摘要
研究了一类非线性尘埃等离子体孤波解.首先对无扰动情形下的孤波解作了阐述,接着用同伦映射方法,构造了一个迭代,并求出到了非线性尘埃等离子体扰动单孤波的行波解.最后得到了对应模型的单孤波的各次近似解.
A class of nonlinear solitary waves in dusty plasma is considered. Firstly, a non-disturbed solitary wave solution is stated. Then the iteration is constructed by using the homotopic mapping, and the traveling wave solution of the nonlinear single-disturbed solitary waves in dusty plasma is obtained. Finally, every degree of approximate solutions for corresponding single solitary wave model can be found.
