叶端是指叶片的上端，亦称先端、顶部、上部。植物种类不同，叶端形态差异很大。常见的叶端形状有：渐尖、急尖、尾状、钝形、微凹、倒心形，此外还有微缺、卷须状、芒尖、圆形、截形等。
叶端的软骨往往是软弱的，有一个更圆的角度。
The cartilages of the tip tend to be weak and have a more round Angle to them.
目的是在减少叶端漩涡，降低叶轮的流动损失，提高风力机的输出功率，将更多的风能转化为电能。
The above is the scale of our research. It aims to decrease tip vortexes, reduce the flow loss of the rotor and improve the output power of the wind turbine.
