利用推广的F_展开法,研究了(2+1)维ZK方程,获得了该方程的一些行波解和双周期波解.当模数优-0和m-1时,得到相应的单周期波解和孤立波解,从而丰富了该方程解的范围.
Based on the expanded F-expansion method,the (2+ 1)-dimensional ZK equation is studied. As a result,some new travelling wave solutions and doubly periodic wave solutions are obtained. When the modulus m--0 and m--l, the corresponding single periodic wave solutions and solitary wave solutions are got. Thus, the solutions of (2 + 1)-dimensional ZK equation have been enriched.
