Abstract：
In this paper we investigate the behavior of the B-S wave function as the squared momentum on one leg becomes infinte while the squared momentum on the other leg remians fixed by using the property of asymptotic freedom in QCD. Using the obtained wave function we compute the cross section of the process e ⁺+e ^-→ π+q+ q(where the pion has large transverse momentum perpendicular to the axis of a stratonic jet). We find that the contribution of this process to the cross section of e ⁺+e ^-→hadrons is much smaller than the process e ⁺+e ^-→g+q+ q.
