多媒体教育软件中化学符号的录入和理解

Input and Comprehension for Chemical Symbol in Multimedia Education Software

研究化学智能解题的前提是研究各类符号的录入、识别、理解 ,这是多媒体教育软件中的一个技术难点。文章讨论了化学学科中特殊符号的录入 ,并设计出一些算法 ,这些算法能够从记录一个分子式的数据结构中识别出全部的反应物分子式、生成物分子式、反应条件等 ,从而能将用户录入的答案与标准答案比较和智能配平。

Precondition research of chemical intelligent exercise is input,distinguish and comprehension various symbol. It is one of technological difficulty about multimedia education software. This paper discusses input of special symbol in chemistry,designs some algorithms. These algorithms can distinguish from data structure of molecule formula,and recognize all reactant molecule formula,resultant molecule formula,reaction condition,then compare answers and standard answers,intelligently balance molecule formula.
