	4.	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 国外水电站的水轮机汽蚀是在清水条件下产生的，其破坏程度远不及我国黄河等水域严重，用于我国水轮机修复工作的专用机器人，特别是补焊后承担打磨的机器人，要求有更强的刚度和更大的灵活性，国外水轮机修复机器人满足不了我国水轮机修复工作要求，因此我们开发了用于在机坑内对水轮机空蚀磨损破坏表面进行修复的“水轮机修复专用机器人” 。
	5.	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 通过对不同材料的特性比较，解释了材料特性与冲角之间的关系，综合阐述了泄漏流动所引起叶片正面头部空蚀与磨损联合作用产生破坏的机理。
	6.	This paper present an ideal and calculation method of the effective operating curve where cavitations characteristic is not change . based on the lifting - line and lifting - surface method , using effective operating curve to control the cavitation type and " new section " design method to extend the width of cavitation bucket . the width will almost increase 30 % than the common section 提出了保持剖面空泡特征不变的有效运转曲线的思想和确定方法，在升力线和升力面的基础上，应用有效运转曲线控制空泡类型，采用“新剖面”设计方法扩大空泡斗宽度，其空泡斗宽度比常规剖面增加近30左右。
	7.	In order to increase the energy dissipation of stepped spillway at iarge unit discharge , the integhty dissipater of aerated splitter pier and steppe characteristics is studied . because of verticaj diffhaion now by aerated splitter and impachng steppe 3 by drop flow , the air concentration and the energy dissipation efficiency are greatly increased ; the potentiality of cavitations is decrease . in special at large unit discharge , this effect is more obvious 掺气分流墩的增加，明显地改善了阶梯面上的压强分布，消除或减小了阶梯凹角内和立面上部的负压；由于掺气分流墩使水流纵向扩散以及挑流落下后在阶梯上的撞击，使水流的掺气浓度和消能率都得到较大的提高，降低了阶梯面空蚀的可能性，特别是在大单宽流量时，这种效果更为明显。
