摘要针对文家坪磷矿地下开采岩体移动变形问题，给出了用于预测分析地下开采引起地表移动变形的双曲正切函数模型。 - One of most effectively straightforward methods to construct travelling solitary wave solutions is tanh - function method . the algorithm is based on the fact that the solitary wave solutions are essentially of a localized nature . seeking solitary wave solutions which are in terms of hyperbolic tangent function gives a nonlinear system of algebraic equation
寻求非线性演化方程孤波解的双曲正切方法是直接代数方法中最为有效的方法之一，其基本原理是利用非线性演化方程孤波解的局部性特点，将孤波解表示为双曲正切函数的多项式，从而将非线性演化方程的求解问题转化为非线性代数方程组的求解问题。 - Chapter5 : the recently developed method of hyperbolic tangent function expansion is extended and new function transformation is applied to construct some new solitary solutions of kdv equation and klein - gordon equation and the jacobi elliptic function expansion method , which is advanced in 2001 , and the extended method of doubly jacobi function expansion are used to construct the exact solutions of a kind of nonlinear evolution equations
第五章对近年来发展起来的双曲正切函数展开法加以改进，采用新的变换函数，得到了kdv方程和非线性klein - gordon方程的一些新的孤立波解。其次，分别采用2001年提出的jacobi椭圆函数展开法和本文由此扩展而来的双椭圆函数展开法，求解了一大类非线性发展方程，得到了一系列新的周期解。
