本文研究了一类非线性浅水波系统,首先构造了相应的泛函. 其次选取Lagrange乘子,再用改进的广义变分迭代方法,得到了相应模型的行波近似解析解.
In this paper, a class of wading wave system is considered. Firstly, the corresponding functional is constructed; secondly, its Lagrange operators are selected. Then, using the modified generalized variational iteration method, the corresponding traveling wave approximate analytic solutions are obtained.
