螺旋桨理论设计 meaning in Chinese

theoretical design of propeller

To avoid or reduce these trouble induced by the unsteady cavitation , the theoretical design method for propeller and the blade section with the good cavitation performance are adopted to enlarge the cavitation bucket width and control the range and type of the cavitation on the blade . this enables propeller to operate in the non - uniform ship wake rather well
为了避免或减缓空泡带来的危害，采用螺旋桨理论设计方法和空泡性能优良的桨叶剖面来增加空泡斗宽度和控制桨叶空泡范围及空泡类型，以适应非均匀流场中螺旋桨工作的需要。
