High water saturated vapour pressure leads to the more possible occurrence of cavitation phenomena in water hydraulic pump, and so as in sliding shoes hydraulic supporting without exception
水的高飽和蒸汽壓力使得水壓泵中極易發生氣蝕現象，滑靴靜壓支承也不例外。 -
Basically, the predicted cavitation phenomena coincides with those observed in the experiment for a corresponding model turbine, it indicates that the simulation can provide reference for the cavitation performance prediction of other turbines
數值預測的空化流動現象與模型水輪機空化試驗中所觀察到的現象基本一致，說明數值模擬結果可為水輪機的空化性能預測提供參考。 -
Unsteady separated flow, produced during the gate - opening period in the reverse radial gate tunnel of a high - lift shiplock, is characterized by negative pressure and high velocity as well as their intense fluctuations in space and time and could easily result in various harmful phenomena such as cavitation, gate vibration and sonic boom, which have been observed and confirmed by prototype and physical model tests
高水頭船閘輸水反弧閥門開啟過程中，后廊道內發生急變分離流，負壓、高速水流以及壓力與流速的劇烈時空脈動變化容易誘發空化空蝕、門振和聲震等有害現象已被原型觀測和物理模型試驗研究證實。 -
Because these harmful phenomena are closely related to the dynamic process of the flow, it is of great importance, theoretically and practically to the engineering design, to study the flow regime and predict the variations of flow velocity and pressure so that the hydrodynamic mechanism of cavitation and gate vibration could be analysed
由於這類有害現象的發生與水流的流動特性密切相關，探明閥門段水流急變分離的流態、預測流速、壓力時空變化規律，分析空化與振動的水動力學成因，在理論上和工程設計實踐上皆具有重要意義。
