设计论文题目：

CHM 格式分析及优化

摘要

随着信息技术的发展，个人计算机越来越普及。人们也越来越多的利用计

算机方便自己的生活。人们在计算机上阅读的需求也日益增长。其中  就

是一种非常普及广泛的电子书籍格式。另一方面，随着个人掌上电脑，智能手

机的发展，人们也花费更多的时间阅读电子书籍。但移动设备的处理能力离 

尚有较大的差距，因此如何快速有效的解析  格式电子书籍是移动设备上

湖南大学毕业论文第 II 页

阅读软件的需求。

本课题研究的目的在于为  和移动设备平台提供  电子书籍的解析功

能。在充分分析  格式规范的基础上，比较各种主流解析  方法，在

 阅读器性能方面进行优化分析和处理。

难点：该课题主要的难点在于如何分析 CHM 的格式的各个部分,特别是在

无微软官方格式说明的情况下。如何兼容各种版本的 CHM 格式文件也是一项

艰巨的任务。同时，对应于手机移动设备的特殊硬件条件，如何使程序占用极

少的内存的同时以快速的方式解析文件，为用户提供流畅的阅读体验是本课题

的重点。

关键词：，手机移动设备，解析
