利用变量替换和坐标变换方法,建立了一个新三阶可积孤子方程与著名的KdV方程之间的联系.应用KdV方程的非零解和变换关系,获得了新三阶可积孤子方程的孤立波解、周期波解和有理解.
In this paper, the relationship between well-known KdV equation is established by a set of a new third-order integrable soliton equation and transformation. Some exact solutions of the new integrable equation are obtained by this transformation and solutions of KdV equation.
