物理化学实验教学仪器的一些改进

Physical Chemistry Experiment Teaching Instrument of Some Improvements

针对物理化学实验教学中学生的实际使用情况,介绍了物理化学实验中一些实验装置和仪器辅助设备的改进情况,并提出了一些实验改进措施。(1)动电势测定-界面电泳法实验,把塑料滴管加工使之边长使用,解决了该实验中的一些具体问题。(2)燃烧热实验压片方法改进。(3)过氧化氢催化分解实验方法步骤的改进。在实验教学中,这些仪器的改进取得了良好的教学效果,提高了实验效率。

For actual use of physical chemistry experiment teaching high school students, physical chemistry experiment introduced some improvements in experimental apparatus and instruments auxiliary equipment, combined, made some experiments improvements. （1） Determination of the potential move - Interface electrophoresis experiments, the plastic dropper side processing to make use of this experiment to solve some specific problems. （2） Heat of combustion experiments tableting process improvements. （3） Hydrogen peroxide decomposition catalytic steps to improve the experimental method. In the experiment teaching, improving these instruments made good teaching effectiveness and improve the efficiency of the experiment.
