同时水流流速减小，阻力系数增大，这说明水流克服阻力做功所消耗的能量也增加。
It shows that consumed energy for working of water flow against resistance tends to increase.
结果表明：此种消能工能改善台阶式溢洪道的水流流态，大幅度地减小水流流速。
The results indicate that this kind of energy dissipation function can improve the water flow regime in the stepped spillways and reduce the flow velocity by a wide margin.
鱼骨坝束窄了河道过水断面，引起坝体两侧水流流速的增大，坝田内流速则大幅度减小；
Alongside the dike, the flow velocity gets larger, and it is on the contrary in the dike field.
