The enlarged new absorption cross section of J/psi by pion and rho mesons were put into the hadron and string cascade model, JPCIAE, and the J/psi suppression factors in p-A, O-U, S-U and Pb-Pb minimum bias collisions at 200 AGeV/c were calculated with nuclear absorption mechanism only. The results seem to indicate that, with new enlarged cross section it is still hard to change the aspect that nuclear absorption itself could not easily account for the J/psi anomalous suppression in Pb-Pb collisions.
