They regulate the flow of water by the sluicegate.
他们用水闸门控制水的流量。

The secondary parts such as radial sluicegate and its stand were neglected, the number of elements were decreased and the abnormal stress caused by improper loading were avoided in this method.
有限元模型减去了弧形闸门、闸门支架等非主要部件，使模型规模减小，避免了因荷载不恰当引起的应力异常。

The underflow energy dissipation is a commonly used type for sluicegate, and the apron is an important component of energy dissipation structure.
