摘要：

A new parametrization for parton distributions in the real photon is obtained by solving the inhomogeneous leading order Altarelli-Parisi equations for the photon case. All the presently available data on the photon structure function are used to fit the quark and gluon distributions. The dependence of the results on the initial conditions for the evolution, the starting value of Q2, Q0(2), and the shape of the gluon distributions in particular, is investigated. Expectations in the HERA kinematical limit are discussed.
