基于TCP协议的socket套接口编程小程序，可以在两个进程（一个客户端，一个服务器）之间收发内容，使用了epoll方式I/O复用，内容简洁易懂，是初步学习套接口编程及epoll复用的绝佳例程。

用C＋＋语言开发一个网络视频会议客户端源代码，来源不祥-C++ language to develop a video conferencing network client source code, source unknown

摘要 TCP 软件一般位于操作系统的核心，这种情况给TCP 的研究和调试带来了很大的困难。 在Sun Solaris 平台上，我们使用系统提供的DLPI 接口和有关多线程的系统调用，构建了一 个TCP 调试系统，简化了调试过程。 关键字 TCP，调试系统，DLPI，多线程-Abstract TCP software at the core of the operating system. This situation TCP research and testing has led to great difficulties. Sun Solaris platform, We use the system to provide the interface and the TCP multithreaded system calls, built a TCP debugging system, simplifies the debugging process. Keywords TCP, debugging system, Solaris, multithreading

FMCW技术和脉冲雷达技术是两种在高精度雷达测距中使用的技术。其基本原理为，发射波为高频连续波，其频率随时间按照三角波规律变化。雷达接收的回波的频率与发射的频率变化规律相同，都是三角波规律，只是有一个时间差，利用这个微小的时间差可计算出目标距离。

Very Low Frequency (VLF) spectrograms show sometimes sets of lines called MLR (Magnetospheric Line Radiation) with frequency spacing close to 50 or 60 Hz. It is very tempting to attribute these MLR to Power Line Harmonic Radiation (PLHR). PLHR are the ELF and VLF waves radiated by electric power systems at the harmonic frequencies of 50 or 60 Hz. Here we show for the first time large scale MLR observed simultaneously on ground and on board a low altitude satellite which is flying over the same zone.
