摘　　要：本文在三值汉明码一位检错纠错研究工作的基础上,对三值汉明码的检错纠错方法进行进一步研究.给出了扩展三值汉明码的形式,通过对扩展三值汉明码的错误分析获得了一位纠错和二位检错原理,给出了扩展三值汉明码的纠错码表,根据纠错码表提出了一位纠错方法,给出了基于三值光学计算机的扩展三值汉明码检错纠错概念结构图和功能部件,为检错纠错系统的光学设计提供一种途径.In this paper,on the basis of research of 1-bit detecting-correcting for ternary Hamming code,further research is carried out.With the form of extended ternary Hamming code proposed,the principle of Single Error Correction and Double Error Detection is proposed by analysis of the error in extended ternary Hamming code.By the two error-correcting tables presented the method of error correction of ternary Hamming code is obtained.Then the graph of error detection and correction conceptual structure of extended ternary Hamming code and its functional components are put forward in the ternary optical computer.The work provides a new approach for the design of detecting and correcting system optically.
