These are exactly the same as the laminar boundary layer flows along a flat plate. And that, by using the existing exact solution of the laminar boundary layer equation for the boundary layer flow along a flat plate and appropriate boundary conditions. An exact solution of the laminar boundary layer equation for the laminar boundary layer between two parallel streams with different densities,viscocities and velocities is given elegantly.For the cases considered by Lock, the results obtained by the present method are compared with Lock’s numerical calculations in detail. 关 键 词：BOUNDARY kyer PARALLEL STREAMS Blasius SOLUTION
