论文部分内容阅读
文献检索一般来说是指从主题、个人作者、团体作者,刊名、语种、出版年月等多种角度查找文献。一个从事新课题研究的科技人员在开展科研工作时,应了解迄今为止前人已完成哪些工作、国内外同行的水平如何以及正在搞哪些课题,已发表的哪些资料可借鉴等等,即所谓“科研工作,情报先行”。而一个专利权申请者,在提出申请前,必须查明他要申请的专利是否同已发表的专利重复。因此,科技文献检索是科研人员必备的一种能力。
Document retrieval in general refers to the literature from a variety of perspectives, such as topics, individual authors, group authors, titles, languages, years of publication. When undertaking scientific research, a scientific and technical personnel engaged in the research of a new topic should understand what the predecessors have done so far, the level of their counterparts at home and abroad, what issues they are engaging in, what information has been published, and so on. The so-called “Scientific research, intelligence first”. A patent applicant, before filing an application, must find out whether the patent he is applying for is duplicated with the published patent. Therefore, scientific and technological literature retrieval is an essential ability of researchers.
