摘要:

针对非线性数学物理研究中应用广泛的Newell方程的精确解问题,采用扩展的齐次平衡法获得Newell方程的一组Backlund变换,并利用此Backlund变换得到2组带有任意参数的精确解.这些结果与通过双曲正切法、试探函数法得到的结果进行比较,发现用Backlund变换得出的解的形式更加丰富,肯定了该方法的可行性和有效性.

关键词: 齐次平衡法, Backlund变换, Newell方程, 精确解

Abstract:

For the solutions of Newell equation,which is widely used in nonlinear mathematical physics,the Backlund transformation and two groups of exact solutions with arbitary paramaters are obtained through the method of extended homogeneous balance. Compared with the results obtained through hyperbolic tangent method and the trial function method,the solutions in this paper are richer,and the method is feasible and effective.

Key words: homogeneous balance method, Backlund transformation, Newell equation, exact solution
