摘要:本文結合氧化還原滴定分析(對稱電對反應)的學習需要，介紹了以Visual Basic環境作為開發平臺，使用VB語言編寫程序，開發一種主要用于計算的化學軟件。

開發過程中主要采取了以下的技術路線：前期，對項目進行了詳細的需求分析和綜合的可行性分析，為軟件的編制提供現實可行的依據；中期，根據需要整體上規劃基本框架，對窗體和控件進行總體設計，詳細設計了整個軟件的功能實現；后期，進行系統的調試和生成可執行文件。

開發出來的本軟件能夠進行快速計算，用戶只需按照軟件的提示信息將相關的數據輸入完整，軟件就能自動處理數據并報告和顯示相應結果，操作方便簡單；還能夠顯示相關的知識要點和公式。而且具有友好的人機對話界面，性能良好，在WindowsXP及以上環境中均能穩定運行，比較實用，能解決復雜的計算問題，提高計算效率。

關鍵詞：Visual Basic；氧化還原滴定；化學軟件

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.
