摘要 本文导出了具高阶非线性项的Lienard方程的准确周期解并从理论上给予了证明,然后利用这些公式得到一大批具高阶非线性项的发展方程的各种Jacobi椭圆函数型的准确周期解,由此避免了一大类非线性发展方程求周期解时求解过程的重复。 In this paper, we obtain some formula for exact periodic solutions to Lienard equations with nonlinear terms of higher order, also derived are the exact periodic wave solutions to a sort of nonlinear evolution equations with nonlinear terms of higher order by those obtained formulae, the repeatation of similar processes are thus avoided.
