Disclaimer : i want you to understand that the numbers published here are not official in any way , but are intended to paint the overall picture so that you can get a feel for what kinds of things to expect and be able to make the right design choices while building your xml applications 声明：我想让你们理解，这里发表的数据并不是官方正式的，只是用来让你们有个全局的感觉：当建立xml应用程序时你必须考虑哪些事情，结果会怎样，应该做怎样的设计选择。
The design select the direct sequence spread spectrum technology , which resolve the problem of the signal transmission in such adverse communication circumstances as power line ; select the spectrum domain adaptive filtering technology , which has characteristics of high speed and powerful rejection for noise and interference 本设计选择采用的扩频技术为直接序列扩频技术，它解决了信号在电力线这样恶劣的通信环境中的传输问题；选择采用窄带干扰自适应抑制技术，该算法速度快、噪声和干扰抑制能力强，从而克服电力线的恶劣环境对接收信号的影响。
We choose the max _ log _ map decoding algorithm and use the technology of altera and its cyclone2 devices as the fpga design scheme according to all the factors . taking advantage of the technology of fpga , the means , called “ top - down ” and “ down - top ” , is applied in the design of fpga in this paper 在综合考虑设计方案的综合性能、复杂程度、系统规模、系统延时和成本等各项因素后,本次设计选择了altera公司的cyclone2器件来完成turbo码译码算法( max _ log _ map )在硬件语言上的仿真设计。
In chemistry engineering , the chemical equipment making enterprise have to face some problem in making the equipment after equipment ' s designing . the first problem is how to select material to make the layout , that means how can we not only guarantee the producing process but also use material economically 化工设备在完成设计后，制造企业在制造的过程中时常面临这样一些问题， 1 、如何根据设计选择合适尺寸的材料，使得材料既能保证生产的材料余量，又最大程度的降低材料的浪费。
Based on the architecture of the as / 400 server , section 3 also puts forward based develop solution of described the construction of the flight arrangement information management system develop for both of hardware platform , software platform and development tools . section 4 discussed the implementation of the applications software , in details . section 4 also particularly introduces the design and realization of the flight data input module , the flight aided arrangement module , the sold seats computation module , the important data maintain module and common forms generation module 本文首先介绍了管理信息系统的基本概念；然后分析了航班调度信息管理系统的功能需求，比较了其几种可行的实现方案，提出了以as / 400为服务器的系统总体开发方案，论述了硬件设计选择和软件总体设计和模块划分；接着，介绍了软件开发环境和工具，并对航班数据录入、航班辅助调整、销售座位数计算、重要数据维护、常用报表生成等各个软件模块的设计与实现进行了详细的介绍；最后，说明了对开发所得系统进行测试的结果以及今后改进的构想。
