摘　　要：The evolution of shower parton distributions in a jet is investigated in the framework of a quark recombination model. The distributions are parameterized and the Q^2 dependence of the parameters is given by polynomials of In Q^2 for a wide range of Q^2The evolution of shower parton distributions in a jet is investigated in the framework of a quark recombination model.
