Abstract：
Based on the electroweak unified standard model,the probability P_i for the production of i-quark jet (i=u,d,c and b)in e⁺e^－ annihilation has been studied.The probability P_i is a function of energy s.The calculated component ratios of P_u:P_d:P_s:P_c:P_b are 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_c and P_b,we whave calculated the yields of charmed and beautiful mesons in e⁺e^－ annihilation at s=10—178GeV.
