The excitation functions of quasi-elastic scatterings at backward angles were measured with high precision to study the mechanisms of heavy-ion reactions at near- and sub-barrier energies. The surface diffuseness parameters for the 16O+144,152,154Sm, 170Er, 174Yb, 184,186W, 194,196Pt, and 208Pb systems have been extracted by the single-channel and coupled-channels calculations, respectively. No anomaly was found in these quasi-elastic processes. The barrier heights and barrier distributions were systematically investigated for these systems. Moreover, the coupled-channels effects of neutron transfers with positive Q-value and the breakup effects of weakly-bound nuclei on the fusion processes were also studied for the 32S+90,96Zr systems and the 6,7Li, 9Be+208Pb systems, respectively.
