There is no cavitationdamage and irrigation water and so on.
不存在汽蚀破坏及灌引水等问题。

The calculations are also useful to estimate the maximum velocity of overflow surface that can be use to judge the possibilities of cavitationdamage at the stepped overflow surface.
同时,该式亦可用于对台阶溢流坝坝面最大流速进行估计,以便判别坝面出现空蚀破坏的可能性。

Pressure fluctuations with high or low frequency can lead to acute cavitationdamage in draft tubes or vibration of the vane of turbine.
