摘　　要：The threshold anomaly (TA) in heavy-ion elastic scattering was first observed in 1983. The TA may be described mainly by the coupling of the elastic scattering to other reaction channels which produces an attractive polarization potential ΔV, leading to a real potential V=V0+ΔV, where V0 isThe threshold anomaly （TA） in heavy-ion elastic scattering was first observed in 1983.
