摘要：现如今已经是二十一世纪，以计算机为代表的现代科学获得了蓬勃快速的发展并快速和人们的日常行为结合在一起。同时随着英语对人类的生活有着越来越大的影响，计算机信息技术的发展与进步也使电子语言词典的诞生提供了可能性。在此我设计了这个电子词典，主要实现了用户的登录和注册的功能。在初次使用该词典时，用户需要先注册一个账号，然后使用注册过的账号和密码进行登录。还有就是查询生词功能，用户通过输入一个单词，即可以查到对应的释义。在此基础之上，用户可以添加生词本，可以把任意单词添加到生词本.同时在查看完之后删除生词，用户如果认为生词本已经不需要记录某一单词，可以任意地删除已存在生词本中单词。61970

Abstract:Now is the 21st century, themodern science represented by computershas achieved the rapid development and has combined with the people's daily habits. In the meantime, the English has a more and more great influence on the human’s daily life.
