Abstract：
We show that the near correlation in rapidity is consistent with the requirements of QCD, and completely determines the combination rule of quarks. We give the formulae for calculating yields of mesons, baryons and antibaryons, which are produced by a stochastic accumulation of quarks with similar rapidities. Using it to e⁺e^－ annihilation, the observation of recently unexpected copious production of baryons is explained naturally.
