实用的二维动力射线追踪软件seis88最新版本，就是输入格式有点麻烦。非常适合模型正演。-Practical ray tracing of two-dimensional dynamic seis88 the latest version of software is a bit cumbersome input format. Very suitable for forward modeling.

电力系统故障点matlab仿真，用于故障点稳态分析(very good)

VC++顶层窗口 置顶窗口源代码，显示在最顶层的窗口，当启用本功能后，所有打开的窗口都要置于本窗口的下层，也就是本窗口始终不会被遮挡。目前已经有不少的软件，使用有这种效果，类似视频播放器程序在播放视频时，总是将播放窗口显示在最前端。

这是一个弹球的游戏，不过有些粗糙。基本功能还是可以的-This is a pinball game, but some rough. Basic functions can still be the
