Introducing 9 english medical search engines and some chinese and english medical databases ( at this time there are no chinese medical search engines ) ; comparing and analyzing medical search engines in the scope of information , costs , if keyword or classification retrieval is provided and / or whether web site grading is provided . chapter three : chapter 3 discusses another way to search the internet - chinese common search engines 介绍internet上较为常用的9种英文医学搜索引擎(目前尚无中文医学搜索引擎) ，并对每一种医学搜索引擎的信息收录范围、检索功能、网站质量等方面进行对比分析：介绍internet上有影响的、常用的中英文医学数据库，对每一种数据库的收录文献侧重范围、提供的检索途径、收费情况等进行对比分析。
The system stores spatial data and characteristic data into central database , and provides services to users in server / client mode . as the research emphases of this thesis , several key sub - systems are designed and realized . the digital map input and maintenance subsystem performs format conversion , editing and updating of spatial data ; the rail - track video playing subsystem uses video recording as reference data , then plays , inquires and traces the corresponding frames in synchronous to the scaled mileage , realizing the query of the active picture frames ; the digital map query subsystem fulfills the map query , preview and spelling of digital map orthograph 其中，地形图输入与维护实现了数字地图的格式转换、编辑处理以及空间数据的更新操作，解决了不同格式空间数据的互相转换问题；线路录象播放将线路录像数据作为系统的一种索引数据，活动影像的画面与里程相对应，实现了基于线路录像的播放、查询和检索的功能，实现了基于活动画面的查询检索功能；数字地图子系统完成了图形查询、数字地图与线路正射图像浏览、图幅拼接等功能。
First of all , non - linear retrieval technique is introduced to put forward the system function model , in the light of characteristics of expressway monitoring . moreover , the proper index file structure is designed to make it more suitable for computer to deal with . finally , the net protocol is defined to realized the non - linear retrueval of remote video files 首先，针对高速公路管理过程中事件的突发性和监控系统图像检索的高频率和时段性的特点，将非线性检索技术引入到系统中，提出了具有非线性检索功能的系统模型。其次，根据模型设计出适合计算机处理的检索文件的文件结构。
