We obtain an analytical expression for the quantity, [`d](x)-[`u](x), which measures the SU(2) asymmetry in the light quark sea, by
solving analytically the (non-singlet) evolution equation of QCD, for which Debye's
steepest descent method in its orginal rigorous form is used. Our solution is consistent
with the recent NMC data concerned, and Regge-behaved as well.
