摘要 利用李群分析方法研究了高阶非线性薄膜方程.首先,利用无穷小生成元方法得到了该方程的李代数及其最优系统,然后对方程进行约化,最后获得了一些具有特定物理意义的相似解. In this paper,Lie symmetry analysis approach is developed to study a higher-order nonlinear thin film equation.Using the infinitesimal generators,the Lie algebras and its optimal systems of the higher-order thin film equation are derived. The equation is then reduced to the ordinary differential equations.As a result,some physical interest solutions are obtained and discussed.
