摘要:本文结合氧化还原滴定分析(对称电对反应)的学习需要，介绍了以Visual Basic环境作为开发平台，使用VB语言编写程序，开发一种主要用于计算的化学软件。

开发过程中主要采取了以下的技术路线：前期，对项目进行了详细的需求分析和综合的可行性分析，为软件的编制提供现实可行的依据；中期，根据需要整体上规划基本框架，对窗体和控件进行总体设计，详细设计了整个软件的功能实现；后期，进行系统的调试和生成可执行文件。

开发出来的本软件能够进行快速计算，用户只需按照软件的提示信息将相关的数据输入完整，软件就能自动处理数据并报告和显示相应结果，操作方便简单；还能够显示相关的知识要点和公式。而且具有友好的人机对话界面，性能良好，在WindowsXP及以上环境中均能稳定运行，比较实用，能解决复杂的计算问题，提高计算效率。

ABSTRACT:In order to meet the need of studying red-ox titration analysis(symmetric power of the reaction), the processes of authoring chemical software in the Visual Basic 6.0 was introduced in this paper.

　　The main technology of the process of the developing: The early stage of the project carried out the detailed needs analysis and comprehensive feasibility analysis. Providing realistic basic for preparing the software. In medium, according to the needs planning the basic framework. Designing for the forms and controlling in overall. Designing the whole software and realizing its function. Debugging the system and generating executable file finally.

　　The software can calculate fast. It can report and display the results automatically as long as user input the all data. Operating easily and simply. It also is able to show knowledge of relevant points and formulas. It has a friendly interactive interface and good performance. Operating stably over the WindowsXP. It is practical. It can solve complex computational problems and improve efficiency.
