本文着重介绍了两种计算机程序设计的技巧。其一是将CDC CYBER机用的60位字长改为30位字长,从而节约了存贮单元。实践证明,改进后的处理结果,完全可以满足地震数字处理的精度要求。其二是介绍了适用于多方面的若干快速检索(或快速寻址)方法。
This article focuses on two kinds of computer programming skills. One is to change the 60-bit word length used by the CDC CYBER machine to a 30-bit word size, thereby saving memory space. Practice has proved that the improved processing results can fully meet the seismic digital processing accuracy requirements. The second is to introduce several quick retrieval (or quick addressing) methods that are applicable to many aspects.
