这是一个利用哈夫曼进行压缩和解压缩的程序。这不是初学时的一个黑洞洞的用键盘慢慢输入的控制台。这是一个用鼠标操作的程序；而且它在打开和退出时均有窗口动画。在操作时会有窗口抖动和警告音提示。-This is a use of Huffman compression and decompression procedures. This is not a beginner when a dark, slowly entered with the keyboard console. This is a program using the mouse　and it is both open and exit the window animation. Will be in operation when the window jitter and warning tone prompts.
