The soliton solutions and periodic solutions of (3+1)-dimensional Nizhnik-Novikov-Veselov equation
(3+1)维Nizhnik-Novikov-Veselov方程的孤子解和周期解

Dimensional Nizhnik-Novikov-Veselov equation was reduced by using traveling wave method.Some soliton solutions and periodic solutions of the model are obtained by using a simple transformation relation and exact solutions of the cubic nonlinear Klein-Gordon equation.
