前言科学技术发展很快,科技文献资料的数量急剧增大,科技情报工作就越加重要,因为不学习先进成果就会落后,不掌握情报资料就会白费时间,而检索手段的落后使很多宝贵的科技资料不能很好发挥作用,为了查找有用的资料,往往要花很多时间,有些课题查找资料占到科研时间的1/4,乃至1/3。如何加速提供科技情报,是情报工作现代化的关键。利用电子计算机能够快速地、准确地、方便地完成情报资料检索。
Foreword Science and technology are developing very rapidly. The number of scientific and technical documents is drastically increased. Scientific and technological intelligence work is even more and more important because it lags behind without learning advanced achievements and is time-consuming without obtaining information. The backwardness of retrieval means makes a lot of valuable Of the scientific and technical information can not play a good role, in order to find useful information, often spend a lot of time, some research data to account for the research time 1/4, or even 1 / How to speed up the provision of scientific and technological information is the key to the modernization of intelligence work. The use of electronic computers can quickly, accurately and easily complete information retrieval.
