本文介绍了一种控制普通阀门的阀门控制器的设计方案，该阀门控制器带有工业现场总线PROFIBUS－DP 的接口，可以实现阀门的远程控制和网络控制。本文主要的着力点为介绍利用PROFIBUS－DP 专用芯片SPC3 开发PROFIBUS－DP 设备中需要注意的一些问题，包括硬件接口设计，有关PROFIBUS－DP 规范标准的一些设计要点，以及利用PROFIBUS－DP 诊断功能的方法。本文对设计其它Profibus DP从站节点有很好的参考价值!-This paper presents a general valve control valve controller design program The valve controller with industrial PROFIBUS-DP interface. The valve can be achieved remote control and network control. This paper mainly focus on the use of PROFIBUS-DP SPC3 ASIC development PROFIB U.S.-DP equipment necessary to pay attention to a number of issues, including the hardware interface design, The PROFIBUS-DP standards in a number of design features, and the use PROFIBUS-DP diagnostic function method. In this paper, the design of other Profibus DP slave nodes are of value!

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.

Rapid response to traditional k
针对传统快速k-近邻分类算法的缺陷,提出了一种基于近邻搜索的快速k-近邻分类算法―――超球搜
索法。该方法通过对特征空间的预组织,使分类在以待分样本为中心的超球内进行,有效地缩小了搜索范围。
-Rapid response to traditional k-neighbors of the defect classification algorithm, a fast search based on neighbor k-neighbor classification algorithm--- Hyperspherical search. The method of the characteristics of the pre-organization of space, so in order to be classified in the sub-sample of the super-ball as the center to carry out, effectively narrowing the scope of the search.

我们要重点关注的是搜索树（search tree），并要深入探讨树结构的两个标准（tree structure），本章主要是解释二叉搜索树（binary search tree），以及下一章要讨论的AVL平衡树（AVL tree）。这两个数据中的植树是按顺序排列的，它们之间的区别在于一个平衡的AVL树，二叉搜索树都不是。
