英文摘要	The isospin equilibration process in multinucleon transfer reactions is investigated by using the improved quantum molecular dynamics model. The collisions of Xe-124 + Pb-208 at near-barrier energy are studied with different symmetry energy coefficients. We find that the neutron transfer is enhanced at the early stages of the collisions under the strong symmetry potential. The neutron's transfer takes place at an earlier stage than the proton's. The trajectory of neutron flow is along the low-density path from the target to projectile. The average N/Z values of the primary products in the Ni-58 + Pb-208 reaction are also investigated and compared with available experimental data. It shows that the average N/Z values of the projectile-like products increase rapidly with increasing mass transfer. In the quasielastic collisions, the isospin equilibration process is incomplete due to a short contact time between the reaction partners. The complete isospin equilibration events take place in symmetric quasifission reactions.
