微分方程及其中心流形方法的自动化简

On Simplification Automatically of Differential Equation and the Central Manifold Method

计算机代数是应用数学的一个边缘学科 ,应用 Mathematica系统的强大的符号运算功能以及该系统提供的控制语句 ,自动实现在平衡点附近降低微分方程阶数和实行中心流形方法 ,并将该处理过程做成相关的软件包 ,简便。

We have realized automatically in cutting down the degrees of differential equation and in carrying out the central manifold method in this paper which would use powerful symbolic operation and control sentences provided by Mathematica system. The author integrated into packages which can be expanded.
