摘要 Tanh-函數(shù)法是一種直接和有效處理非線性微分方程的代數(shù)方法，本文利用Tanh-函數(shù)法，并且通過Maple數(shù)學(xué)軟件的輔助計(jì)算,求出非線性微分方程的精確解,獲得了一些與現(xiàn)有參考文獻(xiàn)中結(jié)構(gòu)不相同的精確解,本文用的方法還可以用來解決部分非線性微分方程（組）. 關(guān)鍵詞：Tanh-函數(shù)法；齊次平衡原則；耦合的；精確解；Kdv方程．
ABSTRACT Tanh-function mathod is a direct and effective treatment of nonlinear differential equation,In this paper,the many solution of nonlinear differential equations are studied by using combined Tanh-function mathod .And numerical simulattion by opeating Maple.Access to with the references is not the same as the exact solution ,This show mathod can also be used to solve partial nonlinear differential equation.
