In reality, the air traveling above reaches the wing's trailing edge much faster than the air beneath.

实际上，上方的空气到达机翼后缘的速度比下方的空气快得多。

For the air molecules above to reach the wing's trailing edge in the same instance as those that split off and went below, air must travel faster above, creating a pocket of lower pressure that lifts the plane.

为了使上方的空气分子与那些分裂并进入下方的空气分子在同一情况下到达机翼的后缘，空气必须在上方更快地移动， 从而形成一个低压袋来提升飞机。
