摘要:引入“秩”的概念,证明了“秩”同类的非线性发展方程具备Jacobi椭圆函数展开形成的解,而“秩”异类的非线性发展方程不具备此类型的解,但不论“秩”同类还是异类的非线性发展方程都可能具有双曲正切函数及多种形式的双函数展开形式的解,并以“秩”异类的弹性介质中非线性波方程为例对该结论加以证明.

关键词: 双曲函数法, 行波解, 秩, 弹性介质

Abstract: The Jacobi elliptic function expansion method can’t be applied to the “rank” different kind of nonlinear evolution equation was proved by introducing a concept of “rank”.Moreover,the tanh function and many kinds of the double function expansion method are suitable to solve not only the “rank” same kind but also the “rank” different kind of nonlinear evolution equation by extended the proof.

Key words: hyperbola function method, traveling wave solution, rank, nonlinear wave equation in elastic medium
