说明：  4. 试说明卷积编解码的工作原理： (1) 使用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。 (2) 请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4. Try to explain the working principle of convolutional codec: (1) Simulink was used to simulate convolutional coding, and Viterbi decoding method was used for decoding. The coding and decoding were all written by oneself (s-function method), rather than calling the existing coding and decoding functions of Simulink. (2) in the additive white gaussian noise channel, please draw the curve of the relationship between bit signal-to-noise ratio and bit error rate.)

说明：  matlab程序，计算三角形单元变形受力，可绘制应力云图，位移云图(Calculation of deformation and stress of beam element)

二维TM偏振平面波传播演进的FDTD实现。(Two-dimensional plane-wave propagation in the evolution of FDTD implementation)

说明：   仿windows文件管理器 ，有多标签，你可以打开海量标签，不拥挤，不杂乱，有强大而细致的标签管理，真正实现单窗口操作，多窗口切换，功能上windows该有的都有，没有的也有，比windows只强不弱，你会离不开它，有delphi7源代码。 本程序已实现了 ShellTreeView 和 ShellListView 所有用法，包括 排序，显示隐藏文件，显示扩展名，过滤，右键粘贴，等原先没有的功能，是极佳的参考资料，你可以轻易修改我的程序，创建自己的文件管理器。(Like windows file manager, a number of labels, you can open the mass label, not crowded, not cluttered, with a strong and detailed labeling regulations, the real single-window operation, multi-window switch function of the windows and some have not There are also more than just strong not weak windows, you can not do without it, there delphi7 source code. This procedure has been achieved and ShellTreeView all ShellListView usage, including sequencing, Show hidden files, show extensions, filters, right-paste, etc. is not the function of the original, is an excellent reference, you can easily modify my program to create its own File Manager.)

VB6.0实现的FLASH导航传递。。和调用(FLASH navigation VB6.0 achieved transmission)

校园网中的计算机使用一块网卡就可以实现校园网与外网无缝切换-Campus network using a computer network card can be achieved outside the campus network with seamless network switching

说明：  rs编解码，对实现了rs码的编解码，并对其误码率进行了分析仿真(rs codec, to the achievement of the rs code coding and decoding, and BER analysis simulation)

DFMirage镜像驱动的二进制安装包，可以进行后台安装和卸载；通过这个镜像驱动可以提供截屏的效率(The binary installation package of DFMirage image driver can be installed and uninstalled in the background; the efficiency of screenshots can be provided by this image driver.)

hack for crossfire old source codes

小型虚拟机，可用于汇编模拟，效果还可以！！！！！！！！(Small virtual machine, can be used for assembly simulation, the effect is also ok!!!!!!!!)
