摘      要：By extending the minimum spanning tree(MST)clusterization algorithm for the binding energy cut,the isospin asymmetry dependence of directed flow for isospin sensitive isobar pairs(neutrons-protons,3H-3He) is studied from low towards high incident *** modified clusterization method(MSTB) has the advantage to identify the fragments at quite early *** enhances(reduces) the production of free nucleons(fragments) over MST *** directed flow of isobaric pair3H-3He is more sensitive towards isospin asymmetry caused by MSTB than isobaric pair *** sensitivity becomes quite strong towards the high incident energy and neutron-rich reaction *** conclusion,the inclusion of binding energy in clusterization method for the flow studies has been uniquely important for understanding the isospin physics,especially for high density behavior of symmetry energy.
