要 高性能和安全是计算机网络研究的两个主要问题。如何使路由器在保证转发性能的前提下提供网络安全保护已经成为当前的研究热点。本文介绍了在完成国家“863”计划重大课题“高性能安全路由器”的过程中解决的若干关键技术问题。“高性能安全路由器”基于自主设计的高性能路由器操作系统HEROS。为保证高性能的路由转发，设计实现了基于RAM的高性能路由查找算法；为支持服务质量控制和安全管理，设计实现了基于无冲突哈希Trie树的分组分类算法和基于反馈的分布式分组调度算法；为保证网络安全，提出了基于分布式密钥管理的路由器安全体系结构。

给出了沉浸式虚拟维修仿真系统的框架，从样机建模和交互技术两个方面对其关键技术进行了研究．提出 了虚拟维修样机的概念，通过定义样机部件的约束运动和交互特征来实现其所要求功能，而交互技术则主要集中在 抓取和防穿越处理上．建立了基于Jack系统的沉浸式虚拟维修仿真原型系统，并以某机构的拆装为例对其进行了初 步的应用验证-Give the Immersive Virtual Maintenance Simulation System framework, from prototype modeling and interactive technology for its two key technology areas were studied. Put forward the concept of a virtual prototype of repair, by the definition of prototype components bound to exercise and interactive features of implementation of its functional requirements, and the interactive technology was mainly concentrated in the crawl up and deal with anti-crossing. Jack set up a system based on Immersive Virtual Maintenance Simulation prototype system and the dismantling of an institution as an example of its application for a preliminary verification

摘要:基于通信技术的列车运行控制系统(CBTC)是铁路信号的发展方向，交频分复用 OFDM)是一种无线环境下的高速传输技术，它对高速列车控制信息传输中卞要受到的由于多 径传播引起的快衰落所产生的影响有很强的抵抗能力.本文首先介绍了OFDM技术的发展和 基本原理，然后在计算机上用M atlal〕对其性能进行了仿真，仿真中将OFDM与传统的单载波 调制方式―i1，交振幅调制( 1frQAM)对抗多径十扰的性能进行了比较，最后分析了一者的仿真结果. -Abstract: Based on the communication technology train operation control system (CBTC) is a railway signal direction for the development of cross-frequency division multiplexing OFDM) is a wireless environment of high-speed transmission technology, its high-speed train control information transmission Bian be subject to the Due to the spread of multi-path fast fading caused by the impact of a strong resistance to diseases. This paper first introduces the OFDM technology development and the basic principles, and then on the computer〕 M atlal use its performance simulation will OFDM with the traditional single-carrier modulation-i1, cross-amplitude modulation (1frQAM) against multi-path interference of the 10 properties were compared with a final analysis of
