一本文是《电传打字电报机电码的编制方法及其缺陷》一文(见本刊1964年1月创刊号)的续篇.前已指出:为了传送十个数字,电码只要有四个码位就足够了,现用的五位电码可以多出一个码位作查对之用.因此如果把代码重新分配,就能对十个数字起检查错误的作用.建议采用的“三正二负电码”就是一种代码分配方案.所谓“三正二负电码”是代码的 A paper is a sequel to the “Methodology and its Defects in the Preparation and Characterization of Teletype Telegraph and Telephone Codes” (see our first issue, January 1964). It was previously stated that in order to transmit ten digits, it would be sufficient if the code had four digits Now, the current five-digit code can be used for more than one code to check the use of. So if you re-distribution of the code, you can check the wrong ten numbers from the role of the proposed use of “three positive two negative code” Is a code distribution program. The so-called “three positive and two negative code” is the code
