Kortewey-de Vries方程的孤子解

A method to find the solution of kortewey-de-vries eqution

利用一维波动方程行波解的形式,通过变量替换,再引入双曲正切函数作为独立变量并利用其独特的微分关系给变换,将Kortewey-de Vries方程简化为常微分方程,由此得出它的解。

The article made use of traveling ware solution of one dimentional undulat eqution, througy alternate, then to introduce hypertangent, as new variable and make use of infinitesimal connections of it, with analternate. Kortewey -de Vries eqution is simplified to ordinary infinitesimal eqution to find the solution of Kortewey-de Vires eqution.
