摘　　要：研究了平板混合边界层厚度的近似解求法,通过对一般平板混合边界层的近似解的求解方法的掌握,得出了另外一种可以提高精确度找到混合边界层厚度近似解的方法.先按全板层流估算δcr,再根据δcr值推算A′位置,此点作为紊流边界层的起点,最后采用紊流边界层计算公式计算.Methods of approximate solution of mixing boundary layer＇s ply on flat plate is mainly researched. Many books of fluid Mechanics were studied. In many books methods of approximate solution of mixing boundary layer＇s ply on flat plate are mastered by reading those. New methods of approximate solution of mixing boundary layer＇s ply on flat plate are put forward. Estimating δCr on flat plate by laminar flow. Then on the basis of δCr estimating A＇, A＇ is regarded as initial point in boundary layer of turbulent flow. Making use of couputing methods of boundary layer of turbulent flow computes.
