摘　　要：By means of the multilinear variable separation(MLVS) approach, new interaction solutions with low-dimensional arbitrary functions of the(2+1)-dimensional Nizhnik–Novikov–Veselovtype system are constructed. Four-dromion structure, ring-parabolic soliton structure and corresponding fusion phenomena for the physical quantity U =λ(lnf)_(xy) are revealed for the first time. This MLVS approach can also be used to deal with the(2+1)-dimensional Sasa–Satsuma system.
