The ignition process of combustible gas stream by a heated plate in the laminarboundarylayer was analytically considered and the limits of ignition were determined.
以此分析了炽热平板层流边界层内可燃气流的引燃，给出了描述引燃的着火临界条件。

Like in an infinite flow, we find that laminarboundarylayer, transition region and turbulent boundary layer also exist along a flat plate in open channel flow boundary layers.
An experimental study on the laminarboundarylayer instability and transition was carried out in a flat-plate boundary layer by means of controllable heat pulsing introduced into the critical layer.
