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.
