VC++学生信息管理系统
1. 去掉“只读”属性。
2. 在SQL Server2000中，附加数据库UGMS。
3. 编译不受源文件位置和数据库位置的影响。即，HMS的整个工程复制到任何地方都可编译。-VC++ Student Information Management System 1. Remove the " Read Only" attribute. 2. In SQL Server2000, the additional database UGMS. 3. Compiled from the source file location and database location of impact. Namely, HMS copy of the entire project can be compiled anywhere.

您可能已经设计了数据库，以及表
或许大家都设计过数据库,也为表定义过主键,今天我想阐述的是,应该如何正确的设计一个主键,在以往的一些资料中,都没有提及到主键设计的原则.我为此总结了一下:
-you might have designed the database, as well as table-defined primary key, and today I would like to explain is that How should correct the design of a primary key, in the past some of the information. no mention of the primary key design principle. I summarize this for a moment :

本文首先概述了OFDM 的原理、特征和关键技术，介绍了系统需要的几种同步。然后就同步误差对系统性能的影响进行了简单的分析，表明定时偏差和采样频率偏差将会引入码间干扰，载波频率偏差导致载波间干扰的发生。因此，在OFDM系统接收机中定时的确定、载波频率偏差和采样频率偏差的纠正是信号恢复的关键。之后对OFDM系统同步的几种实现方法进行了介绍，分析了各同步方法的性能。-The paper first outlines the principles of OFDM, features and key technologies, the system needs to introduce several synchronization. Synchronization error and then the impact on system performance for a simple analysis, show that the timing deviation and the sampling frequency deviation will introduce inter-symbol interference, the carrier frequency deviation led to the occurrence of ICI. Therefore, in OFDM system receiver to determine the timing, carrier frequency offset and sampling frequency offset correction signal to restore the key. After the OFDM system to achieve synchronization of several methods of introduction, an analysis of the performance of the synchronization method.
