Abstract：
Based on the electroweak unified standard model,the probability P _ifor the production of i-quark jet (i=u,d,c and b)in e ⁺e ^－annihilation has been studied.The probability P _iis a function of energy s.The calculated component ratios of P _u:P _d:P _s:P _c:P _bare 4:1:1:4:1 for s<30GeV.7:9:9:7:9 for s=m _z=91.16GeV and 1:1:1:1:1 for s=78 and 117GeV,respectively.Using P _cand P _b,we whave calculated the yields of charmed and beautiful mesons in e ⁺e ^－annihilation at s=10—178GeV.
