Abstract：
In recent years, some short-term enhancements of cosmic ray particles during large solar flares (GLE) were recorded by neutron monitors at sea level and underground muon detectors at different depths. The energy regions concerned have reached to several hundred GeV, even to a few TeV. It is discussed in this paper that the flux enhancement in the TeV region may be the result of re-accelerations of the galactic cosmic rays during large solar flares. Because of the steepness of the energy spectrum of cosmic rays, the re-acceleration of a small part of cosmic ray particles in the GeV region may induce the obvious enhancements of cosmic ray flux in the TeV region.
