If it did, the pressure of the oil would blow it out of the riser like a cork in a hose.
假如他能实现这一目的，其油压也会使它脱离立管，如同水龙带冲飞软木塞那样。
The pressure fluctuation of the riser first increases then decreases with the superficial gas velocities;
立管压力波动幅度随气相折算速度的增大先增大后减小；
According to particle fluiding principle, we revamp the pilot scale test riser to make it operate smoothly in the boosting pressure.
本实验根据流态化原理改造了原有的提升管中试实验装置，使其可以在加压条件下稳态操作。
Based on analytical method, the paper shows that raising the length of a riser can elevate the water-hammer pressure and reduce the fluctuation of water level effectively in surge tank.
通过理论和解析方法讨论连接管较长时，其内水体惯性对调压井水锤压力和水位波动的影响。实例分析表明：连接管长度增加可使调压井水锤压力升高，水位波动幅值减小。
