摘要
用微分方程动力系统方法研究Dullin-Gottwald-Holm(DGH)方程,发现其存在无界孤子,并在一些特定的参数条件下,得到了无界孤子的函数表达式,同时通过无界孤子的解,用数学软件Mathematica 7.0模拟出了其无界孤子的平面曲线图.
The Dullin-Gottwald-Holm equation was studied with the dynamical system theory of differential equation.It is found that the Dullin-Gottwald-Holm equation has unbounded solitons.And not only its exact function expressions under some parameter conditions but also the planar graph have been obtained through numerical simulations by using mathematical software Mathematica 7.0.
