  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. The cylinders and the screw stems of the extruder are made of high quality alloy steel with optimum hardness and strong corrosion resistance after nitrogen treatment and precision finishing. the auxiliary machine has a plat from working table for making operation easy and is equipped with bubble stabilizing ring

    擠出機的機筒螺桿均採用優質合金鋼，經氮化和精密加工。具有最佳的硬度和耐腐蝕性。輔機設平臺工作臺，使操作更方便，並配置定泡圈。
  4. Because of the place obstruction of corrosion products in the surface of the alloys, while corrosion time is at 120 minutes above, the corrosion rate descends to the stable value in 48 hours

    當腐蝕浸泡的時間大於120分鐘后，腐蝕產物在鋁合金表面產生了明顯的位阻作用，從而使腐蝕速率逐漸下降，直至48小時后，腐蝕速率趨於一相對穩定的數值。
  5. 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。
