Abstract：
Generally,the solar high energy particles in the flares are believed to be accelerated in two stages:acceleration by abrupt release of magnetic energy in the first stage and coronal diffusive shock wave or stochastic acceleration in the second stage.In this paper,we consider the diffusive shock wave acceleration in gradual solar flare associated with fast coronal shock wave. The results indicate:(1) the characteristics of the particle distribution with time depends on the momentum and with the incresing of transition time,the distribution increases to maximum quickly and turns to decrease them the higher energy,the more time of moving to maximum;(2)the corresponding time integral spectrum is proportional to the power of the particle momentum.The possibility of accelerating particles to high energy range is also discussed.
