The asymptotic structure of a turbulent boundary layer 
on a plate with a boundary-layer distributed suction, consisting of 
a suction zone, a viscous zone, a buffer zone, a velocity-defect zone, 
a Corrsin superlayer, and a irrotational-flow zone, has been determined. 
The analysis was carried out within the framework of the Reynolds 
equations with the use of the combined method of different scales 
and joined of asymptotic expansions. The Corrsin superlayer was interpreted 
as a discontinuity of turbulent stresses.
