Our system is supported by a strong background multimedia database and has several characteristic query methods . it integrates various of dynamic query technologies of the single - condition query , multi - condition combination query , directory tree navigating query , and with a individual material database for every user . background multimedia material database can self - expanded during interactive operating with web users time after time 后台多媒体素材数据库能很好的支持各种媒体信息(如文本、图像、音频及视频等)的管理维护，而且通过前台网页与用户的交流可以不断地扩充多媒体素材数据库信息，建立一个更加完善的面向高校教学育人的网站。
Users can edit the word , graphic , picture , voice , animation and movie together , and also can edit formula , the system realizes the mixed arrange of word and picture , and text - to - speech . this article emphasizes on the technologies in my research and some relative theories , and also points out the direction of the further work 通过系统软件，用户可以把文字、图形、图像、声音、动画及影像等多媒体素材集成编辑，还可以编辑公式，实现图文混排、语音跟读等功能，在课题中还提出了题库设计、组卷、测试、评卷的具体解决方法。
It describes the instruction procedure with computer programs , in the meantime , using the key techenology of multimedia interactivity , hyper text and ole ( object linking and embedding ) the base of the instrument analysis instructional software is according to teaching book of analytical chemistry ( 4th version , edited by yuqing sun ) , including basic theory , brief summary ? exercises , and experiment 多媒体即多种信息的载体如数字、文字、声音、图形、图像、动画等。多媒体教学软件的开发属于计算机辅助教学( cai : computerassistedinstruction )的一部分，计算机辅助教学就是把教学过程用计算机程序进行描述，同时，引入多媒体素材的集成与交互控制、超文本链接方式、嵌入与链接等关键技术。
With a reference of others " work , he designs a set of chinese language segmentation and categorization algorithm without the support of dictionaries . thus he develops an automatic text classification software and suggests further solutions to problems such as how to apply this technology to a multimedia database , and realize the media search based on contexts not keywords . with that , the author gives the main plan and overall design of his software 在前人研究成果上，予以创新，设计了一套无需词典支持、简单易行的中文分词和分类算法，开发了“文档自动分类软件” ，并对如何将这一技术与多媒体素材库相结合，实现对媒体素材的模糊查询和智能分类等问题进行了探讨，给出了软件设计的总思路和总方案。
