说明：  利用4个公共点解WGS84转北京54的7参数(The use of public four-point solution to WGS84 parameters Beijing 54 7)

说明：  在基于脉冲的UWB系统中，采用瑞克接收机合并多径信号能量并进行相干检测，信道估计问题即估计多径信号的到达时间和幅度。在基于OFDM的UWB系统中，接收机根据信道频域响应对每个子信道进行频域均衡后进行相干检测，信道估计问题即估计信道频域响应。(Pulse-based UWB systems, rake receivers using the combined multipath signal energy and coherent detection, channel estimation problem that is estimated multipath signal arrival time and amplitude. OFDM-based UWB system, the receiver under the channel frequency response of each subchannel to frequency domain equalization after coherent detection, channel estimation problem that is estimated channel frequency response.)

一个简单的OPENGL程序,关于MENU的显示，点击鼠标右键，显示SUBMENU(A simple program in Opengl.)

说明：  Bacom use mmc not test very fast

帐户管理系统，可以删除，添加修改，查询等功能，还可连续创建帐户。(Account management system, you can delete, add modify, query and other functions, but also continuously create an account.)

C语言是一种计算机程序设计语言,它既具有高级语言的特点,又具有汇编语言的特点。它的功能性非常强大,目前是各高校的一门必修课。并且市场上许多软件也是基于C语言的平台而产生的,所以C语言在大学中的教学也称得上是"不遗余力"。但是近些年很多的学生普遍反映C语言晦涩难懂,不容易学透,非常努力的学最后却得不能心满意足,课程过后一无所获,甚至一个小小的程序都写不出来,于是针对这些情况就做出一些初步的分析,并且从C语言编程技巧上提出相关的改善对策。 (C language is a computer programming language, both with advanced language features, but also has characteristics of assembly language. Its function is very powerful, is now a required course in colleges and universities. And also a lot of software on the market based on the C language, platform and produce, so C language teaching at the university is also described as a "spare no effort." But in recent years, a lot of students generally reflect the C language obscure, not easy to learn thoroughly, very hard to learn, but finally could not have satisfied the course after nothing, even a small program that can not write, so for these situations to to make some preliminary analysis, and from the C programming language skills relevant improvement measures put forward.)
