摘要
在对一类正则长波方程定性分析的基础上,得到了其全局相图.由此推知,此类方程具有渐近值相同的钟状孤波解,并求得了其精确孤立波解,即此正则长波方程的同宿轨道.
By qualitatively analyzing regularized long wave equation, its global phase portrait, and come to the conclusion that the equation has kell-shaped solitang wave solution which asymptotic value is the same. Then we get its exact solitang wave solution, ie. homoclinic orbit of regularized long wave equation was obtained.
