Abstract：
The pion fragmentational function is calculated.In high energy region,the asymptotic freedom perturbation theory is used.After passing through a certain distance the quarks break into hadrons because of confinement,which plays a role in the low energy region and pions must be considered as Goldstone boson and must be a result of dynamical breaking.In this article the fragmenta tional function in the low energy region is calculated with dynamical breaking mechanism.The result obtained for the fragmentational function is in agreement with experiments.
