摘　　要：文中从方便学习者使用异构移动终端进行数学公式及图形查询的角度出发,设计了一种基于Web Services四层架构的移动数学公式及图形查询系统。该系统的服务端使用J2EE开发,客户端使用J2ME开发,以支持学习者通过不同分辨率、不同操作系统的移动设备查询常用公式、函数及图形,另外,该系统还使用Mobile SVG技术生成矢量数学图形,并将Ajax、gzip等技术用于提升性能,能大大提升查询速度、节省移动客户端的有效存储空间。该系统的架构和所采用的技术克服了目前移动设备访问网络资源速度较慢、存储量较小、分辨率不同等各种影响学习效果的不利因素,因此能为学习者提供更好的移动数学学习支持,具有很好的应用价值。In order to bring the convenience for learners querying mathematical formula and graphics, a mobile mathematical formula ＆ graphics query system based on four-tier structure Web Services was designed to facilitate query in heterogeneous mobile terminals. J2EE was used to develop the server-side and J2ME used to develop the clients-side in this system,which can help learners to inquire mathe- matical formulas, functions and graphics through heterogeneous mobile devices efficiently. Moreover,Mobile SVG was used in this system for creating vector graphics,and Ajax ＆ gzip were used for promoting query speed and saving mobile devices memory. The structure and technology applied overcome the negative factors influence learning efficiency in existing devices with low speed of accessing network re- source, small memory,different resolution, so provide better mobile mathematical learning support for learners, has great application value.
