Abstract：
We discuss in detail the combination rule of quarks controled by the nearest correlation in rapidity.The average yields of mesons,baryons and the multiplicity distribution produced by stochastic accumulation of N pairs of quarks have been given.Using the relationship between the average yields of quarks-pair and energy,which is in fact universal,we calculate the observed yields of meson,baryon and the multiplicity distribution in e⁺e^－ annihilation.The comparisons among our prediction,the experiment data and the negative binormial distribution are given.
