In the range of high tip-speed ratio the results calculated by this method are closer to experimental data than that computed by momentum theory.

在高尖速比范围内，本方法给出的结果比动量理论给出的更加接加接近实验数据。

Photo Tip: If you use a tripod and a very slow shutter speed to shoot a moving subject, you can get a dramatic contrast between sharp and blurred detail.

拍照小技巧：如果用上三角架，然后放慢快门速度来拍摄移动的对象，你可以的到一张有强烈对比的照片，有清晰的部分，又有模糊掉的细节。

To the grid connected wind turbine, the purpose of controlling it working at optimal tip speed ratio or about is to capture maximum wind energy.

对并网型风力机，控制其在额定风速下运行在最佳叶尖速比或其附近，主要是希望它能捕获到最大的风能。
