  1. In order to make sure the point where an empty bubble breaks and breakage function on the solid wall due to cavitatin, some exploration work is performed

    為確定空泡潰滅點，並由此確定空蝕對固壁的破壞作用作了探索性工作。
  2. Due to its complexity of the problem, the theories and experiment results obtained are discrepant, and some of them are even contrary one another. started from the influence by movement rules of small cavities and solid particles, the mechanisms of combined effect of cavitation and sand abrasion are study in this thesis from the aspect of the turbulent coherent structure near the wall. first, a dynamic equation is established for a single spherical bubble and single spherical sand under the non - turbulent coherent structure near the wall, and then a dynamic equation established under the turbulent coherent structure near the wall

    首先從理論上推導出在典型湍流邊界層模式的非擬序結構下空泡與固體顆粒的近壁區運動方程，然後推導出湍流近壁擬序結構作用下的空泡與固體顆粒的近壁區運動方程，再將兩種不同條件下的的運動方程進行比較，指出湍流近壁區的擬序結構對空蝕與磨損的發生具有決定性的意義，即正是由於擬序猝發作用的存在，才使得空泡、沙粒對壁面的空蝕與磨損作用得以發生。
  3. When the propeller operates in the spatially non - uniform velocity field behind the ship, the unsteady cavitation on the blades often causes the vibration of ship structure, the propeller noise and the cavitation erosion on the blade

    在船尾非均勻流場中工作的螺旋槳，常常由於槳葉上產生了非定常空泡，導致船尾振動和螺旋槳噪聲，致使槳葉表面出現空泡剝蝕。
  4. Through comparison, it can be seen that the turbulent coherent structure near the wall influences directly the striking effect of the bubble and sand. a new proposal is put forward at the end of the thesis that the destruction caused by the combination of cavitation and sand abrasion can be mitigated by means of controlling the turbulent coherent structure near the wall

    最後用有關的結論對過去的空蝕與泥沙磨損聯合作用的一些試驗觀測結果進行了定性的分析、評述，並提出通過控制擬序結構的發生以達到控制空泡、沙粒對壁面的沖擊作用是減輕磨蝕破壞的一條新的途徑。
