【摘要】 针对传统工程图纸查询过分依赖用户、效率低等现象，在分析可视化查询要求和待查询物体属性的基础上，提出了一种用于查询可视化模型的构造方法，并将该方法应用到工程图纸的查询中．通过工程图纸中不同图纸子库的存放地域间的层次关系，构造了基于地图模式的可视化查询系统，同时提出了地图定义和地图查询策略．更多还原

【Abstract】 In order to improve the traditional method of query for drawing, which depends excessively on users with very low speed, based on analyzing the requirements of visualized querying and the features of the object to be queried, a method to build a visualized model for query is proposed and applied to practical drawing query. Based on the stratifying relation among regions of sub data bases, a visualized query model on mapping pattern is constructed and a definition of map and map querying strategy is suggested as well.更多还原
