说明：  利用哈夫曼编码进行信息通讯可以大大提高信道利用率，缩短信息传输时间，降低传输成本。为信息收发站写一个哈夫曼码的编译码系统，要求在发送端通过一个编码系统对待传数据预先编码；在接收端将传来的数据进行译码(复原)。对于双工信道 (即可以双向传输信息的信道)，每端都需要一个完整的编/译码系统。
(The use of Huffman coding can greatly improve the information communication channel utilization, reduce the information transmission time, lower transmission costs. As the information transmitting and receiving stations to write a Huffman coding system, requires the sending end through a coding system for pre encoded data at the receiving end of data the decoding (Fu Yuan). For duplex channel (which can be a two-way channel to transmit information), each side is required for a complete encoding/decoding system.)
