论文部分内容阅读
近年来我曾在《机械工程》杂志上介绍过机械工程界常用的几种检索刊物。这对于机械工程师掌握查找文献的基本技能无疑会有帮助。但是有时还需要通过国际联机检索来查找文献,特别是在申请专利和成果鉴定需附查新证明时,必须这样。科研项目立项、开题报告、科研攻关资料搜集、国际市场调查等和大学机械工程各专业指导研究生毕业论文,有时也
In recent years, I have introduced several search publications commonly used in mechanical engineering in Mechanical Engineering magazine. This will undoubtedly help the mechanical engineer master the basic skills of finding documents. However, it is sometimes necessary to search the literature through international online search, especially when applying for a patent and the identification of the result needs to be accompanied by a new certificate. Scientific research project project, the opening of the report, the collection of scientific research materials, international market research and mechanical engineering, professional guidance graduate thesis, and sometimes
