By comparing and analysing, we obtain the variation of the fraction of volume of the vapour inside pump and the variation of efficiency. Thus we know the anti-cavitation and efficiency of the pump how were influenced by different methods of generate blades. The results are good reference for engineers majoring on hydromechanical mechanism

螺旋桨采用离散涡环法，将桨叶表面和桨毂表面离散为一系列双曲四边形，在四边形网格中布置集中涡环和线源分布，根据物面条件建立方程得到涡和源汇分布的强度。

I've heard good feedback on other JOOLA blades from people whose opinion I value, so I don't see why the K series should be any different.

不考虑那些市场炒作因素，设计者一定是做了些有用的事情，自从K系列受到论坛板油们的显著关注以来，我听到了不少关于其他尤拉底板的良好反馈，所以我看不出K系列有多少不同。

The 16 noded relative degree of freedom shell element is discussed and used to mesh the blades of the runner.

考虑到16结点相对自由度壳元能很好地描述薄壳和厚壳的性质，而且和三维实体单元的联接也相当方便，本文采用该种单元对水轮机叶片进行离散，并通过样条插值获得叶片有限元网格结点的三维坐标。

Then comes the more powerful CH-47B with the Lycoming T55-L7C engine, which was introduced by Boeing after a production run of over 350 CH-47A's. On the B model there are nonsymmetrical rotor blades to increase the stability.

因此波音公司在推生产了350架CH-47A后，推出了更加强劲的配备莱克明T55-L7C发动机的CH-47B型。B型为提高稳定性，还配备了非对称性的旋翼桨叶。

Leaflet blades oblong to oblanceolate; plants erect.
