一个实用的房地产行业收费管理软件，在DELPHI下编译运行。

CLX Diagram You can always use conversion functions to register a conversion unit. There are times, however, when this requires you to create an unnecessarily large number of functions that all do essentially the same thing.

Ultra-precision 1:4 LVDS Fanout Differential Translator with internal termination

操作系统实验，进程同步与互斥读者写者问题，用vc实现-experimental operating system, and coordinate the process of the readers who wrote, using vc achieve

同时如果在移动端运行的话，也支持触屏滑动来切换图片(At the same time, if the mobile side is running, it also supports touch screen sliding to switch pictures.)

利于MATLAB实现OFDM的发送和接收，具体过程发送端先通过QPSK调制，之后进行IFFT变换，然后再添加循环前缀，接收端是一个逆过程。该程序还有另外一个的功能是信道估计，最小乘与卡尔曼滤波器的比较。(MATLAB is helpful to realize the sending and receiving of OFDM. The sending end of the specific process is firstly modulated by QPSK, followed by IFFT transformation, and then cyclic prefix is added. The receiving end is an inverse process. Another function of the program is channel estimation, least - multiplication and kalman filter comparison.)

DC-DC变换器的双有源桥DAB拓扑的MATLAB仿真，开环仿真(MATLAB simulation of dual active bridge DAB)

VC++ 模拟实现网络语音电话，类似语音聊天的功能，这是一个通过网络实现的网络语音电话，功能目前是比较基础的，仅供学习参考吧。本实例当时在Windows 2000环境下运行通过。相关的代码如下： 　　#define BUFFERSIZE 5120 //缓冲区大小 　　static HWAVEIN hWaveIn ; //录音设备句柄 　　static HWAVEOUT hWaveOut ; //播放设备句柄 　　static PBYTE pBufferIn[2]; //用于接收和播放的两块缓冲区 　　static PBYTE pBufferOut[2]; //用于发送和录音的两块缓冲区 　　static PWAVEHDR pWHIn[2]; //用于录音的PWAVEHDR结构数组 　　static PWAVEHDR pWHOut[2]; //用于播放的PWAVEHDR结构数组 　　static WAVEFORMATEX waveform ; //用于打开音频设备的WAVEFORMATEX结构 　　int nIn = 0; //当前播放缓冲区号 　　int nOut = 0; //当前录音缓冲区号 　　int nComState = 1; //显示通话状态信息的变量 　　CString LocalIP; //本机IP地址 　　CString RemoteIP; //远端主机IP地址 　　CServerAS sServer; //服务器套接字 　　CClientAS sClient; //客户端套接字 　　CServerAS sListen; //监听套接字 　　BOOL ConnectDown = FALSE; //“连接”按钮是否被按下 　　BOOL sState = FALSE; //是否处于服务器端状态 　　BOOL cState = FALSE; //是否处于客户端状态
