The weak Whitney class map of projective module of rank one is investigated from the view of intersection theory.Particularly,for split projective module Q≌l1(+)l2(+)…(+)ld,it is proved that E0(Q)=(-1)dE0(Q*),where E0(Q) and E0(Q*) are weak Euler class of projective module Q and its dual module Q* respectively.This is the algebraic analogue of duality theorem for Chern class of vector bundle in topology.
