This paper studys the stability of nonlinear systems in two particular critical cases. In a case, the linear systems at the equilibrium point of interest is assumed to possess a simple zero eigenvalue. In the other case, it is assumed to possess a complex conjugate pair of simple pure imaginary eigenvalue.

本文基于中心流形定理研究了非线性系统在两种特殊临界情形下的稳定性问题，一种是与它相应的线性系统在平衡点仅有零特征根，另一种是与它相应的线性系统在平衡点仅有一对共轭的纯虚数特征根。

This paper studies how to define corresponding pulse transfer function D′ of digital controller, while there are zeros of conjugate complex numbers or negative real number in D, poses a solution method and gives comparative analysis for three different situations.

本文对D中含有共轭复数零点，或负实数零点时，如何确定数字控制器的相应脉冲传递函数D′的问题进行了研究，提出了解决方法，通过实例对三种不同情形进行了对比分析。

In the case of complex field, many authors discussed the problem, but complete classification table did not appear.

在复数域的情形，该问题已被许多文献广泛研究，但并未给出完整的分类表。

The central goal of this work is trying to generalize the above result to the Higgs version case, which should be helpful to the study of some question, say variants of the Kobayashi-Hitchin correspondence. The theorem to be proved here is the followingTheorem 02: Let M be a compact complex manifold of dimension m with a Hermitian standard metric g and let be a Higgs bundle over M.

本文的一个主要的目的是把上面的定理推广到E是—Higgs向量丛的情形；这一结果的意义在于在研究与Kobayashi-Hitchin correspondence相关的问题，如考虑Kobayashi-Hitchin correspondence的形变展现它的作用。

These methods have related to all of fields of AN science, and have got great effect in specific fields and states, but these all meet difficulties when processing huge quantity data with complex data type.

这些方法所涉及的领域几乎遍及人工智能科学的方方面面，而且在特定的领域中，特定的情形下取得了良好的效果。

A fast generalized complex sphere decoder is proposed for under-determined MIMO systems with fewer receive antennas than transmit antennas in this paper.
