In order to determine the Poincare normal form of linear operator in the operator differetial equation, we need to reduce the vector-value function to the two dimensional case on center manifold.

要证明以上的结论，我们所采用的方法是[24]中的Hopf分支定理所给出的判断Hopf分支存在性及分支周期解稳定性方法。

According to the discussion of the last chapter, we make use of a class of Null Dirac structure on the product Poisson manifold T*M×g* to do the Poisson reduction.

为此，我们利用了T*M×g*上一类Null Dirac结构来做Poisson约化。

Invariant manifolds are important for the study of dynamic systems. Since they are hard to he computed h analytical expression, the numerical method for approximating invariant manifold is an important mean.

不变流形在动力学研究的许多方面都有重要意义，由于不变流形很难通过解析表达式求解，对其做近似计算就成为重要的手段。

The study of numerical manifold method provides a mathematics base for some problems, such as seepage of rock slope, deformation and stability analysis.

对数值流形方法进行的研究，为岩石边坡渗流、变形与稳定分析等问题提供了数学基础。

At present, many known results are obtained only on one dimensional functional space, and the research on high dimensional space is little, only the continuous solutions are discussed on RN, neither the differentiate solutions on RN nor the solutions on abstract space and manifold.

在一维情形下，所涉及的函数通常具有较好的性质比如单调性，逆映射导数的LipschitZ性(在研究光滑解时通常需考虑)等，而第il页摘要高维空间上函数则不具有这些好性质，因此，讨论高维空间上的迭代方程要求在方法上作一些改进和突破。
