认为医学科技查新与一般文献检索有显著区别,医学科技查新虽然离不开检索,但查新工作有较严格的年限、范围和程序规定,有查全、查准,尤其是查准的严格要求,查新结论具有鉴证性。透彻地理解和把握课题项目的关键内容,准确地分解查新要点和专利申报查新要点至关重要。 It is considered that there is a significant difference between the search of medical science and technology and the retrieval of general documents. Although the search of new medical technology can not be separated from the search, the work of searching for new medical records has more stringent years, scopes and procedures. Strict requirements, check the new conclusions of the authenticity. It is very important to thoroughly understand and grasp the key contents of the project and to accurately decompose the key points of investigation and new points of patent application.
