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。

In the measurement of sound absorption coefficient in random incidence and determination of sound power levels of noise sources, the reverberation room is used very extensively.
The noise-extracted signal which is reconstructed by the revised wavelet coefficient could clearly reflect the time difference between incidence wave and reflection wave.
