| Abstract: | A class of exact solitary wave solutions for the(3 1)-dimensional Zakharov-Kuznetsov(ZK) equation which contains three arbitrary variable coefficients are obtained by using the WTC method.The results indicate that the coefficients of the equation will not change the wave amplitude,but change the wave velocity. |
