观察自然频率对振动模态的影响（固定阻尼系数），可对有强迫振动项 的情形进行观察，将阻尼系数和自然频率固定，选择一种 的形式，观察 对振动模态的影响。 2、对由方程刻画的单自由度阻尼系统做动画仿真，观察阻尼系数，固有频率以及强迫振动项 对弹簧振动的影响，并和振动曲线图进行对比，写出你的观察结论。 -1、To observe the natural frequency of the vibration mode of (fixed damping coefficient), may have forced vibration of items to observe the situation, the damping coefficient and natural frequency is fixed, choose a form of observation of the impact of vibration mode. 2, characterized by the equation of a single degree of freedom to do animated simulation of damping system to observe the damping coefficient, natural frequency and vibration forced vibration of the impact of spring items, and to compare and vibration curve, write your observations conclusions.

通过MATLAB对过采样sigma-delta调制器进行仿真的设计方案，采用多级级联结构，有效减少运算量和硬件开销。-By MATLAB on the over-sampling sigma-delta modulator design simulation, using multi-stage cascade structure, effectively reduce the computational complexity and hardware overhead.

此为一种新型的电子城的设计方案 绝对好用啊-This is a new type of electronic design of the city is absolutely easy to use ah

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。
