The result shows: short splitter has weak influence on the suction pressure distribution, leakage flux and the position leakage vortex rotated on the tip of principle blade.

结果表明：短弦长小叶片对大叶片吸力面负荷分布、泄漏量以及泄漏涡的产生位置的控制作用较弱；

In addition, the tip of the blade is always thinner, which lead to deformation easily, so there is a higher demand for the stability of the machining system.

此外，桨叶叶梢部分较薄，加工中易引起变形，这给加工系统的稳定性提出了更高的要求。

The efficiency of pump will be reduce with the increase of tip clearance of blade.

泵的效率随轮缘处间隙变大会有明显减小。

Thus, 30% from the tip of leaf blade was the best measuring position.

因此，距叶尖30%处是最合适的测定位置。

The morphological abnormalities were observed in the hyphae body of V. paulowniae after treatment of the pathogen with the fermented broth of S-921 strain, with significantly increased amount of vacuole, condensed cytoplasm, inflated hyphae tip and loss of pathogenicity of the pathogen.

经S-921菌株发酵液浸泡处理的泡桐腐烂病病原菌菌丝体，会出现大量液泡，原生质凝集，菌丝尖膨大等异常形态，并失去致病力。

Mixed flow compressor achieves better performance and lower tip leakage loss, and flow field at outlet is more uniform in mixed flow impeller than centrifugal impeller.

计算结果表明在高比转速情况下，斜流叶轮有利于减弱叶尖泄漏损失，改善叶轮出口均匀性，提高叶轮效率和级效率。

Five turbine tip clearance loss models, widely used in engineering practice, were analyzed and compared comprehensively on the basis of the CFD numerical simulation.

这里基于CFD数值计算的结果，对5种工程上常用的涡轮叶尖间隙流动损失模型进行了全面的分析比较。

Keep as much line off the water as possible by raising the rod tip and stripping in line as the streamer drifts towards you.

当饰带毛勾向钓手位置漂流时，尽可能提高竿尖及收丝使飞蝇线离开水面。

As the fly passes and drifts downstream, lower the rod tip and feed line to the drift.

当饰带毛勾漂流到下游时，降低竿尖和增放飞蝇线使饰带毛勾继续漂流。

The tip of her line is her bait.

这个末端就是她的饵儿。
