本文首先分析了闸门的调节过程，然后给出了上游常水位闸门和下游常水位闸门工作的数学模型。

In this paper, the governing process of gates is firstly analysed, and then the mathematical models of the operation of upstream constant level gate and that of downstream one are given.

闸门产生强烈振动的主要原因是闸门侧缝射流和下游紊动水流汇合后在门侧形成了自激振荡系统的结果。

The cause of severe vibration is the formation of a self-excited vibrating system by the joint of the gap jet and turbulent flow downstream the gate.

门后通气设施失效使闸门下游面板上的脉动压强增加约8%。

The fluctuating pressure intensity at the downward side of the gate increased 8% due to the invalid of aeration.
