介绍了一个模块自动封装工具ME，它是通用的交互式可视化环境GIVE系统中的一个相对独立的部分。该系统提供了一个模块级编程环境，支持用户通过“搭积木”式的方法，从模块库中选取合适的模块，构建可视化流图。模块库的内容决定了系统的应用领域。ME基于一套API库函数和模块的语法定义，通过可视的操作界面，支持用户直观交互地将自己开发的算法扩充到系统的模块库中，使系统具有良好的开放性，能适用于不同的应用领域。

This paper presents an automatic module wrapping tool,Module Extender(ME).ME is a relatively independent part of the General Interactive Visualization Environment(GIVE).GIVE provides a convenient module-level programming environment.And it supports users to set up a visualization map by selecting appropriate modules from the Module Librarian.Thus,the contents of the Module Librarian decide the system's application fields.By the visual operative interface ,ME supports users to directly build modules from existing algorithm codes into the Module Librarian on the basis of the API functions and the module's syntactical definition.This makes the system an opened environment and adaptable to different application fields.
