Byte error correcting codes are demanded in byte-oriented systems such as main memory, data transfer path, etc.. In this paper a class of single byte error correcting double byte error detecting codes (Sb/EC Db/ED codes) generated by means of the recursive process is presented. If the byte length is b, the length of checking part of the code is m bytes, the length of information part of the code is k bytes, then the maximal code length will be n=m+k=2m-2 (2b-1+1) bytes. In case of b= 1, these codes are...

Byte error correcting codes are demanded in byte-oriented systems such as main memory, data transfer path, etc.. In this paper a class of single byte error correcting double byte error detecting codes (Sb/EC Db/ED codes) generated by means of the recursive process is presented. If the byte length is b, the length of checking part of the code is m bytes, the length of information part of the code is k bytes, then the maximal code length will be n=m+k=2m-2 (2b-1+1) bytes. In case of b= 1, these codes are the same with the ordinary binary Hamming SBC DED codes. Furthermore, another class of Sb/EC Db/BD rotation codes is produced with a computer. The length of such a code is longer than that of the previous one as the length of the checking part is increased.

对于面向字节组织的系统,如存储器、数据传输通路等,为了提高系统可靠性,需要采用能校正字节错的纠错码。本文提出一种用递归方法形成的单字节错校正双字节错检测码(S_bEC/D_bED码)。设字节长度为b位,该代码的校验部分长度为m字节,信息部分长度为k字节,则最大代码长度为n=2~(m-2)(2~(b-1)+1)字节。在b=1的特殊情况下,即为一般二元海明SEC/DED码。此外,用计算机推导出一种S_bEC/D_bED旋转码,这种码随校验部分长度的增加,具有比前一种码更大的代码长度。

CUSAS-82 Structural analysis program system is a program system which is Suited to the conditions of our country. It has a great many of functions and may be used for static and dynamic analysis of the continued and complex structure. The advanced method and technique of the domestic and foreign have been used and developed in this program system. Therefore, it not only be used conveniently and flexibly, but may be transplanted easily as well. And it is aimed at. The prepared work before the calculation on the computer is little and the calculation efficiency is higher. So there is a good economy beneficial result. This system had been installed EC-1022B electronic computer of our university and begin to serve the economic construction of our country and was used for productive problems of the some trades, such as crane machinery, automobile manufacture and heavy-duty machine.

CUSAS-82结构分析程序系统是一个适合我国国情的,具有多种功能的,用于求解连续体结构和复杂的组合结构的静力和动力分析的程序系统。在研制该程序系统时,应用和发展了国内外先进的研制软件的方法和技术,它使用方便灵活,易于移植,针对性较强,上机前的准备工作量较少,解算效率较高,有较良好的经济效益。这个程序系统已装入我校计算中心EC-1022B电子计算机,开始为国民经济建设服务,已被用于起重机械、汽车制造、重型机械一些行业中的生产实际问题。

In this paper, a class of codes capable of correcting t errors anddetecting multiple unidirectional errors (t EC-MUED code) is discussed. It is proved that a systematic tEC-MUED code with k information bits requires at least [(t +1)log2k-log2((t + 1)1)]-1 check bits. A class of systematic 2EC-MUED code requiring at most [6 log2k + log2 log2 k + 1] check bits is also given. Finally a conjecture about tEC-MUED code is developed.
