通信性

To improve the performance of security,periodicity and equality,a finite precision chaotic sequence generator was designed based on the structure of digital filters.

为了提高数字通信系统中产生序列的保密性、周期性和均匀性，设计了一种有限精度非线性数字滤波器结构的混沌序列发生器。

The innovation of model is adopting mobile agent to replace RFC and OORPC to implement the connect and communication between the client and server, in this way, it can remove the disadvantage of the traditional middleware and add the intelligence, flexility and adaption to the network to the communication between the client and server.

其创新之处在于，此模型采用移动Agent取代传统的RPC和对象RPC机制实现客户与服务器的智能连接，从而解决传统中间件的不足。使得客户端和服务器间的连接和通信具有智能性，灵活性和良好的网络适应性。

Using the uniform information channels and the technology of SOAP and COM/DCOM/COM+, information integration among tool management system, ERP/MRPII, CAM and CAPP system is come true. Finally, the distributed tool management system is developed in using mutil-tired Client/Server model as the frame of software. It has the functions of tool general management, searching milling cutting data for CAM by providing the milling cutting data e-book and computer aided tool selection for CAPP by using expert system. The tool management system offers the tool-coding function, too. The study of tool management system in DNC improves the level of tool management and the flexible of arranging production, haleness and the automatic extent of DNC systems.

依托DNC系统统一的、强大的通信平台和采用SOAP、COM／DCOM／COM~+信息集成技术，实现了刀具管理系统和上层管理系统ERP／MRPⅡ、CAD／CAM／CAPP系统、下层数控加工设备之间的信息集成，并采用三层Client／Server软件体系架构开发了相应的分布式刀具管理系统，实现了刀具的日常管理和调度功能，并建立了一套适合DNC系统使用的刀具编码原则和刀具辅助编码系统，应用铣削用量电子手册为CAM提供铣削用量查询功能和运用知识库系统为CAPP提供简易的粗铣加工使用的铣刀类型和刀具材料辅助选取功能，提高了DNC中刀具及相关信息的管理水平和刀具信息集成程度，达到实现DNC系统中刀具信息共享，提高DNC系统的生产组织柔性、健壮性及其自动化程度的目的。

It is a hard work and many heuristic algorithms are proposed.

因此，研究高效的通信协议是提高传感器网络节能性的关键。

Decision fusion is extensively used in multi-sensor data processing because of its merits, such as few communication data, strong fault-tolerant and low request for homogenesis of sensors.

决策融合因其通信量小、容错能力强、对传感器同质性要求低等优点而被广泛地应用于多传感器数据处理。

But these LANs have the inherent disadvantage that cause the indeterminable waiting time for the data frames, so they can not be directly applied to communication networks with high timing requirement.

但是这些局域网的介质访问控制协议先天具有着令数据帧等待时间不确定等缺点，所以不适合直接应用在对实时性具有要求的通信中。

There were occasional problems with interference and reliability, but on the whole, these provided an indispensable means of communication.

有间歇性的问题与干扰性和可靠性，但就整体而言，这些提供了一个不可或缺的通信手段。

This system not Only realizes real-time communication and interoperability, but also has high reliability and high portability.

该系统不仅实现了信号的实时通信和互操作，而且具有很高的可靠性和可移植性。

To compare communication link importance in communication networks invulnerability,a algorithm based on link-contraction is proposed.

为了比较通信链路在通信网抗毁性中的重要性，提出了一种基于链路收缩的算法。

In chapter 2, basic knowledge of graph theory and communication correlation to invulnerability on topological structure of RCN is introduced.

文章第二章，介绍了与野战地域通信网拓扑层抗毁性相关的图论及通信基础知识。
