摘要
对物理化学实验中"二元液系相图"实验项目,从改进实验装置、提升实验手段,改善实验教学方法等方面,进行了综合改革研究。研究结果在实验教学中的应用表明,从新旧装置所获得的实验结果,对比显著;基于Windows操作平台的数据处理软件能在一定温度范围内的任意温度下,消除阿贝折光仪的读数漂移,迅速、准确地获取二元液系汽-液相平衡组成,帮助教学双方通过观察图形及时对实验结果进行判断,及时发现问题、分析问题和解决问题。采用改善的教学方法,没有相应物理化学背景知识的一年级工科化学学生,也能取得好的实验结果。
The physicochemical experiment of Two - component Liquid State Phase Diagram is comprehensively studied from three aspects : improving experimental facility, bettering means of data processing and reforming experimental methods. The results of studies have been applied to experiment teaching. Results show that the improved experimental facility is much better than the old one in precisely obtaining experimental data. The data - processing software based on Windows system is programmed by the project team here independently. It is quite strong in getting constituting data from working curve due to its ability to calibrate a variety of deviations. It helps both teachers and students discover, analyze and solve problems. Freshmen who lack relevant physicochemical knowledge also gain satisfactory experimental results with reformed educational methods.
