1 ?升角 ... 钟表也是一种精密复杂的仪表,关于它的研究也建立了很多理论,包括定理、公式和计算,尤其是在擒纵机构方面的, 升角 ( Lift angle )就是其中之一.

“Most aerodynamic things take off at very gradual angles, but this has a very striking, very powerful lift angle, ” Swartzlander says. Swartzlander says：“大多数空气动力装置起飞的角度很平缓；而这样的装置起飞时角度变化非常剧烈，非常惊人。” - 2
Lie on the bed and lift your leg at the Angle of 45 degree, then bent your knees slowly and then return to the original position. Repeat this move for 100 times. 平躺在床上，提起腿到45角位置，再慢慢地弯曲膝盖，然后恢复到最初的平躺状态，这样是1轮，重复这个运动100次。 - 3
This effectively "pulls" the air around the leading edge, thus preventing the stall up to a much higher Angle of incidence and lift coefficient. 这将有效地“拉”前沿周围的空气，从而防止失速到一个更高的入射角和升力系数。
