Abstract：
In recent years,some short time enhancements of cosmic ray paticles during large solar flares(GLE)were recorded by neutron monitor at sea level and underground muon detector at different depths.The energy regions concerned were in several hundred GeV,even in few TeV.It is disccused in this paper,that the flux enhancemengt in TeV region may be due to the re-acceleration of the galactic cosmic rays in the period of large solar flares.Because of the very steep energy spectrum of cosmic rays,if only 10% cosmic ray paticles are re-accelerated with energy increment of several hundred GeV,the cosmic ray flux in TeV region could increase considerably.
