  1. Cavitations in foreign hydraulic turbines appear in clear water condition, so its destructive extent is not far more serious than in yellow river in our country. stronger stiffness and more agility are required for special - purpose robot for hydraulic turbine repair used in our country, especially robot for polishing after weld. foreign robot for hydraulic turbine repair could not satisfy our working require, so we develop special - purpose robot system that is used to polish and weld repair cavitated flow path surfaces of hydraulic turbines on all locations

    國外水電站的水輪機汽蝕是在清水條件下產生的，其破壞程度遠不及我國黃河等水域嚴重，用於我國水輪機修復工作的專用機器人，特別是補焊后承擔打磨的機器人，要求有更強的剛度和更大的靈活性，國外水輪機修復機器人滿足不了我國水輪機修復工作要求，因此我們開發了用於在機坑內對水輪機空蝕磨損破壞表面進行修復的「水輪機修復專用機器人」 。
  2. Fluid machinery in these areas is damaged due to cavitation and sand abrasion, which has threaten directly the safety operation of hydraulic and hydroelectric engineering, causing huge economic losses. the research, therefore, on the combined effect of cavitation and sand abrasion is of great significance. the researchers at home and abroad have done a lot of work on this issue

    我國許多河流的含沙量較大，如著名的黃河幹流年均含沙量達37 . 9m ~ 3 / s ，黃河三門峽的年平均輸沙量達16億t ，這些地區使用的泵、水輪機等許多流體機械都在夾沙水流的作用下，受到了沙粒磨損與空化剝蝕的聯合破壞，這種破壞直接危害了水利水電工程的安全運行，造成了巨大的經濟損失，因而對含沙水流條件下空化剝蝕與泥沙磨損聯合作用進行研究有著很大的工程實際意義。
  3. 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。
  4. Based on the comparison made among the characteristics of different kinds of the blade materials, the relationship between the material characters and the flow attack angle is explained, and then the breakage mechanism of the combined effects from both the clearance - cavitations and the erosion of leakage flow are expounded comprehensively

    通過對不同材料的特性比較，解釋了材料特性與沖角之間的關系，綜合闡述了泄漏流動所引起葉片正面頭部空蝕與磨損聯合作用產生破壞的機理。
  5. During the long active service time, the structure maybe presents all kinds of structural damage because such reasons as tired accumulating, environment corroding and natural calamity function, etc. in order to find those damages early, nip in the bud, and lower the damage of accidents, it is great meaning full to research the technique of online damage monitoring of the long - span lattice roof structure

    結構在服役期間，由於疲勞累積、環境腐蝕及自然災害等作用，可能出現結構損壞，因此，為了能夠及時發現問題，防患於未然，把事故損失降到最低點，在結構正常使用情況下，對大跨空間網格結構進行在線損傷監測研究，就顯得極有現實意義。
