The result indicates that the theoretical analysis is correct, and no resonance will appear between the fluctuating pressure of water flow and the gate vibration frequency.

结果表明：该闸门理论分析方法基本是正确的；其自振频率不会与水流脉动压力发生共振。

The pulsate pressure in high speed flow water will influence the safety of water construction, and the eigenvalue of the pulsate pressure should be confirmed by hydraulic model testing.

高速水流中的水流脉动对水工建筑物的安全运行存在很大的影响，水流脉动压强的特征值一般需通过水工模型试验确定。

At 8:20 p.m. on the day of the explosion the pressure data suggest there was a constant flow of sea water being pumped into the drill pipe that was displacing the heavier mud system which was the primary pressure control for the well.

Out of that it can then give you a small flow of water at a high pressure.
