Pitch controller: to maximize lift as the wind speed changes, a controller can automatically rotate each blade anywhere from a fraction of a degree to multiple degrees per second.

间距控制：为了最大限度地根据风速变化提升发电效率，新型风力发电机上的控制器每秒钟都能够对每一片风叶进行任何角度的调整。

Since this method adopts non-linearized theory of the lift coefficient curve of the blade section and multiple streamtube model, and has revised the aspect ratio influence, so it has wide suitability.

这个方法采用了叶型升力曲线的非线性理论和多流管的理论模型，并对展弦比的影响进行了修正，从而具有广泛的适用性。

The novice can withstand linear progression, meaning, they can focus on getting strong on each lift multiple times per week.

新手可以承受线，也就是说，他们可以集中精力于每部电梯越来越强烈每周多次。

The analyst noted that Pfizer still trades at a lower-than-average industry multiple, despite a 25% lift since early December thanks to a strong fourth quarter and a dividend hike.
