(2+1)维破裂孤立子方程的周期孤立波

摘要

With a logarithmic transformation,the breaking soliton equation is turned into three linear type,(2+ 1)-dimensional breaking soliton equation is solved by using the new test function,and some new cycle solitary wave solutions are gotten.Obviously,this new method can be applied to solve other type of nonlinear evolution equations as well.%利用对数变换把破裂孤立子方程化为三线性型,然后使用新的测试函数来求解(2+1)维破裂孤立子方程,并得到新的周期孤立波.显然,该方法适用于相当一部分发展方程.
