  1. The prediction of propeller - induced hull pressure fluctuation in non - uniform flow is studied by using theoretical calculation and model experiment systematically. an intact method and computer program for the prediction of unsteady cavitating propeller - induced hull pressure fluctuation in non - uniform flow is set up in this paper. the measurement of propeller induced hull pressure fluctuation in depressurized towing tank carried out in this paper is the first time inland

    本文從理論計算和模型試驗兩個方面系統地研究了不均勻流場中螺旋槳空泡誘導的船體表面脈動壓力的預報問題，建立了一套完整的預報非定常空泡螺旋槳誘導的船體表面脈動壓力的方法和程序，並在國內首次完成了在減壓拖曳水池中進行空泡螺旋槳誘導的船體表面脈動壓力測試。
  2. In fact, the outlet flow of vane in the hydroelectric set is non - uniform flow for a variety of possible reasons. the flow is unsteady flow relative to vane and blade, and it is the main factor that affect self - excited vibration and dynamic characteristic of guide vane and hydraulic - turbine, which affect directly the power set to run safely and stably

    非均勻來流相對于導葉、葉片必然是一種非定常流。這種非定常流造成導葉和轉輪葉片的激振，是產生導葉和葉片動應力，改變它們頻率的最主要因素，而導葉和葉片的動力特性直接影響水輪機的穩定性。
