| 摘 要： | 随着通信技术的迅猛发展,如何构建一个有效的通信系统,以尽量少的符号传递尽量多的信息,即提高通信系统传递信息的有效性,是通信技术的关键技术,而信息率失真函数是构建通信模型中的一个非常重要的指标,利用正、反试验信道对率失真函数进行了分析,从而展示出反向试验信道的分析优势,为在通信中能正确理解和熟练掌握信息率失真函数有重要的作用,尤其为建立合适的通信模型并解决通信中的编码问题奠定了坚实的理论基础。

| Abstract: | How does an effective communication is built with growth of communication technology,it can transmit more information by less symbol,which is the effective communication and sky technology on communication,and distortion function of information rate is an important target in communication model.The paper discusses distortion function of information rate by both of right and oppose trial information road,this appoints out good way on oppose trial information road and plays an important affection for understanding correctly and grasping skillfully distortion function of information rate in communication,especially,which has established solid theory basis for coding and model in the communication. |

| Keywords: | distortion function of information rate distortion degree trial information road information theory |
