Fractality of pomeron-exchange processes in diffractive DIS
  By using Monte Carlo simulation of pomeron exchange model, the dependence of the fractal behavior of the pomeron induced system in deep inelastic lepton-nucleon scattering upon the diffractive kinematic variables is found rather robust and not sensitive to the distinct parameterization of the pomeron flux factor and structure function. Based on this characteristic fractal plot, a feasible experimental test of the phenomenological pomeron-exchange model in DESY $ep$ collider HERA is proposed.
