Once the trailing edge vortex stays at the trailing edge the interaction of complex vortex structures occurs and no longer has a beneficial effect on the suction peak induced by the stall vortex.

后缘涡在翼面上驻留时，各涡产生复杂的相互干扰，对失速涡在上翼面产生吸力有不利影响。

A high suction peak is induced by the stall vortex as the trailing edge vortex sheds downstream smoothly.

后缘涡顺利地从后缘脱落时，失速涡在上翼面能诱导出较大的吸力。
