从第一章到第六章,对文献库与计算机检索问题作了比较全面的论述。在此基础上,我们有可能对检索技术的一些难点作进一步的探讨,目的在于尽可能少地利用机时而获得最满意的效果。众所周知,计算机处理是以秒计费的,这是事实上的时间等于金钱。所以文献库的质量和检索技术都直接地影响到检出效果的经济性。 From the first chapter to the sixth chapter, we make a more comprehensive discussion on the issues of document library and computer retrieval. On this basis, we may further explore some of the difficulties of the search technology with the aim of obtaining the most satisfactory results using the machine time as little as possible. As we all know, computer processing is billed in seconds, which is the fact that time is equal to money. Therefore, the quality of the literature library and retrieval techniques have a direct impact on the economy of detection.
