1. Also the inducer's pre-circumrotation, pre-promotion of pressure and anti-cavitation ability were studied.
同时，针对螺旋诱导轮的特殊结构，深入分析了它的预旋和预增压作用，以及自身良好的抗汽蚀性。

2. A hydraulic turbine is the device which turns kinetic energy of water into circumrotation power energy, and makes dynamotor working, then transfer energy to other place.
3. The circumrotation of roller in metal spinning forming is a important dynamic boundary condition. The speed of roller need to be determine in real time in the process of finite element analysis.
旋压成形中旋轮被动转动是一个重要的边界条件，在有限元分析中需要时实确定旋轮的转速。
