摘要
New forms of different-periodic travelling wave solutions for the （2＋1）-dimensional Zakharov-Kuznetsov （ZK） equation and the Davey-Stewartson （DS） equation are obtained by the linear superposition approach of Jacobi elliptic function. A sequence of cyclic identities plays an important role in these procedures.
