单机版网络课件公式的动态实现

Dynamic Realization of Stand-alone Network Courseware's Formula

公式的处理是各学科尤其理工科教学课件制作中无法回避的难题。当前的主流做法是把公式转换为图片插入到课件中。公式转换为图片后就无法再修改编辑,导致课件的灵活性、适应性和可扩展性都很差。能够像编辑文本一样在课件中编辑修改公式并避免将公式转化为图片的缺点一直是人们追求的目标。故研究一种基于LaTeX和MathML,在单机版网络课件HTML源码中像编辑文本一样输入公式LaTeX源码而无需转换为图片的方法,并通过脚本设计实现课件文本和公式格式的事后一致化调整和控制,具有很强的现实紧迫性。

The formula is an unavoidable problem for all disciplines and especially science and engineering disciplines during the making of courseware. The current mainstream approach is to convert the formula into the picture and insert the picture into the courseware. The formula converted into an image cannot be modified and edited. Thus courseware＇s flexibility, adaptability and expansibility are very poor. A method which can input LaTex source code of equations into HTML source code in stand-alone network courseware based on LaTex and MathML like editing text without conversion from formula into images is introduced in this paper. And the post adjustment and control for consistent courseware text and formula format by script design are realized.
