Isospin effects,especially from system isospin asymmetry and fragment isospin asymmetry,are introduced into transverse flow extraction mainly via various physical quantities such as symmetry potential,NN cross section,and coulomb force.Since lots of efforts have been carried out to study the isospin effect by comparing the colliding pairs with different isospin in both experiment[1-5]and theoretical calculations[6-8],in these paper,we focus on the fragment isospin effect on the flow for isobaric fragments.
