In history and reality, the contradiction between needs and limited resource always exists. From the view point of system-science, it can be concluded that:①The interaction among need-contradiction-ability is the perpetual force for enterprise evolution (and the evolution of other living systems). The improvement of "ability"is the process and result of evolution.②The competition and coordination among systems is the direct power for enterprise evolution. Competition produces various system actions. Coordination makes systems complement their functions with each other. The interactions of competition and coordination push enterprise into the flow of evolution and optimization.③The"stochastic fluctuation"of the system, which is accidental finding, is another force for enterprise evolution. It is a deterministic element in the process of the self-organization of enterprise.

在历史和现实中，需要和满足需要资源稀缺之间的"问题"是恒久存在的，从系统科学的角度可以演绎出：①需要一问题一能力三种异质要素的相互作用是企业进化（其它一切有生命系统进化）的永恒动力，"能力"的提高正是进化的过程和结果；②各系统间的竞争与协同是企业进化的直接动力，竞争产生多样化的系统行为，协同则使各系统间优势互补，竞争与协同交互作用推动企业呈现出进化与优化的趋势：③系统的"随机涨落力"即意料之外的发现与创新是推动企业进化的又一种动力，它是企业自组织过程中带有必然性的力量：④在解决"问题"中创新者的作用不可低估，但更为根本地说创新者只是"需要一问题一能力"这三种要素相互作用的载体，个体的创新是企业自组织过程的必然结果。

Under the cases of the linear interconnected systems with all its subsystems are one dimension, a theorem to judge the properties of single loop interactions has been given; the study also indicated that the properties of interactions cann't independent of the properties of subsystems in the multi-loop interaction conditions, and a all field root locus method has been proposed to decide the properties of interactions; a interaction stabilizable theorem has been given, and the efficacy of interactions with respect to the interconnected systems has been configured, Some primary results are reported which are induced by using a method of computer aided test to study block interactions, the stationary feedback efficacy of closed loop interactions have been discussed and a stability guess has been proposed.

本文提出互连系统的合作稳定性概念及其原理，给出了互连系统的本原稳定度、稳定中心、回路关连的级数以及关连的性质等基本定义；并在此基础上对线性互连系统进行关连分析，给出了一系列涉及到关连与互连系统稳定性关系的命题、引理、定理及其证明；其中，在子系统都是一维的线性定常互连系统情况，得出了单回路关连性质判断的定理；并指出在多回路关连条件下，关连的性质不能独立于子系统的性质，以及用全域根轨迹法判断关连性质的方法；给出了关连可稳定理，并对关连对互连系统的影响作用进行了分析。本文还用机辅试验的方法研究块阵关连并给出一些初步结果，本中还探讨了回路关连的静态反馈作用并提出一个判稳猜想。

本文着重讨论了线控制动系统与安全相关的控制方法和装置，其内容主要包括以下几个部分： 1、讨论了两种不同类型线控制动系统的优缺点，并选择电子机械式制动系统为研究对象，制定了线控制动系统的硬件冗余布置方案。

Among the diversity of security technologies, intrusion detection technology is one of the focuses. This thesis at first elicits the situation of nowadays intrusion detection technology and Intrusion Detection System after explaining the basic concept of intrusion detection. Then on the basis of analyzing some representative IDSs the shortcomings existing in traditional IDS are presented, such as being lack of distribute distributivity, flexibility, interoperability etc. Therefore new technologies are needed for explored to improve the overall performance of IDS.

入侵检测系统是目前网络安全领域的一个研究热点，本文首先从入侵检测的基本概念出发，阐述了入侵检测技术以及入侵检测系统的发展现状，通过分析当前一些有代表性的入侵检测系统指出了入侵检测系统存在的一些不足，在很多地方还有待改进，如分布式、灵活性、效率等方面，需要探索新的技术来提高入侵检测系统的整体性能。
