摘要：
A wave-packet method is proposed to study evolution the behavior of disturbances in 3-D boundary layer on a swept plate. It is proved that the constant-phase lines are equivalent to the streaks observed in flow-visualization experiment and the asymptotic solution of wave-packet equation can give accurate conditions for e(N) method.
