摘　　要：The transport of solar flare particles in the corona is studied.Considering the problems in terms of the characteristics of a sunspot group producing solar cosmic rays and solar flare processes,we find that formation of the fast propagation process is associated with annihilation of sunspots in the group with magnetic multipolarity.The slower propagation process depends on magnetic irregularities in the corona,and the evolution of the transport is related to the flare processes.Equations for the coronal transport are proposed and their initial and boundary conditions are given.The predicted results agree with the main observational features.
