摘　　要：根据对读秀学术搜索和万方知识服务平台从资源覆盖量、检索功能、结果筛选和全文获取途径的功能对比及定量定性(知识挖掘程度)分析,得出:高检全率的读秀库以广博的资源和简便的检索系统为特点在平面检索空间分布,而高检准率的万方库以优质的科技信息资源及强大的检索系统,实现库内文献间知识关联可视化成为渐进立体的多维检索空间;并为两个搜索引擎的改进和发展方向提供建议和参考。Compared the Duxiu Search with Wangfang Date from resources coverage, retrieval function, results selection, full- text obtaining ways. qualitative（ knowledge mining degree ） and quantitative analysis, the paper proposed improvement ways of two search engines and concluded that：one side encyclopedic resources with the convenient retrieval system is the core characteristic of Duxiu Search , which functional as a planar retrieval engine of high precision ratio, on the other side excellent science - technology information with the powerful retrieval system and visualized knowledge associations in literatures is the core characteristic of Wangfang Date, which functional as a progressively stereoscopic and multidimensional retrieval engine of high recall ratio.
