
在深海水域，海啸的传播速度像喷气式飞机一样快，但在海面看到的波浪不大。
Next, the belieal columnar vortex get enough the vorticity supplied by the crosswise spread of the secondary jet flow to rotate stably.
同时，分流射流横向扩展继续为螺旋柱状旋涡提供足够的涡量，使其稳定旋转。
Aimed at the bottleneck problem in the spread and application of the abrasive suspension jet technology from abroad, a new technical equipment of abrasive suspension jet cutting was developed.
