李白诗歌深受屈《骚》的影响，故有许多相同相似处；既表现在词语，诗句，篇章诸层面，又表面 思想内容与艺术手法层面。这是因为李白诗祖《风》，《骚》，特别是后者，李白与屈原有着相近的政治思想，相似的人生遭遇，更有着相同的耿介不阿的个性和诗人的气质，所以屈原与李白都写出了现实主义和浪漫主义完善结合的不朽诗作。 相似文献

��[Purpose/significance] Patent is one of the most reliable sources of technical intelligence. By patent analysis, one can realize the mining and the utilization of patent information, and the technology innovation. Technological evolution analysis refers to the process of emergence, development, transfer, change and even annihilation of technology themes. The focus of the current research is to deeply reveal the patent technology information, technical elements are the key to deeply reveal patent technology information.[Method/process] Proposing a method for identifying technical elements based on patent documents for specific fields by analyzing typical patents and feature recognition.[Result/conclusion] Applying our methods to the nano fertilizer field, through the analysis of typical patents, five technical elements are identified:materials, products, methods, functions and usage, and the identification of technical elements is completed based on SAO structure and domain vocabulary. Our methods can serve as a foundation for technological evolution analysis, and display field technical information from multiple perspectives. 相似文献

为精准识别技术创新机会,提出一种基于SAO语义分析与多维技术创新地图的技术创新机会识别方法。首先融合关键词分析和SAO语义分析方法剖析影响技术创新的要素,并以“链”结构梳理创新要素的层级关系,形成层次分明的技术形态；然后以多维技术创新地图为导航,基于维法耦合原理实现概念化和具象化两层技术创新机会的识别；最后以富钛料制备技术创新机会识别为例,检索并搜集392条专利为数据集。实证结果识别出3个概念化和6个具象化技术创新机会,验证了该方法的可行性,可为企业准确研判技术创新机会以不断获取技术先行者优势提供有益参考。 相似文献
