介绍uC/OS-II 在SkyEye上的移植分析.uC/OS-II 作为一个优秀的实时操作系统已经被移植到各种体系结构的微处理器上，也是目前较为常用的公开源码的实时内核。从这里入手学习嵌入式系统开发的基本概念，以及在 SkyEye 里构造一个可以运行的RTOS，能够使我们更深入地了解嵌入式开发的流程，在没有硬件的条件下也能对ARM的体系结构有个初步的认识。-on Phone/OS-II in the transplant SkyEye analysis .uC/OS-II as a excellent real-time operating system has been transplanted to various Architecture microprocessor, It is at present more commonly used open-source real-time kernel. From here start learning embedded system development of the basic concepts SkyEye Lane and the construction of an RTOS can run, enable us to a deeper understanding of embedded development processes, In the absence of hardware conditions can also ARM Architecture is a preliminary understanding.

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

美国政府的联邦体系架构（FEA）的说明。美国政府规定所有联邦部门（federal级别)必须利用该架构描述与设计其电子政务系统。其中体现了从需求分析一直到系统技术实现的整体建模思想，提出了业务线、业务矩阵等电子政务系统分析和设计方法-the United States government of the Federal Architecture (FEA) of the note. The United States government requires all federal agencies (federal level) must be described using the structure and design of its e-government system. Reflecting the demand analysis system technology has been to achieve the overall modeling, a business line, operational matrix of e-government systems analysis and design methods
