前言在科学技术蓬勃发展的今天,特别是在工业发达国家,人们越来越认识到传播现有技术知识的重要性,而且更加清楚地意识到这种传授必须借助于专利文献。专利文献的开辟,为使人们了解技术现状,形成、发展和实施新工艺做出了重大贡献。如果不充分利用现今的技术知识,不把它作为掌握新技术、新工艺的基础的话,我们目前和今后亟待解决的问题就不可能在较短时间内得到解决。因此,目前摆在我们面前的迫切任务是如何使专利文献服务于我们的科研工作,这就涉及到如何查找、索取并有效地利用专利文献等问题。所谓检索,即查找、索取文献的意 Preface In today’s booming science and technology, especially in industrialized countries, people are increasingly aware of the importance of disseminating existing technical knowledge, and more clearly realize that such teaching must rely on patent documents. The opening up of patent documents has made significant contributions to people’s understanding of the current state of technology and the formation, development and implementation of new processes. If we do not make full use of current technological knowledge and do not use it as a basis for mastering new technologies and new processes, we cannot solve the problems that we need to solve urgently in the short term. Therefore, the pressing task before us now is how to make patent documents serve our scientific research work. This involves issues such as how to find, obtain, and effectively use patent documents. The so-called search, that is, the meaning of finding and requesting documents
