Approximate solution of solitary wave for a class of generalized nonlinear disturbed dispersive equation
一类广义非线性扰动色散方程孤立波的近似解

The approximate solution for a class of nonlinear disturbed dispersive equation is considered using a simple and valid technique. We first introduce the solitary wave solution of the corresponding typical differential equation, and then the approximate solution of the singular solitary wave for an original nonlinear disturbed dispersive equation is obtained using the homotopic mapping method.
